Congratulations a successful maiden is always such a joy.
The stripped gears in an aileron servo in either of the two airplanes you had them in could be an indicator of surface aerodynamic flutter. Since you had the same servo in both airplanes. What happened to the twist was it in a crash or known flutter incident?

No known flutter in either plane. TheYak is a 20 cc Valley View RC gasser, very large control surfaces. I should have put metal gears in to start with. I did crash the twis,t but only pancaked the landing gear, no other damage. I think the servos just did not have enough umph for the yak. Actually should have had metal gear servos in the twist as well. Just thought I would get by with a cheaper non metal gear with high torque. At least that is what I'm thinking anyway. I have MGs in for the elevator and rudder. The servo must have failed on final approach. I was very surprised to seeing hanging down after landing. Limp like a spaghetti noodle.
