For a TD 09, I had good success with a Jr. Flite Streak, and a 15 size Shark, also a #4 Easy for Old Time. A medallion will also do pretty well. I ran a Cox 7x3.5 prop. Sig Champion 10%nitro, 20% oil, half and half, and backplate pressure with oneway valve to the uniflow. Release at 14,500 to 15,000. Need about 2 oz fuel for a modern pattern. I used 55 to 57 ft eyelet to eyelet .012 lines. A medallion will probably need a little shorter lines.

I have a Medallion in a Mini Peacemaker.

Plan available on Hip Pocket http://www.hippocketaeronautics.com/hpa_plans/index.php

Nice for a relaxed flying session, on 42' lines.

I have older Fox .15's but never tried running them on bladder. Try it on the bench and see if the needle threads are too coarse.

Do not use the Li'l Satan. It is WAY too small and is designed for a tank mounted 1/2A engine.

For a .15 you need the Junior Satan. I had a MAX-III .15 on mine but the Fox .15 should work fine. I would suggest .012x52' lines.

Good luck with it.

Jay,

No reason the Fox 15 won't work on bladder

EXCEPT!!!!!


They have a totally cr@ppy NVA, change it for one that works, like an Enya or OS and you'll be in business.
