Car glitching, indoor racing

[wookieewonder]

Hello I'm after some help on solving glitching problems. Car has been fine racing outdoor all season untill moving indoors were it has a slight intermitant glitching problem. Every few laps the throttle will stay on for a fraction of a second too long or the steering will cut out just momentary. It only seemeds to happen at indoor venues. Outdoor meetings it's fine and on the bench in my house / down the local car park for a test run it never glitches , not even at a large range .

I've fitted a power cap to the rx, this has stopped the steering cutting . Have lowered the esc punch too from max (9) to 7 seemed to help a bit. It seems to happen the most after a straight on the track. I'm on 2.4gh (flysky fs-gt3c) trackstar 120a, turnigy digital brushless servo , trackstar 8.5t,

Are rc cars more prone to glitching/ radio interference when racing indoors? Thanks you for any advice

Yes they are more likely to glitch. Power cables, metal structures, lights etc.

Also more likely to notice, narrower track, tighter corners, more grip (sometimes)

Had similar issues with my car and power cap sorted mine, what batterys are you using

We had this recently with a guy at our club.
We tried fitting a power capacitor and it didn't solve it.
It turned out to be that he had fitted a new high power digital brushless servo. When he changed back to the kit servo the problem went away.
He was running a turnigy esc and motor.
He now has a Hobbywing V2.1 and this runs fine with the brushless servo.

Good luck with solving your problem.

Have you tried lowering your battery cutoff down to 2.6/2.8 volts per cell as sometime when racing indoor the higher speeds and traction put more strain on the electrics compared to outdoor and you may be having momentary drops in voltage which causes the issues (the batteries will be ok at these settings as they will still fail safe and recover above 3 volts)

Thanks for the responses guys, much appreciated. The batterys i'm using are turnigy nano a spec 4200 shorty 65-130c.

The servo is my new piece of kit, I've checked with a volt meter the amp draw of an old slow servo - 100mA . New digital servo , 1.75 amps draw!! So they are def power hungry, and this is operating it on a bench with wheels off the ground. Maybe my esc 3amp bec can't handle it with the punch turned up to max on high grip carpet / tight start / stop track. Think lowering punch setting and more sensible boost start rpm are the way to go. Will also try lowering the low voltage cut off from 3.2v to 3v or off to see if it helps , I never take much charge out of a pack during a 5 min heat. Thanks again
