Many beginner sailplanes are 2 meter in size and can take standard size servos and receivers, which is what most of the radios include in their packages. Planes like the Spirit, Gentle Lady, Sig Riser, the Gentle Foamy and the Defiant can all take standard size servos. These are pure sailplanes. I gave you a list of electic electric gliders earlier.

Parkflyers on the other hand are small electric planes. These need micro servos and micro receivers. Wing spand in the 30-60" range and typically 8 ounces to about 30 ounces in weight. I gave you a list of electic parkflyers earlier. If you put two standard servos at 1.6 oz each and a standard receiver of about the same weight into a 12 ounce fuselage, it would fly like a dog if it could even fly.

The Flash 5SX listed above is one of the few radios I have seen that can be had with micro receiver and servos. Packge is about $180.
