I switched back to Trinity after I had 2 Reedys 17.5 smoke for no reason. Taking out 2 ESCs and a battery.

Here is the video of my killshot letting out the magic smoke.
The car comes to a stop around 2:10 and the corner worker runs for it.

The mach 2 is very fast at 30-32deg timing and 3,8 - 3,7. If your more of a beginner to intermediate driver stick with the 4.0-4.1. Make sure you use a fan.

It ran fine the first three days and I went down a tooth on its final day.

The insulator melted on one side.

I have switched back to d3.5 after 2 killshot burnt.
I am regret to say the d3.5 is still un-beatable and can survive under higher temp even it is 20g heavier ...

Having an odd issue with my new KillShot 21.5 motor. It's in a F1 car with an orion r10 pro esc.

Basically if I pull on full throttle from a stand still it takes about 1 second to rev up. Almost like for that first second it acts like it is on 10% throttle. Thinking it is a sensor board. Have a new 17.5 KillShot that is due to go into my TC so I may do a sensor board swap to test.

Not so sure about that. Certainly wasn't the problem in my case. My motor was coming off at no higher than maybe 130*F or so the night it decided to blow up and take out my ESC in the process. Never again.

Now that I've read every single post here, I'm worried that the same poof will happen to my killshots LOL. When I started checking this thread, I was just wanting to find out WHAT THE THINNER SHAFT DOES(modified) and WHAT THICKER ROTOR DOES. Apparently both either give high torque or high speed, correct?
Anyway, so far my motors are fine after about 2 hours of running each.
17.5: HT/HT FDR:3.49 MOTOR TEMP: 145 Timing: 55 Track: indoor small&tight carpet Temp: 60ish nowdays
21.5: RPM/BP FDR: 3.0 MOTOR TEMP: 100 TIMING: 40(STOCK) TRACK: outdoor large asphalt with long straight TRACK TEMP: 100-130F
Another guy at the asphalt track burnt his 17.5 though. Not sure of his gear ratio. He wasn't sure of that either when I asked LOL. Anyway, did anybody find any magic solution to that yet??

The failures aren't related to overgearing or overtemping or any other kind of mistreatment. Mine was running only 125*F (at most) with a mild gear. All other stories I've heard of Killshot failures have been in similar situations. Personally, I wouldn't even consider running a Killshot again. My ESCs are too valuable to me and I won't risk melting another one.

Yeah I read your posts Tommy. Well both my motors are virtually brand new LOL. I guess I'll just have to be monitoring real close.
So what are you running nowdays Tommy?
