thanks for the replies, i managed to get the throttle rod replaced with a tube/rod system and then built in supports for the tube, so it no longer bows. it required me to change posisitions of the rudder and throttle servo, this made a much better line up for the throttle and an ok one for the rudder too.

my biggest problem is the elevator linkage system, it is TERRIBLE! Those little white tubes that go in the outside tubes (already mounted in the plane at the factory) they bind like crazy, my hands are burned from sanding those tubes down for hours, then they would still bind, so i lubed the tubes with tons of vaseline, they still bind, so i repeated the process, hours later the rods were sanded down to thin little sticks and they still bind, it seems the action of pulling them apart the further the tube goes in the worse it gets. but replacing it with a metal rod isnt an option cause its two tubes and two elevator halves that are joined. please any assistance you guys can give, anything you might remember.... thanks

edit: i bought 2 rods to try, i havent tried it yet, i am going to combin the two rods together and then a third coming out the otherside to replicate the factory linkage. i dont know how i am going to connect all 3 wires together, they have to be spaced, so i cant just solder them all together at the ends, the 2 rods that go to the elevator need to be like an inch apart or maybe even 2 inches apart.
