Hi all,

I'm currently running an LRP Quantum 2 and can't get rid of the glitching problem. The servo runs fine but it's the ESC that's a bit glitchy which in turn makes the motor stutter. This occurs when I'm driving on full power and steering around long sweepers and when I change directions quickly.

Other electrics include:
KO 2343 servo
Sanwa/Airtronics Rx-311 receiver
AMB PT

Now I've heard that the 6V KO servos and the Quantum 2 don't mix too well but has anyone solved the glitching problem? I've tried moving the PT, sheilding the receiver and plugging a power cap into the receiver with no success.

Has anyone had any success? My next step would be to put another shottky on the motor (I have one already) or maybe one of those big power caps onto the speed control?

Has anyone solved this problem?

Any advice would be much appreciated.

Thanks,
Jason

how close is you pt to your servo.

Tony,

Not sure if this is the problem. It was originally on top of the servo but I've moved it to the front bumper - same problem. I've stretched the PT as long as the wires will allow and when I blip the throttle and turn the wheel the same time - same problem again! ARGGGGHHHHH!!!!

I've been careful to try to keep wires from crossing and everything else. I still can't solve it.

what chasis are you runin?

Run the world's kit. If it is your ESC that is causing the glitching (more than likely due to not receiving enough power) this should cure the problem, that is assuming that there is nothing wrong with the QC2.

whats the status of your steering servo wire between the servo and your receiver?

I'm running a Factory Team TC3.

So has anyone had the same problem and had it go away after installing the world kit?

Servo wire's fine. I've tried another servo (same model) and problem's still there.

i ran a tc3. never had a problem with glitching. although i never ran a QC2. i ran a gtx. i put it right by the motor. had the pt right on top of the sevro. the servo was an airtornics digital.also rac 3 caps and 2 shottky diodes on the motor.

QC2 sometimes glitch because KO Propo servo draws a lot of power during use and thus not sufficient enough to power the receiver. QC2 BEC ( I think ) is same or less than LRP V71 which is 1.2A

Also check the size of your com, I know when my coms get small my Q2 really starts to glitch on power making the car feel really tweaked. try changing motors, i think this will help.

get a yokomo noise stopper from speedtech. It gets the job done!

I have had a problem with glitching cause by a bad pot in the servo. Which was causing a short with the reciever.

just get the cap for the reciever, available at any hobby shop and is made by spektrum it will fix all of it.... I run an 8x1 with a Q2 and a KO2123 digital servo and have not had a problem since I installed the power cap

Some people are just too dumb to read.

Ontopic though, i remember i had glitches using the KO 2343 and QC2 in the "Hyper Reactive" throttle profile. As soon i tried other profiles, the glitches stopped.
