Hello to all,
Thank you for all the useful info that has been posted on this thread. I too have also built this Super cub and love it. I have been flying it for about 3 months now and always have a great time . I went with a electric setup on this project because I have gotten rid of all my glow stuff and only fly electric now. My set up is as follows,

1. Scorpian 4020-14 motor ( 1.5 to 1 power ratio)
2. Castle 80 amp ESC
3 Hitec Hs 475HB in the wings and 485HB in the rudder and elevator
4. 16X8 Xoar prop
5. I use a 5S 5300 MA 35C pack

It comes in at 8.5 lbs all up weight. With this pack I get 35 minuts of fun. I useally split it up into 2 or 3 flights.
I access my pack by taking off the wing. With the disarming plug on the outside of the plane, I dont have to worry a bout the pack wearing down between flights

This is a very solid plane and very stable as you would expect a cub would be. I use my flaps all the time for 6' take off's and slow landings
I have had alot of fun doing flat spins with this plane and when i say flat I mean frisbee flat, but be careful it takes at least 3 rotations of the plane to recover. So give yourself pleanty of highth, oh yeh it helps to have the CG a little towards the tail. I can do 200' inside loops and can also do very nise axial rolls. But the best part is flying low and slow. I intend to put a tow hitch on the plane and tow my buddies gliders up.
Well thanks again for all the info and please check out my picks, The 2 flying pics down below where taken on the same flight the moon was in the east and the sun set was in the west
Thanks Fizzy
