gregkabob,
DUDE ! ! How did you not mess your pants when you saw that ? YIKES ! That's like a bad dream ! GLAD to hear its all O.K. on the inside. Its amazing how far these things travel and still make it in good shape.
Shadow,
Somehow your shredding belt and low flight times are related. Your belt is rubbing doing two things: 1. Eating the belt 2. Pulling down your battery
Take a CLOSE look and see where it is rubbing. Where are all the shavings? Look closely in the area the shavings are.
Let us know what you find out and DON'T overtighten the belt. Also be careful not to strip out the roller guide screws when tightening them.
GOOD LUCK !
Mine was rubbing on the boom where the belt enters the boom because things were off. I got 'er fixed and everything is fine. What I did was re-drilled the main shaft and raised the pulley 1/32 of an inch. NOW the belt is in a straight line from the pulley to the guide rollers and into the tube. Before, the belt was at a downward angle going from the pulley to the tail boom. NOW it's straight across. I did that because I didn't like the downward angle of the belt and from an engineering standpoint...a straight line will cause less problems and less stress on the guide rollers. It's a modification to improve performance of the belt system and in my opinion...needed, and worked fine. You guys may want to look at the belt path from the pulley into the tube, you'll see what I'm talking about.
