Too Tall.. The FM radios wrok just fine. I woiuld suggest standard servos with ball bearing for a couple dollars more. Used motors can be a gamble in my opinion. If you can find one in your area and have the seller demo that's how I wouild do it. (before he (or she) dem's it.. feel the motor to see if its already warm
)
Ken... I'm learing about electric retracts as I go... Didnt realize they were so cheap. Even the twisty ones for the larger Corsairs. Thats' one reason I haven't serioiusly thought about building one but electrics have made it possible again down the road. Some sets say includes control module others don't seem to mention it. Figuring this out now. It also seems the same size retracts can run anywhere from 10 to 200 beans. Lado Tech seem to be the be all end all but they are pricey. To many kits, not enough time.
