Title: Stumpy
Post by: minnesotamodeler on September 14, 2011, 04:01:17 PM
this is a 2nd iteration of what I intend to be a fun, tough sport plane, maybe even a stunt trainer mostly 'cause it'll bounce, not break, when altitude runs a little short. Top MM beam extends through the wing all the way to the tail.  Stab/elev. from 1/8" thick balsa.  Ply. nose doublers extend back extra long.  Single wheel can't bend up into the wing.  Swept LE means fewer square-on hits on the wing.  Droopy diamond airfoil means easy, warp-free construction.  Ummmm, guess that's all the features I can think of right now.  Span = 20", area 125 squares.  Power intended to be Norvel .049.

Ray, great idea!  Is this to be kitted?  Not a lot of norvel .049's laying around, would a cox medallion or an ok cub work?  What tank would go good here?  I do like the thinking for a tough little trainer that can stunt well.

Hey Ray,

I may ultimately kit it, if I can get it to fly the way I want.  Yeah, it's small enough most any .049 would fly it OK.

the tank, on mine anyhow, will be balloon in a canister mounted on end behind the engine, here's a pic of an earlier one.

A standard tank would have to be mounted on the inboard side to have enough room.
