last weekend while my motor was running i heard a sound like the clutch blow out.

the blades still spooled up when i raised the throttle.

today i tried to crank her up and it seems like the pinion is not engaging the clutch to crank the motor over hard enough.

is this possible that if the clutch linear goes bad you cant crank the heli over ?

i just noticed when i insert the wand into the helicopter the pinion just spends round and round freely

The pinion dose not engage the the clutch shoe, the starter shaft does it with the one way bearing in the clutch shoe.

Well, you said "the pinion was spinning around" The starter shaft has two large flat spots for the starter coupling set screws. I don't see how the coupling could spin, unless the shaft is broken right under the flat spots.

I doubt you'd hear anything in flight if the one way went, it would just spin the starter, I've seen that.

Bottom line, you're going to have to drop the motor and see whats going on.

Just before someone "corrects" me, I meant the one way in the clutch, if the auto one way went you'd definatly know in flight

Looks like the clutch screws came loose, did you use Loctite with clean parts?

There have been reports of the screws being too long, thus bottoming out in the hub and not fully tightening down on the clutch shoes. This allows the clutch to move slightly and slowly eat away at the screws.

Make sure to compare the depth of the hole versus the length of the screw when you get the new ones in.

By the look of that clutch, the "shoes" are bent too far out. Either it has been too hot, or the liner is gone. I'd change both while you have it down.

Edit: Fan hub is shot as well, clutch bore is hogged out so much the clutch will no longer register in the center of the hub. Too bad, nice looking fan.
