Telemaster 40 Servos?
Can anyone advise on whether micro servos like the HS-81 (instead of the recommended HS-322) would be sufficient for the ailerons and flaps on the Telemaster 40? It'sfaster but a little less torque but I'm not sure if that will matter for this trainer:
SPECS (HS-81):
Transit Speed: 0.11 sec/60° @ 4.8V
I can't seem to find any specson the exactthe forces required for each control surface. I wish they would include this data in the kits and not assume us modelers just need a "recommended" servo. We like to analyze this stuff!
Thanks,
Art

RE: Telemaster 40 Servos?
I would not use a micro servo on a 40 size plane, except maybe for the throttle. Even then, only if weight were a consideration. Standard servos are cheaper. I have been using Hitec 311's for all of my 40 size sport planes for a long time. They are $9 each.

RE: Telemaster 40 Servos?
Yeah - probably a good idea. I just thought that the smaller servos would look better since they hang below the wing on this model.
