RE: Radio Gear for a .15 Gnat?
the spad gnat uses an aluminum u-channel fo the fuselage. So you need to use standard size servos. Such as Futaba s3003-hitec hs300 or jr 527 as they will fit into the u- channel and not fall around as with mini servos. the hitec electron receiver is a good choice along with a hitec super slim rec.
