Speed Passion Reventon-R Problems

[Muzzie]

Please could anyone give me some advice as I’ve been having a few issues with my new SP Reventon R ESC and SP V3 7.5t motor set-up.

I installed this into my Cougar SV using the kit standard spur gear and 23t pinion. I’ve run the car indoors for 3 week at my local club with no issues and was really impressed with its performance . However, 2 weeks ago I ran at the east mid regional’s (West Bridgford) and in the first heat after two rounds of practice, the car stopped. My first thought was the thermal protection had cut in because it was a hot day. I checked the temperatures ESC = 56◦C and Motor 62◦C, all in normal parameters. In round two, the car seemed great until the last lap, where the car, didn’t stop but acted like the lipo was flat. Again, I took the car off the track, check the temperature and lipo battery (SP 6200mah 65c 2 month old) all was fine, I switched the ESC on and off and the car burst into life again. To try in fix the problem, I re-binded the receiver and ESC to the radio. This seemed to work and raced the rest of the day problem free.

After a frustrating day, I thought it might be worth updating the firmware to see if that would solve the glitch. After hours of messing about, it was done. I ran the car last night at my local club and for an hour of hard practice the car was faultless. However, again in round 1 the car started to glitch, but this time, when I released the throttle the car would surge forward on its own. (For INFO I have a power cap fitted). Again, I re-binded and all was well.

This is start to really grind my gears and I’m not sure what else to do apart from return the ESC to the shop, but this will mean I will be without a car for about a month and I think it would be impossible to diagnose.

Any ideas?

Have you had any luck with this?? I have the exact same problem!

My mate runs the same and his runs perfectly fine!

Are you running lipo cut off. It my be as you are accelerating the lipo may be briefly dropping below your settings. Thus sending the ecs into sensorless mode, ie like the lipo is flat.

Might be a worth an email or call to Schumacher if its a common problem. They will be able to help

I spoke to schumacher and speed passion and both have said its a faulty motor no doubts!

I have sent mine for repair today so fingers crossed it solves the problem.
