Is this the brushless one? It's probably cogging. A better battery (which I would suggest you get immediately) and lower gearing will help, but it's gonna do that. It's just part of the way sensorless brushless motors work.

Have you checked the pinion to spur gear mesh?

yep your motor is cogging. you need a battery that can supply more amperage (lipo) you wont really get 100% performance out of the motor until you run lipos.

I am too, just getting back into the RC world and bought a Redcat Volcano EPX on the web. I didnt realize that batteries were hard to find. Only on the web and Hobby town does not carry them. After runnning it lightly with the original connectors, I switched the 7.2 3000mah , 8.4 5000mah and Volcano to Tamiya connectors. Now it sputters out when I give it full throttle. The first charged on both batteries were at full capacity 3amp/5amp. Not sure if this is the issue. I also noticed a small red button on the esc. Not sure what that does? reset? help. did I do something bonehead here?

Use Dean connectors, tamiya connectors are terrible

Hobbyking and Hobbypartz have all your LIPO battery and LIPO Balance charger needs

NiMh batteries are not designed to handle brushless motors

I am assuming you have the brushless version, do you?

It is a brushless motor, and I noticed that that there is a red light blinking on the ESC when the motor cuts out. I turn the ESC off then on and it resets something, then it runs fine. after a while, the light starts to blink again. Should press that red button on the ESC? Does that "sync" something so that it will stop the Volacno from sputtering? Is that red button a self distruct explosion devise? (just kidding) But what does that red button do. Thanks for reponding to my questions earlier. I wasnt sure if anyone was still active on this thread.

the blinking red light, and then motor power cutting off is a feature nessesary for lipo batteries.

It is not needed when running nimh batts.

Most likely, your nimh pack is weak or your charger isnt charging it very well.

Upgrade to a better battery and charger (lipo recommended) and you wont have this problem. A 2s lipo pack will also add more power/runtime and top speed to the volcano.

I run a skylipo 2s 5000mah pack in my volcano. 25+ minutes of runtime and lots better speed over any nimh pack.
