6975HB Digital Servos for Giant Scale P-47? (top flite)
One of our local hobby shops was having a 40% off sale on all in stock items. I went down and found 4 Hitec 6975HB Digital Servos and two 422 Pro serovs at a price which I couldn't pass up.
I picked up the 4 6975HB's for the Ailerons, Rudder, and Elevator and the 422's for the flaps.
It wasn't until I got home that I had a second thought about using these servos in this plane. Do you guys think these servos will be up to the job? I plan on packing this pig around with a G-62. AUW should be around 22lbs.

opps just re-read the post if the servos are over 4kg you should be fine, as for the flaps provided your using one per suface you should be ok provided you have mechanical advantage on your side ie- bottom hinged flaps top horned linkage, but I would prefer to see 6kg on each flap, 4kg for all others is fine.....don't forget the 2amp battery so supply the hungry little suckers as coreless tend to draw more power from constantly hunting for centre.

My biggest concern is that I read on a different site that these servos are not reccomended for anyplane over 12lbs.
Yet- they are rated:
Torque 4.8/6.0v :
I think it's the Karbonite gears that limit the weight application.
I'm thinking I'll need to sell these suckers and get something with metal gears.
