Hi, I'm sorry if this is not exactly a pylon racing question , but I figure you guys pretty much have the top end of "speed planes" and run them far more regularly than most other people..
I want to get myself a predator or viper airframe to use as a bench mark for various engine expirements(speed) in the 40 - 50 size.

I figure if I use one particular type of air frame as a test bed I'd be able to judge what a given motor has a better application for

..but what I would like to know is what servos would I use , I mostly use Hitech gear , if you could recommend a correct servo If its over torqued for the job I dont mind though but I dont have megabucks to spend, Just want the most compatible for the higher speed

thanks
