Title: servo size vs model size
Post by: DennisZ on June 25, 2012, 11:41:55 AM

I would like to do it right way this time - prepared to spend some extra cash
on servos.
So, the question is what servos to choose to 3m Condor ?
I originally planned to use Hitec HS85BB/MG (MG for flaps),
but now worried if those will be powerful enough (3kg/cm).

Any thoughts/theories are welcome.

Hi Dennis,

The 85 will be fine, but MG everywhere!

I have played with a Condor last year. Nice machine!
