If steel pinions are produced........

[Jomaba4308]

If someone were to produce steel pinions for the Protos 500, especially the smaller 12t-14t sizes for improved wearability, would you upgrade or stick with the stock lightweight aluminum?

Third choice... I will still stick to my solid steel pinion without OWB.

I'm done with OWB for the Protos. Initially, I had plans to mod my home-made 13T solid steel pinion to run 6mm OWB but after having flown the solid steel pinion well over 1000 flights with no complaint, I don't even bother executing my plan.

Over 5000 flights on two Protos over the last 5 years. I've had pinions wearing out and replaced but I've never had a problem with 15T OWB. I've used some 14T pinions too. Also no problems with OWB. Maybe I'm just lucky. Or the pinion teeth wear out before the OWB does. I don't grease my OWB. I don't even put anything on them.

I started this because of the material the pinions are made of not because of the OWB. I haven't heard of the P500 having problem OWB, only the old Mini Protos OWB.

I did vote for steel pinion. The aluminum in the Protos 500 pinion is too soft.

I have to be specific I don't have problem with 6mm OWB (i.e. 15T and up). All my problems with OWBs are with stock 13T and 14T which run 4mm OWBs. And it's the soft 4mm shaft that wear out causing 4mm OWBs to slip.
