So I was out in my man cave working on my b4. And I had a genius idea to move my esc center line for giggles this weekend. So I rewired my motor leads and soldered them up. After reconnecting my motor, I preceded to make sure it was all hooked up well and power up my buggy and gave it a little gas...... Then I immediately heard a thud......and the result is below. So I am no longer racing this weekend. As my motor is in pieces. Anyone ever wondered what an exploding rotor looks like? Bam. And it was never run over 130 deg. Anyone wanna bet my viper esc is dead? Anyone think my slator or sensor can be salvaged? I am not sure i can get all the tiny rotor pieces out of the slator.....yippy.
HOLY CRAP THAT'S AN IMPRESIVE FAILURE!
I guess I've been lucky so far. The only impressive failure I've had was when I pierced a lipo & turned it into a giant jumping jack... in my kitchen... at 2 in the morning... Setting off all the smoke alarms in the house... & waking up the neighbors

local hobby shop got a proline b4.2 body in... so painted it up after racing...
really enjoying the yellow on the track. its "my take" on a cherry-esk body.
mostly wanted to try out the new proline wing.

Me? lol, nah. That would be funny is rotors exploded if you crossed A and B. They would be dying everywhere. I had heard of the older rotors coming apart. heat was the cause before. I was using this motor outdoors from jan to match. It stay around 100deg because of the cool outdoor temps. The motor was like 2 months old and not even run every weekend.

ir was hooked to the tranny and tires were on it. It was not a full load and I never went past 1/3ish throttle. That was my original thought as well. Maybe even the cause. If so, I am the post child for never bench testing a motor, lol.

I had a lrp do the same thing. I will blip now just to make sure everything is armed but will not hold for any length of time.

I probably held the throttle for maybe 1-2 seconds. Maybe that is all it takes. oh well. I will just cheer on the kido this weekend and take some practice laps in her car to at least get some track time.

I did the same thing after returning from a long hiatus from R/C, a time from which my last motor had brushes.
Just a couple quick pulls on the trigger and "thud!". Then I read that not supposed to run motor unloaded like that. Lesson learned.

Always wondered what a litter of baby Reedy's would look like, are they pure bred?

he, but now we all know what a rotor looks like with no magnet, lol. I have 3-4 brushed motors left over and a comm lathe, lol. I am half tempted to pick up a cheap brushed esc. That can do 10 turn. I have 2x QC2's I sold for $15 each.....wish i had kept them, lol. Brushless motors are still a little scarey. I had a 13.5 blow a sensor board a couple months ago and it took out the esc with it. It seems like when the esc or motor goes it like to take the other with it. I am glad my viper esc survived.

Some footage of Ryan Cavalieri and his B4.2 I took while at WCRC this January, he was running the red bodies (I assume because of the AKA deal).
