Screw-on Prop adapter for SK3 4250 410kv

Galand

The 3 hole screw-on prop adapter that comes with this motor is only 6 mm diameter shaft and only 24 mm shaft length. This is ridiculous for such a heavy motor. The diameter should be 8 mm and the length at least 35 mm like the FMS adapters. I looked at the NTM adapters but the drilled-out base is too shallow. Are there any other 3 hole adapters out there?

I found an adapter: http://smallpartscnc.com/index.php?route=product/product&filter_name=FMS SK3 42 Adapter&filter_description=true&filter_sub_category=true&page=2&product_id=129
But it is $15.95. Almost half of the price of the motor!
