LRP SXX TC stuttering at low speed
 

I've just installed my LRP SXX TC with my 6.5t Losi motor. At slow speeds it sounds like it is cogging slightly or like the transmission is clunky. Anybody know what it could be? It has a new capacitor and the sensor lead is fine.

is it a version 2? if so they dont work with 40 meg ko radio

No it's a version 1 and I'm using a spectrum DX3S

have you tried changing your sensor lead? :eh?:

i only ask cos i had one that looked fine but was broken internally,
have you also checked the settings incase it has defaulted to a brushed setting :)

I've tried it without the sensor lead and the motor didn't turn at all so I doubt it is the sensor lead. Also it doesn't have a brushed setting.

Have a chat with Martin (Tisher) He's been having some problems too, Sounds very similar. He seems to think its his motor thats on its way out.

Hes got an X12 5.5t, What motor are you running?

Are you sure its the ESC? have you not got another to test?

It won't work at all without the sensor lead, you need to have that installed!

Definitely replace your current sensor lead with a new one. Treat the sensor lead as a perishable item. They are only a few quid.

The sensor lead was fine with the other speedo that I have replaced with the LRP. I tried it with and without the sensor lead to see if was the sensor lead causing the problem but it wasn't.

Is this the speedo you bought off ebay for £40?

Josh I have been having problems with mine over the last few weeks.
my one starts juttering like mad after about 3to5mins of racing depending on how warm my motor is before I start but when mine dos it the esc s led lights flicker with the juttering I am putting it down to my x12 thurmalling as the colder it is before I start the longer it takes for the problem to show

Yup :woot:

The leds on my speedo don't indicate anything weird and the stuttering goes away past about half throttle and it happens whatever the temp of the motor.

And now you know why it was so cheap.

Well he said that it was in perfect working condition and he was selling it due to sponsorship. Also the starting price was £30 but there was only one other person bidding on it that's why it went so cheap. The original power cap had been removed because he said that he damaged to one on his other speedo and the one from the lrp was the only one he had spare but i have used a very high quality cap to replace it so that shouldn't be the issue.

Try a spektrum power cap in the reciver that will sort it if not get a proper lrp power cap

I've tried the spectrum cap and it made no difference. The power cap that I am using is (I think) the same or slightly better than the stock LRP cap.

Is there a current Limiter on this speedo?had a similar issue with my kinetic and it turned out I had the current limited to low.

Its on the stock setting which according to the manual has no current limit.

make sure the bits in the plug are all fitting properly in the reciever,i had a similar problem and it was due to them not fitting properly,try wiggling it to see if it goes away
