Hobbyking ASW28 EPP (2M) Foam wing servo replacement

Well my Hobbyking ASW28 has probably had about 40-50 flights and as the servos are 'no name', I have decided to replace the wing servos with 9g blue Hobbyking servos. I haven't had any problems with the existing servos but the 9g blue ones are pretty cheap and should be better than the existing ones so I decided to give it a go. They are glued in place so have to be cut out. The servos are inside the fuselage when the model is assembled so as long as they are security mounted the look doesn't matter too much (as long as they are mounted properly). I saw a Youtube video where someone moved the servo out on the wing but I won't get carried away like that. Anyway, its nice having no horn showing with the current installation.

Having cut out the servo...

New servo ready for mounting.


Well after the first flights I was a bit disappointed in the roll rate. I thought the HTX900 servos appeared more responsive than the no name servos and therefore expected slightly better control but no. I've decided to mix in some rudder to improve control a bit.
