Good luck. Try to set the wing up with a little extra "angle of attack" (Ensure the front of the wing is slightly higher than the rear) so as to give yourself the best chance of procucing enough lift. Also use the stock prop. The extra load you will put on your battery through the speed control may just fry one or the other or maybe both. Part of the fun in this hobby is experimenting to see what works. You will learn more by experimenting than we can tell you here. Good luck and I look forward to reading your flight report for the FW-190J-3 Wolf Cub
