Don't force it off the ground. The T-tail will try and lift the plane before it is ready to fly. The wing will then block the hrozontal stab and the plane will sit back down on the ground. You will bounce along a few times before it is ready to fly. LAndings require you to keep a little power and don't flare until you are ready to land. Agin, the wing will block the stab and the plane will sudenly just lose lift and smack down. Not a hard plane to fly, just alittle different. The .60 will be more than enough power when she gets in the air.
