Would they happen to be the : TGY-390V HV Metal gear Coreless Digital Servo w/ Heat Sink 5.4kg / .11sec / 22.5g ?

These are the servos I'm using but they are a pain to make a decent servo mount that still uses the designed geometry. I plan to maiden mine in about a week.
Bob congrats on the maiden!
I have sitting on an Seagull Extra 260 an un-run MLD 28 gas. That might be a little more motor than this plane needs. Maybe the 2m version?
