PMYC Business Cards – April 2017

PMYC Has Replaced its Supply of Business Cards

Jerry Walker purchased new business cards for the Club. Packets of cards will be available at the Pond from Bill Brown or myself. As you run out be sure to request more at the Pond or call Bill or Jerry.

The space on the right side of the card is for you to put a name/email address label. Jerry uses the Avery #—- (looking it up) clear stick on label. Or, of course, you can just write the information on the front or back of the cards. The label is a bit classier and likely easier to read but the handwritten certainly works.

If you want printed labels, contact Jerry Walker. He will do a bunch for you.

At the Pond – May 14, 2017

Today started out just like any other day. A light breeze and a half dozen PMYC members.

Zaily really gets into model yacht sailing with PMYC
Zaily really gets into model yacht sailing with PMYC

When I arrived at the pond at about 11:30 there was a Mom and her 12 year old daughter: Zaily (I have no idea how she spells it). I immediately offered to let her sail my Micro Magic – after I did some tuning. She was a bit timid but did say – Yes. Fifteen minutes later I was satisfied with the boat’s performance. It was time to return to Zaily, who was still there. Again my offer. Although with a little hesitation she again said
– Yes.

I explained the relationship between transmitter stick movements and the boat movements, then gave her the radio. Within 5 minutes Zaily was making the boat go where she wanted it to go; well, at least most of the time. I discovered that this was not the first time she had had an rc radio in her hands. She has experience with an rc car owned by a relative. A half hour later, she still had the radio and was in another world. Then, the boat broke down – the jib tie to the boom broke. My fault. I had just replaced that tie-down this morning. It looked like I did not CA the knot.

While I was repairing the boat Zaily decided that going to the swings was more interesting than watching an old guy repair the boat. Zaily did not return.

PMYC Meeting – Agenda – April 13, 2017

Note: The format of this post is a bit clumsy. Bill Brown’s notes did not convert as accurately as either of us would have preferred. But, they are readable – after a fashion. Jerry Walker (April 10, 2017)

Opening Statement

The meeting opened with Jerry Walker providing an overview of changes and updates made in the PMYC web-site. Emphasis was placed on accessing and using the site Blog. Regarding the current PMYC club membership, it was noted that seven  members have formally requested refunds of their 2016-17 dues. This issue needs both discussion and resolution. Sailing has continued weekly at the Reid Park small pond and has been regularly attended by six to eight PMYC Members. Due to the non-availability of Micro Magic kits, sailing participants have come to the pond with a variety of boats. One MM, however, has always been available for participants to experience the joy of sailing the new club boat.

Previous PMYC Meeting Minutes

None. Since the reorganization of PMYC, formal meetings and directional club resolutions have not formally taken place. It was determined by attendees that this meeting that this and future meetings will be formally recorded by an assigned PMYC Secretary


The agenda for this meeting was introduced by Jerry Walker.

Financial Report

  • Treasurers Report:
  • Checking Account: $549.31
  • Savings Account: $5.00
  • Total Balance: 553.31

Jerry Walker is going to obtain PMYC business cards using the same format as the prior ones. PMYC gave out almost 200 cards over a several year period.


ISSUE: Jim Haines, Acting Treasurer PMYC noted that a new and
separate model yacht club has been formed – Tucson Model Yacht Club, Commodore: Kip North. Formation of the new club was announced at pond side in January when PMYC sailing members arrived at Reid Park for the regular Monday PMYC sailing. Sailors were advised that competing that afternoon at that location would require joining Tucson Model Yacht Club (TMYC). Dues were collected.

PMYC currently has 23 active members and seven individuals have elected to resign and join TMYC. The seven resigned members have requested and were granted a full reimbursement of their PMYC dues.
DISCUSSION: Jim recommended that PMYC assets be frozen and not be
compromised in any way. Members electing to join TMYC did so
independently and unconditionally. Those PMYC members present agreed
RESOLVED: When joining, PMYC membership dues are not prorated,
but, not refunded at a future date.

A Thanks to Jim Haines

A very sincere note of appreciation was extended to Jim Hanes,
Acting Treasurer, for his numerous contributions to PMYC – contributions
that have helped organize the development of PMYC. Obvious club
contributions would include Jim and Jerry Walker’s efforts in developing our club web site, managing club financial needs, building club boats (Tribute), and regularly contributing to monthly meetings and weekly sailings. On the pond, however, in the heat of nautical combat, it is Jim’s quiet demeanor that soothed the rage that flowed through the veins of us mere mortal sailors. We never saw Jim walk on water to retrieve a distressed vessel, but, we knew he could. Thanks Jim !!

Micro Magic Status

Currently there is one MM sailing on the pond. Two club MM’s are under
construction by Jerry Robertson and Bill Brown. Four PMYC members are
awaiting kit availability in the U.S.

Building the Micro Magic: Jerry Robertson presented his partially
completed MM kit boat. He discussed several problematic components of
construction and several of the kit’s short comings. Mast straightness,
keel / rudder alignment, and union of the deck and hull issues were
discussed. Bill Brown noted he has conducted trial test of seven different
ABS friendly adhesives These and other construction considerations will be addressed on the PMYC web site. Jerry and Bill will be contributing to the site as they progress in their construction.

