it took a dang month but mine came in. So far I'm quite happy with it. Good looks and the magnets are probably stronger than my Trinity certified motors

what does the writing on the rotor shaft say?

another series race in the books.

using a fan on the 2wd ST (13.5 class) and 2wd buggy 17.5 class and some timing changes on the ST (half timing, probably a bit agressive but worked) I got the motor temps to around the 110 degree range.

Managed to TQ and Take the Amain for 2wd buggy and 4wd Buggy. ST unfortunately had breakage issues but still set fast lap with the truck.

All in all these are great motors from what i am seeing, lots of pop. trick is finding that sweet spot relative to timing and gearing.

picked up a 17.5. used my buddies motor testing tools (fantom facts machine and the fantom rotor checker). the resistence numbers were 17.7, 17.8, and 17.7. the rotor was 1657/1654. the motor felt good all day and i don't think it temped higher than 115.

what did you end up with for timing and amp draw?

From the factory on the 17.5 I think it was about 3 amps.

it's not ROAR approved but i assume it's been sent in. ROAR takes forever. it's approved by the two euro federations (BRCA and I forget the other one).

Tested the 8.5T mod motor on the track today. The rotor is super strong that with 30* can timing feels like my old skyrc ares pro 8.5T with 20* can timing. For some reason I'm not able to get the lap times i got with the skyrc, will try dropping some degrees of timing next day. I run on an indoor small tight track, medium grip carpet.

Yeah the rotor is very nice. What class you run this in and you have pics or vids of the track?

Drove these for the first time last night. Carpet track with tighter than usual layout. Set 13.5 and 17.5 to 6amps as a starting point

13.5 in 4wd felt great. Easily as strong as anything I've used before. (trinity, reedy S+, R1 v16). TQ and win

17.5 felt a lot different than the Reedy S+ I was coming from. Tried a couple different gears in practice between 72/26 and 72/28 but it was hard to get clean laps for comparison. Settled on 73/27 for the quals/race. Qualified 2nd and won, but due to consistency, not fast laps.
I think I'm going to drop the timing for the next race and see how it goes.
