What do I buy to put these props on this motor?

I know this is a dumb question (you guys have been ridiculously patient answering my dumb questions)... But I ordered some Graupner props to put on my XAircraft Hexa w/ the XA motors.

What prop adapter do I buy so make this work?

These props: http://www.mikrokopter.us/shop/index...product_id=245

These motors: http://www.cnchelicopter.com/servlet...s-P1001/Detail

Or will they just fit? The XA has an odd-shaped fit, which is why I'm asking. =)

The shaft on the motor looks really hard to find a proper adapter. The shaft is 4 mm but the hub on the Graupner prop is 8 mm. So you need to get a prop adapter that will fit on a 4 mm shaft with a 8 mm shaft for the propeller. You probably have to cut the shaft on the motor so the prop adapter won't be so high. If you have a machine shop near by I will just get the shaft changed.

Put together a machine shop and make your own adapter! How many suggestions do you want?

Make a 4mm ID and 8mm OD sleeve and put the prop on the existing shaft.

Get creative!

Yes but the issue will be the threaded area on the shaft. If you use the prop adapter with set screw the set screw will bite into the threaded area and damage the thread. If you use the prop adapter that uses a collet the collet may not have enough surface area to hold. Then again the threaded area may deform the inside wall of the collet making a good contact.

I cannot tell since I have never put a prop adapter on a threaded shaft. I have enough machine at my workshop I just change the shaft to some drill rod blank.

The motor shafts are threaded. All you should need is a 4mm to 8mm spacer. The slow-fly props usually come with adapters. After you bolt on the prop you will want to dremel off the excess shaft. Wrap the motor in a plastic bag so the filings don't end up in the windings and magnets. Leave a couple mm above the prop too.

You may not get the performance you hope to out of the E-props. They are usually a little heavier than a good slow-fly prop. The extra weight translates into sluggish changes in motor speed. Since we are relying on the change in motor speed to control the attitude it will mean sluggish response. Most people have gone back to APC slow-fly props. They seem to be the best in endurance and the best trade-off for weight versus stiffness.

Blueskyrc sent 4mm adapters along with the props last time I ordered some. Might want to check with Dave and see if he can send you some.