Community Awareness of PMYC

Ideas for promoting community awareness of PMYC were discussed. Suggestions included: increased visibility at the pond and use of the media and presentations at community club meetings.

  • It was noted that our early -on “Show and Tell” presentations at  the Voyager community was successful five years ago.
  • Bill Brown would like to see better quality club signage / club recognition at pond side.
  • Jim Hanes volunteered to put together a list of potential
    community and city wide clubs, their meeting dates, and contact
  • Bill will pursue the pond side signage issue and present at the
    next meeting.
  • Jerry Walker renewed the Club’s event on the Tucson Happenings website.
  • Jerry Walker has approached the Star and Tucson Happenings to do an article on the Club.
  • Jerry Walker has communicated with the Tucson Sailing Club and has a tentative agreement to present at their next meeting – April.
  • A once monthly sail on the weekend might help to attract younger folk to our activity.

Purchase of Micro Magic Kits

ACTION: It was suggested that the club purchase two (2) MM kits (when they become available in the U.S.) To avoid availability issues, The kits would be sold at cost to new club members.
ACTION: When available, PMYC will purchase two MM kits.

Club Sailing Schedule

At the next meeting a decision will be made regarding the move of our sailing day to Wednesdays and to finalize our discussion about a once monthly weekend sail.

Future Club Meetings

ACTION: Monthly PMYC Membership
meetings will be held at 12 noon the second Tuesday of every month.
Location and directions will e-mailed to the membership and be posted on
the PMYC web site. Meeting Adjourned: 2:15 PM Next Meeting at: Bill Brown’s home

PMYC Website Status

The PMYC website was converted to a blog in January. Think of a blog as being a diary. It’s primary benefit is that it now gives us a means of recording Club events and actions and information and making it available to all members without the need to send emails. The problem with the email is that future members do not see them. Virtually all member communication should be done via a blog posting. Send anything you want published to Jerry Walker, our website master. Also, you can Comment on any post. You will find the Comment link at the end of each post.

The ability to have the website automatically send an email to our distribution list containing all new posts each day is in development. In the mean time members are encouraged to visit the site at least weekly and look at the posts made since their last visit. An email will be sent to our distribution list drawing attention to our Club meeting agendas and reports.

Pricing varies widely but it appears that it can be found for under $100. Watch the delivery time information as it can vary widely, ie, up to two months (likely coming from Hong Kong).

Alternative Tx

There are many transmitter choices on the Internet. You want one that is 2.4 GHz, DSMX/DSM2 compatible. An obvious choice is a radio by Spektrum or Futaba. But there are selections on the Internet at very low prices. Ideally you also want your Tx to support Dual Rate/Exponential. This function is used with the rudder to improve direction control.

I found this radio (Tx and Rx) on the website during a casual browsing: (THE QUALITY OF THIS PRODUCT IS NOT KNOWN). Price about $44 with free shipping.

The view has been expressed to us that the MM kit sails are not of a good shape but that they work. PMYC has standardized on the kit sails as a contribution to keeping the price of the boat in the water to a minim
um. The Kit sails are flat panel, meaning they are made of one piece of material. Jim Bankson a past member of PMYC has offered to make us flat panel sails – presumably of a higher quality. The images below are close-up images of the three suits of sails he made for us for evaluation. At this time he is offering to make us these sails for $40 per suit – material of our choosing.

Building a MM – Email Exchange with Mike Eades & Greg Norris, Late March, 2017

This post, dated March 27, 2017, contains two email exchanges between Jerry Walker and Mike Eades of the West Valley RC Mariners (WVRCM) regarding the building of a MM.

The writer of each email is identified.

Jerry to Mike

We still have just one MM on the pond here in Tucson. Each perso
n who sails it for the first time loves it. It performs surprisingly well against the Victorias.

We have two boats under construction (one by Jerry Robertson – he has communicated with you). We are working up to an order for seven kits from GraupnerUSA in time for an anticipated mid-May avail

We are finding with the two kits we have that the mast diameter is a lot closer to 6mm than to 5mm. Thus, mast fittings aren’t fitting. In general, switching to a thicker mast is problematic, especially for newbies.

The venerable Micro Magic succeeds in moving its own kit box top to the shore.

The issue with the rear corner mis match between the deck and hull is disturbing, but not an insurmountable problem.

We are finding that with the one boat we have on the pond, built in 2009, that the mast is 5mm. We do not have stays on this boat. It appears to us that in a 5 – 10 mph breeze that the boat shows much more inclination to heal than to bend its mast. What is your thought?

In the list of Graupner parts I see the refererence to servo sizes. It’s interesting to note the significant difference in performance between the base recommendation (C 261) and the C 3341) Is there a general agreement in the USA of which servos to use? Or, at least their capacity.

Of our two kits, one has a main sail that looks decent. The other one has significant wrinkles near the tack. It would not seem possible with a flat sail for that condition to arise. Presumably, this is the basis for your recommendation in your article to replace the sails right away. We are going to investigate the feasibility of making our own sails. We have a member who became quite proficient at making good performing Victoria sails.

