Building airplanes isn’t for everyone. Flying RC can be very technical and sometimes it’s nice to eliminate guess work by having an airplane that is just ready to go. The disadvantage to these ready to fly aircraft is that they can be difficult to repair after a major crash.
We love DIY aircraft because it is an inexpensive way to get started and you can always reuse the electronics from the aircraft on another kit or project. As most people know, at Flite Test we make airplane build kits that make it incredibly easy to build and fly your own RC aircraft. We also supply build videos and PDF plans.
Starting with a computer simulator is probably less exciting but it is absolutely the most efficient use of your dollars and time. Flying on a simulator is the fastest way to build up the critical muscle memory needed to fly actual aircraft. With simulators there is no repair time, just a reset button.
