When I bought my Axe I was a bit disappointed with the unreasonable short time of 5 minutes using the stock green batteries. After doing some reasearch, I made the jump to LiPo technology and purchased (2) Thunder Power 1320 11.1 v 3 cell batteries. Along with those, I bought the Accu-Cycle Elite charger so I could charge both my LiPo's and my stock green peas. I get about 13 mins of solid filght time now and the irony is that once I was complaining about not having enough time, now I'm paranoid about running too long for fear of buring out my motors. After a flight on the green peas, the motor temp is around 126. After a spin with the LiPo's, my main motor is about 158. That's the highest it's ever been. That tail motor gets up to about 99. What's the safe temp range on the electric motors.

I'm diving in head first with these Heli's and these have me hooked far worse than my rc car. All I wanna do is Fly, fly fly!!

I am wonering the same question. I have the MegaPower 1350 Li-Po battery and I ran it for 16min back to back with my two batteries. I think I burned out my motor because it started smoking. I shut it down and unplugged the battery. After it cooled, I tried to plug the battery (MP 1350) back in and the e-board sparked and displayed a small candle size firel I blew it out and that was it for that bird. I have another Axe CP now and I'm afraid of repeating. I don't know if it was caused by the battery. being a 1350 or something else shorted out. On a side note, I put the battery back into the charger and it charged up alright. I had also placed the stock battery back in the Axe for a second and noticed one of my sevos lighting up.

Is a 1350 battery to much power for the Axe motor or did I run it to long? How long do the motors usually last on these units? As you can see I'm still new at all this.

....on fire!?! Hope that doesn't happen to me. I run (2) green peas back to back or I run (1) LiPo only then do a cool down period. Sometimes after a Lipo run, I use a small hairdryer I have set on cool air just to blow some air over the motor and heat sink. The tail motor doesn't worry me as much because I haven't seen the temperature of it get above 100. I'm gonna experiment with some different heat sink types on a new main motor including the stock heat sink to make a hybrid that will fit in the frame. Like using heat sink compound to stick a modified sink on each side of the motor. It might stick out of the frame a bit but the surface area might give it a cooling boost. My friend has a boat and he made a heat sink that holds a piece of dry ice in it which really keeps his motors from getting ridiculously hot. As we all know when it evaporates, there's no residue left to harm the motor.


May the Force be with Ya'll,
