Dubro Products DUB541 2 in. 3 Blade Spinner, White

This spinner is very good quality: the adapter rings fit very snugly in terms of both the interior diameter and exterior diameter, and I especially liked the hardware to hold it all together and the fact that 5 different rings are available for different shaft sizes. Like most spinners, this one should be balanced; even so, you could probably just use it out of the box if your not high performance minded. It did not fit my Xoar 11X6 PJE-I three blade woody. After carving up the interior quite some to make room for it, it did finally make it in, but then of course the balance was way off and I decided not to use it after all. In this case, balancing it would be imperative. I installed this prop with a Hyperion 4mm wide collet with a 6mm shaft, and needed every bit of the 35mm collet length to make it fit. (This adapter has an especially thick collet retainer ring.) I suspect that if you use US made props with 1/4" bores, and adapters with collet's of about 28mm in length, it should come together quite well.
