I think Duke had other problems about that time.

    The 29 was definitely advertised, and I knew several people who had them in the era. It was a decent performer at the time, slightly more powerful than a OS-25S and less than a OS-35S, nothing to write home about but satisfactory. They had the same issues of the other Fox engines at the time, sometimes requiring a cleanout and frequently required lapping the piston followed be very extensive break-in to get it safe to fly with.

Looks great with no more flights than you have on it.   You are living right when the engine quit when it did.  Mine is usually vertical when the engine decodes to quit.   If I didn't have so many kits now and planes ready to fly, I would consider it.   By the way I do like the out lines of the design.

Wow! The planes look great Mark!

   When I was working on this design
I never considered it as a Briefcase airplane.
Now that I've seen your "Kit" I'm going to
keep one in my car. Ya never know!

   I am a bit concerned about your plane
rolling in. Mine (Baby Bees) got a little light
on the lines at the top of the loops but it
had decent line tension.  Any chance you
forgot the nickle tip weight?

   The standard practice with Mann-Winn
trainers was to shove a length of CF rod
between the flutes to stiffen the wing.
I wanted the dihedral a'la Cox, and the wing
works well without it. No inverted stunts though
it does seem to fly reasonably upside down.

   I am excited about your electric version.
Please please please post a flight report!

  Today it's bright and sunny and about minus 15f with
two feet of snow on the ground. I hope it melts soon.
I have airplanes that need flying.
 

Cheers!

  I have no specific knowledge at all, but I anticipate that you will have a problem finding a prop that provides the right combination of RPM and in-flight speed. I expect the issue will be that you need 7" to get decent rpm, but 4" of pitch will be way too much. If you can find a sufficiently robust 7-3, that's where I would start.

   You can also use reduced diameter to decrease the efficiency. I think you will find 8", and possibly 7", too efficient. I am sure you could start it on a 10-6, but the big mistake people tend to make on modern engines of all types is trying to run too much diameter. That went out in the 4-2 break/ST46 era. You need to rev up to to make the engine happy, and that will more than make up for lost efficiency. IT must be extremely inefficient in level flight or even a .10 will pull the airplane far too quickly if it hooks up all the power it is capable of. The alternative is to detune it to remove some of the power, which is what the Head Gasket Patrol and guys with Dremel tools attempt.

    This is true even at the highest levels. Dave and I are running *much* smaller props than the engines will safely manage. I made the flyoff for the first time and finished 3rd in 2000 running what was previously David's "break-in prop", after having buzzed it down a few times. It wound up at 11.25" - on a PA61 capable of the spinning same prop at 13.5-14".  Same with year I won, I buzzed the prop on Top 5 day, didn't even clean the end up, and it was down to about 11.75 - from 12.5.

We always used 8x4 APC on the FP 10 on the Akromaster, with good results on .012 x 50 ft lines.

contest info

The 2015 Nats and Team Trials will be held in Muncie, Indiana over 8 consecutive days in July.  See the attached flier and entry forms for details. 

A few things to keep in mind:
Hotels can be hard to come by if you wait too long.  There is a big triathlon in Muncie over some of the same days in July.
Nats includes 4 official AMA events (f2d, f2dfast, 1/2A, fast) and one unofficial event (speed limit)
Nats F2d will be triple elimination, all other events will run double elim in first round (similar to past years).
TT F2D will use the MACA selection process for team selection, full triple elimination, top three finishers + top junior makes the team
Volunteers are always needed! Let us know if you can help out.

One of the items that increases costs to the consumer is the cost of supplying hard copies, both the copies themselves, and the cost of shipping them, especially to other than US locations.

CadClassics sales policy;

I must rely on the honesty of my fellow modelers for this next to work.

I will supply the drawings as Adobe PDF files. You will be licensed to print two (2) copies, for your own use, for a charge of (US) $5.00 per sheet. These files can be taken to A printing house, such as Kinko's, that can supply large document printing, where they will print them for a reasonable cost to you.

I can ship such files electronically, as attachments to an e-mail. You'll receive them quickly, whether local or where ever you live.

The easiest, and best way to order is by sending me an e-mail letting me know what you are interested in, then, using PayPal, to my email address, jobelcrank@yahoo.com. Once the funds arrive, I'll e-mail you with the file as an attachment.

Pretty simple.

For those not desiring, or willing, to use PayPal. It becomes slightly more difficult, but, not impossible. Send me an e-mail, at jobelcrank@yahoo.com, detailing what files you desire. I'll return an e-mail giving my snail mail. Send me a letter, with your order, and a money order, we'll be in business.

I'm listing plans categorizing them as to sport, stunt, or Vintage Combat Categories may be broken down further as Profile, full bodied, twins, Classic, 70's.

Hi Frank -

I have a needle you may be able to use.
PM me.

Thanks for your kind words. I hope to lay out the methods of payment. I believe I've made it much simpler than it was on my web site.
