I'm looking for a good servo (micro?) to use on a HOB 1/12 P-51. I'm installing the Robart #123 micro retracts. Do I even need to use a micro servo?

I've seen references to the Hitec HS75BB retract servo, but I'm afraid it might not fit on the plane with 4 other micro servos.

Thanks.

You can try the Topmodel MR 2645 MICRO RETRACT SERVO

I think th hs55 by hitec is a better choice.
