thanks for the info my geras are actually loose on the shaft I think I need to get ahold of Horizion and see it they will or could send me a new shaft I put a brand new gear on the shaft holding it by hand a a very slight turn or try wobbleing it by and and it flops around. so I was wondering if maybe they had a bad batch of shaft or torque tube ot what ever it is they call them I'm gonna call them this morning and talk with them and I'm also gonna order some new gear sets and a couple shafts to try and see if any of them are tighter I've been doing this hobby 22 or 23 years plus and this is just sloppy craftsmanship
