Ouch! $340!

Have you tried those gyros for tailerons/delta/elevons.

If I was going to put one gyro on a single axis with two servos controlling that surface, I'd do that gyro.

Since I'm trying to do a taileron set up here, I'm going with those JR gyros. I've been VERY happy with a $100 JR 410T gyro (no longer made) on my nose steering for years. They have been abused, fuel spilled on them, dirt landings, yada yada yada and they've kept on ticking!!!

I have been really happy with JR gyros.
