Broken spur this morning, uneven gear mesh, investigate. Hope I didn't bend motor shaft.Getting a 17 tooth gear soon,going for the top of the speed chart. Standing on a hill top at the local high School I can run up to near a 1/8 mile distance with 1/2 mile available. (Yes I do off road an bash too,but the how far an fast thing is impressive too.)
Soon as I get back home,I can take pic. Running errands. Hopefully didn't bend motor shaft,had uneven mesh last quick look.What?
That is so weird, I have seen broken pinion but spur just like that. Try to take pictures and upload.
Use macro settings when taking them and show the place you were driving. It will be a first to see a broken spur gear, not even on 5th scale, the clutch bell, bearings, pinion, everything goes south, but never seen such thing happen. And to be a 5mm shaft, if it did happen you must have been bashing it hard.
I have been having fun w my SC Blackout Pro truck, dialing the suspension running it on a upgraded Goolrc 3660kv. It is true, same specs as the Redcat motor, but the new one has 5mm shaft and much longer can. Has tons of torque, need to put a 17t or higher, still running 120F doing full speed passes in a small track near my house. On 3S is stupid fast and a 15t its just spinning all the way to half throttle.

Went red locker,dryer couple days,we'll be giving her a go again,hope to come home in one piece.Update later.Soon as I get back home,I can take pic. Running errands. Hopefully didn't bend motor shaft,had uneven mesh last quick look.
View attachment 9312rebuilt diff just in case this time,gear mesh a hair tighter at one spot in rotation check.time well tell.Hope hot racing stand off isn't a problem with mesh or alignment.
Rebuilt an ran 15t ok untill it slid off motor.probably not going 17 t untill I can keep it going at 15tooth.
Have also heard of trying to file or find yourself a way to make set screw flat on end before red loctited. I'll keep posted on how it goes.You have had better luck than me.
On mine I used red threadlocker, $10.00 for a little bottle. It did not do a thing. At least for me, it is NOT that the nut gets loose, its that under heat and stress, metal expands and slides out. Thats on my rc, similar to when removing ball bearings from bottom ends nitro engines.
To me, the tolerances of the pinion gear ARRMA brand is too much gap, should be tighter so under heat they don't slide out. Its hit or miss, I got tired of the slide out deal and ended doing the notch.
Its good you were able to save the motor and no damage to the shaft.
Orange teckno?Whats the part number on the springs that your running??
