Title: Need some suggestions
Post by: Mike Griffin on February 27, 2014, 09:35:52 PM: I was going through and making and inventory of my engines last night and found a new OS .20 that I would like to put on something. Any suggestions on a plane that would fly good on a .20 size engine?

Thanks

Mike

A Sig Skyray would also be a great candidate if you keep it nice and light. Other than those you could pick about any good 'ol .19-.25 design...

20FP or the '70's 20-s (baffle piston)?

Jr Flite Streak for the older 20.

Post by: John Park on February 28, 2014, 08:46:37 AM: I had an early steel .25FP-S, completely box-stock, that used to pull a 36 oz. flapped profile own-design (span 49", area approx. 480 sq. in.) very nicely, turning a grey Graupner 9x5 on 5% nitro. From what I hear, the .20 is just about as powerful, so any smallish .35 design, built light, should fly well. If you'd like a full-fuselage classic, how about the English 'Scimitar' design by Bill Morley? Nice-looking model, originally intended for an unsilenced Veco .19, I think.

I fear it (the model, not the powerplant) may be a tad undersized, but I was going to suggest the new Brodak Cub (http://brodak.com/cub-kit.html)

Mike,
Look up Bretts setup for the 20FP on the forum and do it just like that...it's a giant killer!

Enough said!

PS: I flew a Flite Streak with one of these things and it was pure magic!

I guess I have been asleep about Brett's formula. I will sure look it up though . Thanks to everyone for their help.

Jr Nobler?!!! WAY too small for a 20FP. It flies fine with a Medallion or Sportsman 15. A regular Nobler is closer to right.

Jim flew the "RSM box-cover art" Feno on the 20FP and power certainly was not lacking. Larry Fernandez had a Still Stuka with a 20FP, and it flew well.
