Green rotor just installed, i have to replace a 0.5 mm shim by a 0.2 mm to have a good clearance.
Not a big difference when i m turning the rotor with my hand.

How careful do you have to be gearing and timing up with a fan blowing back onto the motor?
I was surprised how much cooler my TP was running first time out running with a cooling fan, it seemed to keep temps a lot lower, though if you unplug the fan and recheck temp after the run, it instantly seems to rise as much as 10C.
This had me a little concerned you could cook or be overheating and not realize cause the fan is cooling it back down so fast by the time you get to temp it?

I would keep the motor timing below 30deg and don't max out your ESC, take it up in stages.

I only unplugged it to see just how much heat soak the fan was preventing, and it turned out to be more than I expected, to the point I worry about thermal load the motor will see internally without me ever seeing or feeling it.
All this was zero ESC timing, pretesting on my 10.5 before I fit my new 17.5 and start dialing that in for a big event (never run 17.5 before), with the 10.5 though at one point I had it up to 40deg timing on the can, still running cool with the fan being on it, though also a cold night.

TP 17.5
Does anyone know the spec (ie KV and RPM) for this motor? I looked at their web site but it doesn't say.

The blinky I've seen to seem to run the timing around 35deg, and said the green rotor made a big difference in blinky.

Yeah, I wired up the fan right from the start directly off the battery source, but I put a plug on it for testing purpose, but as long as the battery stays plugged in the fan can always stay on.

They don't seem to get as hot as a lot of others, especially the LRP's etc.
