Your radio and RX don't know who made the servos!! Look at the JR 8411s, I bought out servo City some years ago when they had A close out on Hitec 6985s. Just get the best you can afford but look around for sales. I got those HTs for next to nothing when the new models were commng out. A shame, I just traded away 4 of the 8411s last week. 77 is correct, you want as much servo power as you can get with that little plane.
I have A nice brison 2.4 that will fly that plane very well!!!
