I'd forgotten about the Bixler my kit is Specky as well , every time there's a sale of servos in china I usually buy a dozen , at £1.50 each they can't be matched , and for the things I fly , probably not worth risking an expensive digital servo, and for the foamies a cheap orange or lemon receiver ... getting expensive these days , last one cost me £11Something like the Hobbyking Bixler is good. Cheap, lecci powered, good wingspan, pusher prop so less likely to break, and foam, so can glue together after a crash. You will need radio gear. All my stuff is Spektrum but you are spoilt for choice really.

I taught a few people to fly with one of these, an ST Models Discovery.
