Any chance you're using a JR/Spektrum high torque servo? I've been having similar issues with 2 different brands of ESC. The local hobby shop was told by Castle Creations that for some reason, JR high-torque servos can draw up to 6 amps when changing direction, which causes the ESC's BEC circuit to shut down briefly. This re-boots your receiver for a second or two and (if you're lucky), the car stops. At the end of a straightaway, the amp draw should be lower at high RPM, so any low voltage issues should happen when you first hit full throttle. My car always seems to shut down at the end of the straight just as I turn in, so Castle's explanation sounds possible. I'm going to try a big capacitor on the receiver this week, and if that fails swap to differend brand of servo.

Does anyone have a good base 17.5 duo1 setup for IIC?

Thanks

Hi

Thanks will change out the servo and also check the capacitor. Am using Futaba 9551 servos. Not sure if there is high amp draw for it.

Just wondering what happens when the BEC cuts-in ? Does the ESC apply auto-braking to slow the car down ?

yup thats what I ment sorry , I thought Muppet was a universal word

I maintain my car perfectly and to sugest something faulty on my car if you knew me would not be a question ...

I cannot test against the others as they dont train so much as me and when they do train I am usually working due to my shifts at work..

As i said the only thing that changed in my car was the speedos softwere so i am thinking that IS the problem , and can 10 other people who are having almost the same problems as me have a bad bearing or a bent tierod or a broken belt or so on ..... after just uploading softwere ???

Hi
I've just bought an RS and was planning to run it with my existing SP V3.0 13.5T motor, however a couple of guiys at are club are telling me not to bother as the RS does not work well with this motor and I need to buy a LRP X12 13.5T to get the best performace. This suprised me as I though the SP motors were pretty good, and with the adjustabiltiy of the RS I should be able to get a pretty good setup.

Has anybody got a SP V3.0 13.5T motor running on a RS / RS Pro that they are happy with, or un happy with?

My ESC will be runing 208 when it's installed

Thanks

I have the 9550 and it is a very similar servo, had no issues like how you describe. Is the ESC getting hot?

Sounds like it will be worth getting it sent in for service if your setup is good for your application.

thanks for the suggestions guys i dont run with push control tried reflashing and reseting have not tried a little drag brakes il give it a try cheers

i now the 3.0 sp runs great with a tekin.
the x 12 just are geting hot with oke power.

I run the SP V3 13.5 motor with my RS and it is just as fast as the X-12, it only lacks a little bit of bottom end compared to the X-12.

I have been running a SP v3 13.5 for about 4 months and it is a good motor with the RS

Allthough to get it quick with v208 i am running MAX timing from 8,xxx to 19,xxx gearing of 6.4 and MAX turbo with a 0.3 delay and the temps are still only 65 dergees C with the Sp motor cooler and fan on the motor

I dont advise you to MAX everything out as i have done but it works for me and that is all I can say

i think you hit the nail on the head,your not suppost to run max timing as it can bog down and i think that is why you are slower
