Prop Spacer for 6mm Extended Shaft
thingiverse
Prop spacer for 28mm (stator measurement) Cobra motors that can be outfitted with the optional extended shaft by Innov8tive Designs PN:C-BPAL-28 (4-Hole). This pushes your prop back 19mm. UPDATE 3/30/18: I added a 5mm spacer for those looking for a bit less extension. This spacer has been tested on my HC44 at high speeds and works wonderfully. UPDATE 3/27/18: After some testing I've concluded that in order to use this you must ensure that your thrust angle is 100% perfect. Any deviation, even the slightest, will be exaggerated by extending the prop rearward. Tuning is required in order to get the desired performance. That being said, I do not recommend usage of the spacer in high speed applications. UPDATE 3/26/18: Install as shown in the pic. Other configurations with unbalance the prop. There is a lock washer in between the prop and nut. Motor > Extended Adapter > Prop Spacer > Supplied Thick Black Washer > Prop > Lock Washer > Lock Nut
