RE: Electronics
You can use any brand of servos with any receiver. You just have to make sure the wiring is correct. Also, if you are going to use older Airtronics servos you'll need to snip off the little plastic tabs on the plug. But after that you'll be fine. I've got some 20 year old servos that I still use this day. I use them on my less critical planes and I only use them for the throttle servo, but they do a great job so why replace them if they work???
Take a look at this chart and see if it helps you out.
