I'm Getting ready to start assembly on a G-Trick 90. Looks to me like they intend for me to drive the elevators with a single servo pushing a "tuning-fork" setup. Perhaps a better installation would be to use one of Central Hobbies' ball bearing dual coupler devices that drives with a single pushrod and extends a couple of pusher arms outside the fuse. Any advice?? Also, is it worth the $$ to use carbon fiber/titanium pushrods and high-end control horns??
