One more thing. I have seen different threads you posted related to your modified Spitfire. Don’t want to rain on your parade but I think you have to resolve some issues before even considering buying new equipment. If you live close to me I will be happy to let you fly my planes for you to get a feel of this hobby. Many things have to come together to result a successful experience. Spitfire is not a plane for beginner or your first scratch build. I have seen my friends’ kids sunk $200+ on the “coolest” EDF or warbirds, put them together in a rush with wrong materials or components, launched and crashed in 5 seconds and then never touched RC plane again, I actually have two whole sets of Almost-Ready-to-Fly kits, including 8ch Tx, Rx, battery, charger laying in my basement that were abandoned by my neighbor’s kid. I have no meant to critic your works, just suggest you to combined your threads into one build thread, posting as many pictures as you can, showing the placements of electronics, control horns/linkage, your thrust angle and CG etc., so others can give you some tips. Please be open minded to constructive criticis.
Good luck!
