View Full Version : Tail Linkage Rod Z-bend stinks.

My Trex 450sa w/ futaba 401/s9650 had basically NO tail authority (righthand maybee 90 to 110 degrees in a second).... The z-bend on the linkage had a very sloppy fit to the stock 9650 round servo arm. The pinion gear is too big to fit any other servo arms I have, so I stared at it for a while. I don't feel like looking for an upgrade and waiting to get it so I installed a spare parts control ball to the servo arm and put a spare main grip linkage and ball link where I removed the Z-link from. OH MY GOSH! ::oThe thing piroed righthand 1080 degrees (three times) in what seemed like a little over a second! Stopped dead when I let off too! Fixed now! Oh yeah, i will need to whittle out a plastic servo clamp for a support since the rod will not go in line with the existing guide.
