RE: Guys we need to know everything.
My equipment preffereance is identical,
85MG X 4 I even use them on throttle as a front end collision was stripping a plastic geared mini throttle servo even the 85 plastic...Stay away from 81's totally differant than the 85.
I am so impressed with these Hitec 85MG that I use them on many of my sport models (one model does 125+MPH with these installed smooth as silk) The major portion of my standard servo fleet consists of JR4131 servos.
Dual aileron servo's almost doubles your torque over 1 standard servo, with 60" inches of aileron thats a good thing. really improves performance.
Receiver preferance is no big deal other than you want one in the .75 oz or less range. Some I've used Hitec555, Hitec SuperSlim 7, Berg, Expert, and FMA. Super slim 7 Hitec has taken the most abuse by far and still works, the rest all seem to give glitches after abuse, but none have failed in the air.
Radical rc for battery, 4.8V 300MAH NMH, last as long as generic 500MAH Nicads, $9 is without plug ends, $12 with.
99% combat pilots ,DO NOT use a switch, just a plug in connection.
These recommendations are not required, but just a guide for those that actually are going to gear up, the price of these items would be equal to any other choices. Servos are a bit more only cause there metal gears, combat strips allot of plastic gears so it will pay for themselves in the end.
