For me it is. Right now I have a Hitec Flash 5 system X radio. It costs here (full set) about 250$. I have only one model engine and it is an old magnum .15!! I have about 5 models for the same small engine. The same is with servos. I have 7 servos(4 standrad, 2 mini and 1 micro) So now you can see that anything over $50 for me is expensive!!!
