I have a Night Ranger 3D since may 2008. I am not a great pilot, but I hadn't had any major crash with it. (I have learned on the Ocean Rescue and sims) In September, I have done the brushless conversion, and liked it. I had no problem with installation, and it operated very well with my casual type of flying.

This weekend, I was holding the heli with one hand, and checking how much lift it had. When I've reached 50% throttle, i flipped the 3d switch. The motor has stopped like if I had put brakes on it, and became extremely hot. The battery (Lipo 3s 11.1 that I've got with a second hand NR3D that came already with a Lipo.) and ESC went very hot, too. After all was cooled down, I have carefully given a try. On power up, the gyro initiates, servos move, and I hear the usual noise from the ESC that let me know that everything is okay. When I apply throttle, the motor stops spinning at about 10% throttle and I hear a sound that is like a bad adjusted gear mesh, that seems to come from the ESC.


Have you ever encountered a situation like this? Can you help me find what happened? It's my first BIG problem with a Venom product. I have another stock NR3D that works very fine, two Ocean Rescue, and one Nr3D Micro, and am very satisfied with these helis.

Please tell me there is someting not too much expensive to do to solve my problem. I hope I won't end up in needing to buy all electronics...


Thank you for reading and responding

Venom all the way !!

Did you cut the recommended cooling holes in the canopy/windshield?

Also, if you run too much pitch, the motor will get hot.

I have had my ESC shut down in flight. I was using batteries with a lower "C" rating than I should, and the ESC (it is an older one with a hard cut-off) shut the motor down coming out of a roll.

brushless NR3D

Hi,
My canopy had venting holes, heat sink were installed. I was using the new stock Lipo batteries they provide with new NR3D's. My carbon blades are shorter and wider than stocks. My brushless setup is the original from Venom. The heli has just been powered up. I have brought motor to mid throttle, and when I have flipped the 3d switch, (for the first time since the conversion) it just tried to suddenly spin to the other way. Then, motor and ESC went very hot.

The other day, I was thinking of this heli, and tried something:
I have removed the blades, and powered it up. Like before, the motor was "complaining" and wasn't sure which way it was supposed to turn. I have applied more throttle, and suddenly, it began to spin the right way! I did some accelerating tests, and it seemed OK, So I have reinstalled blades, and was able to fly it!!

But I still don't know why I had the 3d switch problem, and have the fear of flipping the switch again. I don't do aeobatics, but I 'd like to have a fully functionnal heli,for the day I will be ready...

Thank you for your reply

Venom all the way !!

I would definetly contact Venom. They have very good customer support.

If it is trying to run backwards when the Idle Up switch is thrown, something is wrong electronically that I imagine the end user cannot fix.
