I may do that to the Sonic, she doesn't need anything faster then that anyhow. So at what point does a motor need to be retired? any obvious signs? I recall reading somewhere about the magnets weakening with age or something like that?
Third chassis, nice! So you now have 3 supastox and Stan has 2 right?
If anyone comes across a used supastox for a decent price and doesn't want it let me know! I haven't bought a kit yet... try'n to do this on the cheap.

... Let me know how much you want for it if your selling it. I don't need the body, I want to try the Protoform.

I was thinking about setting rollout to 75mm and adding 1 timing mark at a time. I have the motor checker with, but even with a slave I'm not sure I'm getting real results when I tune the motor for 1S. I would think efficiency is efficiency at reduced input voltage. I'm replacing my Z3R as I'm trying to prove a point about cheap club racing.
The Reedy was better across the run, but initially I over-geared it at 70mm rollout. When I realised it was not revving out on the straight and dropped the ratio to 65mm rollout, it was better all round.
Every motor/timing combination is different, but I feel that 75mm is too high on this car. Taking the weight and the inefficient suspension into account (there's more wheel scrub and you have to slow into the turns as the car is more inclined to rollover in sharp direction changes) a lower rollout allowing the motor to rev and pick up speed quickly was faster round the lap. YMMV. HTH

I ran a Dynamite and Reedy Sonic Mach II in mine. The Dynamite was on about 30deg at 68mm rollout and the Reedy on 35 deg with 65mm rollout.

Not much I don't like about the car actually. I value the simplicity and durability.
