Hey all looking for some advice,
I have blown up 3 motors now with the Felony and its stock with the speed gear 27T.

By blown up i mean in the middle of a run it will all of a sudden stop and clog in place and not move forward or backwards like its lost a winding or something.

I don't understand why i am going through motors.

Thanks.
 
The pen is blue, and you can't bash with the speed gearing on factory electronics. It's meant for one (check temps) or two (upgraded fans) full speed runs and ample cool down period.
 
Does the motor get hot enough to roast a marshmallow before dieing?
Does the car roll freely without the motor in? How about with it in? How's your pinion/spur mesh set?
Yes to all of the above, thats what doesn't make sense, i have monster fans, i do a run and let it cool, i have active temp sensors to monitor temps

what temps are you seeing? the inside of the can is always at least like 20f hotter or so I've been told.
 
Honestly on stock gearing and a hot day if you go full trigger fully charged to dead you'll also smoke ESC's and prolly motors "personally doing this on a stock setup ive smoked 2 esc's". These cars are high strung out of the box. I consider it necessary to update the motor/esc immediately now. Dual motor, dual ESC and 4s to each esc is literally the same speed and fun as with the speed pinion on a stock setup. But you can beat it charged to dead all day long. Or get a single motor setup thats huge. Just some suggestions. I have many different motor/esc combos in my cars. Two 4s packs or two 6s packs on Dual stock motor/esc's, another is 6s Max6 4985, and lastly a 12s Max5 56118sd. All are combos that are bullet proof.

Again in stock form they cannot be bashed bashed!! Even with the stock pinion and fans equipped. Generally its your ESC that goes first, but i've dropped magnets off the rotor on stock setups on an arrma. Blowing motors constantly is odd, but also a 27t gear is giant hahaha.

Funny edit:
I know i just posted this in my other thread but its very justified here.... This is what you did for gearing lolol... And here you can see stock gears compared to a 27t lolol for gear comparison....

You’re running on blacktop/concrete, right? Not in the grass or something? @RedPen , it’s important to note that “one run” is not bashing for as long as your LiPo lasts. A “run” is a speed run that takes seconds. Then a cool down.
Take your speed pinion off and put your gearing back to stock. The stock pinion is 16t. That’s for normal use! All bashing use with the stock system. You MIGHT get away with a 17 or 18t, but you must monitor your temps, and if you’re running 6s then you need to do it before you hit LVC on your high MAh LiPo. Or you can easily roast motor #4. The speed pinion is just for speed runs. One at a time. Maybe two on a cool day. Again, these runs only take seconds, so heat doesn’t build over time, and even then needs to cool down.

And if your motor is getting hot enough to roast marshmallows all the time (dude!!!) then your temperature sensor must not be working. What kind did you install? What kind of temps are you seeing? You mentioned frying three motors in a row but didn’t mention the temperatures? The stock electronics only protect the ESC for thermal shutdown, they won’t keep you from frying your motor. Buy an infrared temp gun for cheap and check the motor temps in the middle of your pack at the least or sooner until you know what kind of temps you are building. Cool off if it’s 180° or so. That’s Fahrenheit, man. If it hits 200° it’s dangerously close to roasting for good, and if you hit those temps regularly the life is shortened a lot.

Like others said above, if you want to run it to the extreme for long durations many here will be happy to help you spend 💰💰💰 for a system that can handle it. Your stock pinion (16t) and paying attention to the motor temperatures before your marshmallow is finished roasting is key. 😊

Two 4s packs or two 6s packs on Dual stock motor/esc's, another is 6s Max6 4985, and lastly a 12s Max5 56118sd. All are combos that are bullet proof.
I don’t think it’s a good idea at all to say this until he is a lot more experienced in not roasting motors. 😊 When I was a noob I came very close to frying my Max6 system in my Mojave. I think I was running a 19t pinion.

In the neighborhood of 160-180 after a few runs. In Arizona its usually about 115 during the day so it runs hot.

This is some great info thanks Dan!
For the temp setup checkout my other thread: https://www.arrmaforum.com/threads/...control-system-abs-tractioncontrol-esc.72510/

As for a run, yes im meaning a single speed run down the street. The 27T is the 'speed gear' that came in the box and it mostly does fine for the runs but it seems like the windings keep shorting probably from high peak temps and heavy draw.

For my batts i have 2x Zeee 9000mAh 100c 6s and 4x Zeee 7000mAh 120c 3s so i usually alternate each run between them.

I just now got the joke 'The pen is blue' **Face palm

Please define “a few runs.”
I have no explanation for that other than those aren’t even close to the actual motor temps. You’re definitely not frying motors that are 160-180° after a few runs. If those runs are done in 115° ambient temperatures then no way at all those are accurate temperatures.
I’d toss those “active temperature sensors” because it sure sounds like they just cost you 3 motors. Monitor your temps with an IR temp gun. Often. Like every 5 minutes in those kind of hot days until you really have a very good sense of what your motor is running at.

if you're at 180 on the temp reading you're definitely burning the motors up. I mean there is no other explanation as to why you killed 3 motors. Especially with a speed pinion and 115f ambient. I don't even take my rigs outside in 90f but that's mainly because I'd melt. I feel bad for you arizona guys tbh, you're definitely nuts for running speed pinion in arizona at all tbh :ROFLMAO:

You def need to upgrade electronics and you need some seriously good fans. 12v server fans on a tiny 4s lipo or something like

https://www.radiocontrolpower.com/p...-bracket-with-40x28-fans-aluminum-mesh-covers

which blows the same amount of air as above but can be plugged into the rx. I'm not sure what monster fans you have but if it's not on a separate lipo or the ones I linked I bet money they aren't good enough.

I don't even know how i'd rc in arizona, winter only? :eek:

I have this two pack on the motor, a single on the ESC and they all run on a 3s lipo

180° is too low for reality given the circumstances and not enough to continually burn up motors if it’s a real temperature. His temps should be well over 200°, probably much higher. That’s why I think his “active temp sensors” are either junk or mounted in such a way he’s getting incorrect readings. There’s no way he’s running 180° motor temps with a 27t pinion in 110°+ ambient temperatures for multiple packs. He’s running way higher than that.
 
I think 2 speed passes with stock electronics with the speed gear is good enough I mean it says on manual the pinion baggy not for long use it bash driving etc