I look forward to hearing from you. We are very excited about our MM decision. And, our website is evolving to reflect that excitement.

Jerry Walker

Mike to Jerry

I am glad to hear your club’s enthusiasm for the Micro Magic is increasing!

I will comment on those of your questions that I can answer however I have not built a MM from recent kits, only the ARTR version. Greg Norris built from a V2 kit and wrote it up for an article in the MM feature in the next issue of Model Yachting. I have copied him on this so that he can add his thoughts.

I did not encounter mast diameter problems with the ARTR version. My original MM had a 5 mm OD mast and I used it successfully without shrouds so I don’t believe they are necessary on any MM.

I don’t know of anyone who uses Graupner servos in the US. I used to use the Hitec HS485HB as sail winch and HS65HB for the rudder. However I encountered some strange problems with the HS485HB in which the servo would suddenly jump about 20 degrees and stay there requiring re-centering of the servo arm. Neither Hitec or I could explain this and I eventually went to the Futaba S3010 sail winch. This required drilling new holes in the servo arm to fit the Futaba spline but after modification this servo has worked well for several years without problems.

There seem to have been some issues with sails in recent kits and ARTR versions, not as well made as the original MM kit sails. While they perform fairly well they don’t look good. I made some sets of single panel sails for my original MM which were quite successful but for my Champ Spec MM built by Mike Weston, UK I bought 5 sets of Graphite sails from John Tushingham. I have since replaced the A suit, due to wear, with an A suit from Catsails UK which are excellent and reasonable priced. Several of our club members have bought from Catsails who give great service.

Hope this is helpful?

I look forward to hearing how your fleet develops and hope to see some of you sailing with us here in Phoenix.


Jerry Followup to Mike

What is the meaning of “Champ spec MM”?


Mike to Jerry

Mike Weston in the UK used to sell and build MM kits and based on his and John Tushingham’s experience developed  what he called his “Champ Spec” configuration and built and sold many MM’s to this spec. I bought one to see what he did so that our club members could modify their kit builds to conform to his spec. There is nothing radical but he incorporated several minor refinements that improved the room in the cockpit, ease of locating the battery further aft for higher winds and brought the main sheet adjustment down into the rear cockpit in addition to using the preferred Mark I fin and rudder and Mark II bulb, set back so that the front edge of the fin was 25 mm from the forward end of the bulb. All in all it produced a well-balanced boat easy to adjust and sail. In the article I did on the first ARTR MM I bought from Germany I compared the features of the ARTR version side by side with my Champ Spec boat on which the ARTR design was based.


Jerry to Mike

Using kit parts should we be moving the fin location on the bulb?

We have concluded that we want to get the main sheet away from the hatch cover. One idea is to place a tube at the forward edge of the cockpit that extends just a little above the hatch cover. Thus, the sheet clears the cover and has all of its effect on the boom to be (almost) horizontal.

Perhaps you could find a few minutes to send me a pic of the component arrangement in the boat. Perhaps we can take advantage of your ideas.

On our Victorias we typically made a flat platform that one could attach the battery to anywhere on its length (Velcro) and have it engage the rudder post. Thus, the battery could be moved almost to the stern. We use four and five cell flat battery paks. Are you doing something similar?



Mike to Jerry

Awaiting Mikes response.


Greg Norris Jumped in

In Mike’s first response, he indicated that he had forwarded my email to Greg Norris, the Micro Magic Class Secretary. Here is his response.

I’m happy that you’re making progress!

I liked the new kit well, and I wrote an article about putting it together.  That article will be out in the early summer edition of Model Yachting.  In the meantime, please call me with any assembly questions.  In particular, if you are assembling any carbon edition kits, please give me a call for sure.

To your specific questions:


Graupner has been very slowly but steadily improving the kit.  The one I put together had a 6mm mast with a tapered top.  The mast was thick walled, and much heavier than I would ever use.  I suggest using either an older kit 5mm mast or a ~ 6mm SkyShark 2P.  The latter have been the usual choice for MMs for years.  They are nice.  The 5mm old kit masts are also fine.  The current European champion uses them.

Both are easily available: SkyShark 2P –  They are a reliable supplier.

5mm old kit masts – I have some of these on order.  Should be here in a week or two at the latest.  I’ll be out of town from tomorrow through 4/9.  They should be here when I return, and I can send you one.


I agree with Mike.  I would not race with the current kit sails.  I don’t have current websites for Graphite or Cat, and I wasn’t aware that Graphite is currently making MM sails. (Mike will know the answer to the last question and have the CAT website.)  The other common choice is VAM (  These are sails made in Spain by a guy named Victor Izquerido.  They are the most common European sails.  The prices are competitive with everybody else, even including shipping.  Victor is very reliable and quick.  I think that Cat and VAM are both very good ways to go.


I agree exactly with Mike, though we’ve had no problems with the HiTec 485HB.  But given Mike’s experience, it makes sense to go with the Futaba sail servo.  I buy all of my servos from ServoCity.  I’ve found them to be reliable.  (

Hope that this helps!
