I would still add fans though if you dont already have them

Gearing down is certainly going to be cheap. Although I can return my 3S batteries still (bought them from Amazon), so going to 2S might be a cheaper start.PC fan in and of itself isnt going to fix the issue. Fans are nice but they put in most of their work when the kit stops moving. Id trying gearing down first, then going to 2S if you can't gear down low enough. Going 2S you may even be able to gear back up a bit afterward if motor is running cool.
2S lipos are pretty cheap also. Id just keep the 3S and get a couple of 2S and then you can go back and forth depending on what surface you're running on? Just a thoughtGearing down is certainly going to be cheap. Although I can return my 3S batteries still (bought them from Amazon), so going to 2S might be a cheaper start.
It has 3 very tiny ones, maybe an inch square each or so, two on the motor (with a small additional heatsink), and one on the ESC. But I think I'll add the PC fan to start. It's pretty lightweight, but I'll probably have to use steel to mount it because that's all I have access to right now. The mounting will probably be heavier than the fan itself, lol.I would still add fans though if you dont already have them
Do you have a 5V PC fan? If I remember correctly generally 80mm PC fans run off of 12V so unless you gonna run them straight from the 3S battery then your plan may not workIt has 3 very tiny ones, maybe an inch square each or so, two on the motor (with a small additional heatsink), and one on the ESC.

Why wouldn't I run it straight from the battery? That's what I was planning on.Do you have a 5V PC fan? If I remember correctly generally 80mm PC fans run off of 12V so unless you gonna run them straight from the 3S battery then your plan may not work
If I'm running a 2S, I shouldn't need it (so I may make it easy to remove), and with a 3S I'll just plug into the balance leads. And a 2S will still run a computer fan OK, just much lower RPM than otherwise.Well if you're running a 3S Lipo you could, it would just be harder to hook up than wiring it to the RX but if you're running 2S lipos you wont have enough power to ran the fan properly, if at all.
As I said, fans are mostly there just to cool the motors when there is no airflow going through the body. You can trying the training mode trick and see if that works otherwise just gear it down and/or switch to 2S lipo.Well I just remembered that the ESC has a "training mode" which uses 50% max throttle. I just did some testing, and a 3S at 50% throttle is only a *little* slower than a 2S at full power, and it would probably give me the longest runtime overall. Also, I tried the PC fan, doesn't do enough. It buys me more time and it does cool down faster once thermal shut down initiates, but it's just not enough. I'm willing to bet that a 2S, or 3S in training mode, would not overheat the motor/ESC unless I'm running in 100F (38C) degree heat.
What do you mean "smaller?" It's a Stampede 4x4 VXL, a high-end 1/10th.Yeah most of the smaller kits that say 2 or 3S are really more for 2S theyre just technically capable of 3S. Hows it doing now on 2S?
Mine had a defective motor, brand new. Didn't smoke until I plugged in a 3s. Got a warranty motor, changed it out, good as new, because it was.I have a Stampede 4x4 VXL, with several metal upgrades. I got it in a trade. Mip axles, aluminum hubs, metal swing arms. When I run it on road with 3S it seems to do fine, but when I'm running in dirt/grass for a few minutes I hit thermal shut down very fast. I know I could get a smaller pinion gear, or I could switch to 2S when I'm in grass, but are there better ways? It already has ESC and motor fans. Should I stick a 120mm PC fan in there too? Lol. I don't really want to spend the money to upgrade the ESC and/or motor. I talked to the guy I got the RC from and he recommended lowering the gearing and using 2S, and only doing 3S for occasional fun runs. What do you all think?
Mine is old, before 2.4Ghz TQ. but still does really well for its age, and at least its thermal shut down works still. I think it's the ESC and not the motor but I'm not sure.Mine had a defective motor, brand new. Didn't smoke until I plugged in a 3s. Got a warranty motor, changed it out, good as new, because it was.
By smaller I just meant the kits that only run the smaller 2S or 3S lipos. I wasn't referring to the physical size.What do you mean "smaller?" It's a Stampede 4x4 VXL, a high-end 1/10th.
