technical glitch
 

Hello,

I've recently had a technical glitch in which during the later part of a 5 min race. (1/10th buggies) when steering, the throttle would twitch. I picked the car up and whilst only touching the steering, the throttle would twitch. I swapped the speedo and the problem went away so it must be the speedo but wondered if anyone had experienced anything similar?

If so did you find out what was wrong?

Cheers

which speedo?
which capacitor ?

could do with more info

was it a one off incident ?
had you recently moved/changed any components
what electrics are you using?

i had a silly one a while ago where esc and servo plugs were back -to back in rx sockets and once or twice the pins must have bridged/shorted intermittently cause all sorts of weird goings on

not saying these are your problems but more info would deffo be helpful

Yeah apologies for the lack of info guys.

The car is a Hoboa H2.

I'm running a lrp sphere tc spec, savox low profile servo, futaba 40 mhz reciever, mrt transponder, dualsky 8.5.

It did it in every race for two weeks, so 8 heats in total, then i changed the speedo and it stopped. It did start after I moved the speedo from on top of the lipos to the chassis so that could be a cause but i'm not sure why and if it is that then why is it fine with a different speedo?

when you have glitches under steering servo movement its usally a problem with the power receiver power supply. Thats why I asked about the capacitor. The LRP has one stock I hope you use it and it works and doesnt have a bad cable?
This is my No 1 bet what it might be. Savöx are a bit power hungry so this might be the problem when running on high grip surface where the servo has to work more and the transponder pulls some energy too.
There are some capacitors that can be plugged in the receiver (spektrum for example but you can solder your own one if you want to get it cheaper), this is a easy way to make sure the receiver has always enough power.
There can still be a problem with the receiver, speedo or servo.

Thanks moose that all sounds very plausable. A fiend of mine suggested the same thing and he lent me a cap to plug into my receiver, it didn't help but then that may be because it's not the right type of receiver to be able to do that?

Anyway, i'm putting the speedo back into another car to trial it and see if I can find the answer.

I'll let you know if i get it sorted.
