which profiles would you guys recommend? sorry for all the questians just want to make the best choice, plan on ordering some nice servos and a light lipo battery and charger. but my avistar weighs at least 5 pounds and it has got loads of vertical with a 10x8 and the .51 spins that prop about 11000 -12000 rpms last time i checked. so it should spin a 12x4 prop a bit faster. thanks for all your help.
