These are very unbalanced, its horrible. i do not balance my prop, put it on these adapters, and slowly turn the prop while holding the motor still, till the balance point is found. then either add or cut some weight off the prop till its almost perfectly balanced.
I buy one of this in 25.09.2013, but my order is stoped after the payment is confirmed and there are of this product in stock. I am trying talk of a customer and in the support centre, but anybody answer! I will cancel this order. I try speak with somebody, but anybody help me.
I can't seem to find a "reversed spinner thread" version of this, can anyone tell me whether this would still be necessary now that the prop adapters are actually mounted to the outrunner casing? Maybe just thread lock will do? Just worried about one of my props flying off!
I have been using it as a pusher. I used a very small amount of blue threadlock and I tightened it a little more than would normally. Never had it a problem with the prop coming loose and I beat it pretty good. :-) I was still able remove and replace the prop. The threads are a bit loose on this adapter so the threadlock does not have a very strong grip. Easy to remove, but protects you from vibrations.
I don't use the spinners anymore, they are not balanced and cause a lot of vibration. A few times they become loose in flight. I now use 5mm nylocks instead, which seems to have solved most of the problems.
Arrived nice. should have been included in with the motor. Anyway, can't complain now.

Overall very nicely machined. However, the cross is a bit weak, compared to other sources - it bends at the inner holes quite easily. This is almost not noticeable when actually attached to the motor, but still it's a bit weaker than others.
The propeller mount fit is sometimes very snug, so you have to use the screws to actually drive it onto the motor (by hand it wont go on)
