I bought a huge ARF j-3 piper cub from Hobby People and installed a Jag engines two cycle Ryobi weedwacker engine in it. It is about 28-32cc. It generates around 3 h.p.. My question is this enuff to fly scale? The plane is a 1/3 scale piper about 11 foot wingspan.Thanks Anchorboy 46

iv got a hanger 9 1/4 cub 100" wing span. its got a g23 and it is more than enough to fly scale..

Slingshot~ What does a G23 look like and how much pwer does it produce? Does the 23 stand for 23cc's? Also my wingspan is about 133",very big cub,Is your motor a glow or gas? What size prop should I use? Mike

mike, the g23 is 23cc 2 HP . i run a 16x8 prop, its gas . they have a g26 now , you might want to go with something a little bigger . mine has 100" wing span.

you can try it, but I think that a 45cc or bigger would be better., I have a mustang 50 in my 1/3 scale cub with smoke and fly's great.
Finnish wgt around 28 lbs.

I think I'm cuttin it a little short. Mike

MIKE., I THINK RON45 IS RIGHT, BETTER TO MUCH THAN NOT...
YOU DONT WANT TO MUCH ELV.

I allways try to have just a little more power than needed, you just never know when that extra power can save you untill you need it. Allso most 1/3 scale cubs that I have seen or read about
use at least a 45cc on up. you can see what your plane wgt is before you add your engine, If it's around say 24-25 lbs I would go with a 50cc or larger, you can allway throttle back once airborn. Hope this info helps.
