RE: EDGE 540T ARF
Maybe. You'll probably be ok. Be sure to build plenty of speed before lift off, and keep the speed up on landing, and get familiar with how it stalls early on and at a good altitude. And set the CG towards the front of the range for now.
I've not flown that particular plane, but if it's par for the nitro models course, be sure to double check everything. You might even want to measure out the wing and run it through a CG calculator, more than one kit from them has had the CG listed wrong in the instructions.
