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?

The temp rising is where the heat soaks through the can. To help dissapate it I would wire a fan into the receiver or main power wires so it stays on.

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

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.

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.

Default 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.

I've seen a few guys run the motor repeatedly in the 80degC range, but I get nervous if mine get's into the 70's.
They don't seem to get as hot as a lot of others, especially the LRP's etc.

Can anyone say if I may need to gear any lower than a 3.47 FDR with 17.5 zero boost?, having zero experience with 17.5 I have no clue if I'll need to buy anything bigger than the 38 tooth pinion my current selection goes up to?.

Possibly, the guys at an indoor club I go to run 13.5 blinky (30m*16m) and are geared around 4.5fdr
