Help!
Servo for the hobbyking 1400mm sbach

I am buying the 1400mm sbach from hobbyking. I've read that the 9g aileron servos strip easy. Can some please tell me what size servo works? Will any micro servo fit? What's the best servo choice? I am leaning toward hitec, what have you upgraded to?

The answers you seek lie here.

Also if you scroll down you will see the dedicated forum for the hk 1400 sbach. Rcg has a great search tool also.

will the hs82 fit for ailerons? There dimensions is 30x30x12. I thought stock servos were something like 22x12x26 or something close

Wing servo cut outs

The stock wing foam servo cutouts may require just 2 or 3 mm. of foam removal ,across the wing,for HS82mg fit.
For your info. the mods that must be done to make this bird more durable, and airworthy.
Spinner,replace with Dubro .Stock spinner out of balance and hard to balance.
Fit a UBEC of switch mode type, dont trust stock one.
Tail wheel replace with Dubro or similair.
Cooling ,increase diameter of holes in foam at rear of cowl. a 70W. hot solder iron ok for this mod.
A larger air exit hole on belly of fuse.
Ensure good retention of canopy.
Consider fiberglass reinforcement of fuse landing gear area.
Check motor mount for security , may require a bead of epoxy glue.
Elavators , reinforcement, carbon fiber rod recessed into foam leading edge across both halves.
Fuse, reinforcement, carbon fiber rod or tube 3 or 4 mm. diam ,from fire wall to rear of canopy and just below canopy ,both sides.
