Hello guys I am in the middle of building my first 50 competition extreme kit and I am having a problem with the torque tube gears. The gear mesh is so tight I can hardly move the main shaft with my fingers. I have removed the main shaft and gears and made sure everything was lined up and moved the main starter shaft blocks and everything is fine with the top gear mesh. But when it comes to the lower main gear meeting with the front torque tube gears its way too tight. Has anyone had this problem before? Could someone help me or give me some suggestions? I have contacted Chris at rc heliworkz and he had me take the torque tube apart and make sure all the bearings were in correctly and everything is just as is should be but still too tight. I have never had this issue before with a torque tube setup due to them not having room for adjustment. Does anyone have any ideas? Please let me know if you do I am open to anything at this point because I want to get this bird in the air asap.

Ive ran into this before. Now with everything removed Tail,TT ect. See if it spins freely. Now the only problem i have had was the Umbrella gears werent meshing correct. the fix to this is the gears can actually move. So when i was inserting the tail section and pushing the boom in they were moving causing this binding. the way to install is hold one finger on the front umbrella gear and one on the rear. Push the boom in that way. You sorta push the two gears towards eachother till the boom seats good then pull the boom back out about 2mm max to give a little play. If you are still having problems please contact me i will get this sorted out for you
