Razor: T/R Belt Tension?

[Vertflyer]

I need to tap the knowledge of this forum again.

I just got the boom on with belt around the main shaft. At first, I thought something was wrong because the belt had a REAL hard time even getting on to the gear. I even took the tensioner off and the belt seemed too tight. I double checked to see if the boom was on as far as it could go on both ends. I even wondered if they sent me the wrong belt.

When I turn the main shaft, it seems like the belt tension is causing way too much friction.

So, is this just the way the belt is? I know that the belt will loosen up in time, but can I get some assurance that the belt is just stiff to start out? In previous models, I've always had the option, at least, to make the belt way too loose or way too tight, so I could find the correct medium. With this model, I feel like there is no choice, even with the tensioner at the loosest setting, it seems tight.

That sounds a bit tight. I have mine set at the halfway point and it is just about right on tension. I may go tighter after a few more flights. Possibly a twisted belt?

Vertflyer, I thought the same thing when I put mine together, the belt just seemed to tight but after flying it a bit I realized it's just fine. In fact like muddbogger2 mentioned I had to tighten mine up another notch to keep the belt from slapping around in the boom with the temps in the low teens. Hope that helps!

If you have too much friction you should also check your auto unit , sometimes you have to break them in , it's very easy just put your mainshaft in a drill press and then take the auto unit and with the mainshaft spinning move the auto unit up and down a few times and it should be nice and smooth.
