No thanks JPF. the ally is like a crumple zone if you have a mishap.

If you want a weak link to reduce chance of bent shafts then use a wood prop.

Each to his own but i prefer my collets to stay on the shaft. In fact I'd rather have to replace a shaft now and again than keep loosing props, not that I've found shaft bending to be an issue when using the Hacker collet.

I fly vox props on all my planes. ,,, and my PA collets DO stay on the shafts.
Indeed, each to his own.

Lets not confuse the issue any further and make it clear that the motor in your AMR is not a Thrust 40

To be fair on the AMR personally I also never had any problem with generic ally type collet adapters, though from the posts here plenty have had issues. It's on higher power planes that I've found the ally ones just arent up to the job at all. Out of preference I'd go for the Hacker ones anyway as they are just better quality bits of kit IMHO.

I hate collets. I hate front mounted motors. I have never had any kind of problem with X mount. I have lost collets on my T 40. I have bent a zillion shafts. PITA!!!!!

I prefer bolt ons too, in addition to being more secure, they wick heat away better too.

That said, I've never lost a collet since learning how to install them properly. Remember. It's the balance of wet and dry friction that secures the connection.

- The motor shaft must be clean (ensure you remove the oil that's present on all new motor shafts)
- The collet 5mm ID must be clean too. There is always oil in these too from the machining operation or packaging.
- The tapered cone must be lightly lubed or it can't push the collet ID onto the motor shaft with enough pressure
- The nut and threads must be lightly lubed also or the prop and outer cone will slip before there is enough tension.

I've seen some collets that have developed ridges on the tapers from over tightening. They never work once they start to look like that and need to be re lapped / replaced.

Thats just a PIA

with many others, you can simply slide on and bolt down, and forget about it.

new collet works perfect today and I have to say I love the xoar 14x7 on this plane way more than the vox 13x7 that flew off, this is a fun plane, really really easy to fly and look good doing so.

14x7 VOX or Xoar is the only way to go. Speed and thrust is perfect.

I flew 13x6.5 VOX before the shaft went flying and was ample power aswell
