Is there a servo (preferrably JR) that fits entirely inside the fin cavity of the Skymaster F18, without having to make a 'bulged' cover plate. The cavity in the F18 fin(s) are very thin, and therefore available servos to fit would be hard to find.

Presently flying Skymaster F15 with full tank/missile load, and building Libertrau Dual seat F5f (3.46 metres long)

Any help on the servo type would be appreciated
