RE: J-3 cub Identifly.
No motor goes to waste I like the way you think, were on the same page.
Just checked Eflight web page,
The brushless 25 I have will drag a 3 to 5.5 pound plane
On a 3 s or 4 S lipo. Still trying to figure that out. I have the 4S 1500 mah 14.8 V I think that will work but be under powered.
That is going in the Trike 3 pounder trainer I have.
I will PU the common sense motor for the cub. 24 to 44 ounce model puller They have.But was also thinking it might be better for the cub that it only weighs 29.60 ounces.
Just gonna have to figure out the prop sizes.
I know this is probabley 2and nature to you and Thank You for all the help.
Sorry for beating a dead horse.
Just wish my LHS was more knowledgeable about planes.
