Title: 4mm Collet Style Prop adapter for BadAss 2320 820Kv
Post by: Dennis Toth on June 25, 2024, 04:35:40 PM

I have been fighting a vibration problem with my BadAss 2320  820Kv motor setup. Turns out it is the Collet Style Prop adapter. Seems that although the adapter I have says it's for 4mm but it is not running true causing lots of prop noise and vibration like a Fox35. The adapter unit is from Great Plains. Is there any better units out there that you guys have used on 4mm shafts?

I am using the prop adapter on my 2320's but I have had similar problems with the 5mm.  These are about the cheapest collets out there but they really work.  You get a 1/4 28 shaft that tightens easily.

Thanks Ken, I ordered 2 so will have a backup. I did a no-load motor only test and no vibration or shaft wobble so if the collet is just a little off it will shake around even though it is tight on the back part of the shaft.
