servo make esc glitch
 

any one know how to make the servo not glitch the esc. i know it not the servo and it not the receiver. it the esc that doing the glitch but every time i turn the servo it make the truck glitch forward. and could this be from old wires that go to the receiver from the esc. (no clue). esc give good power to the motor i just dont think it get good power to the esc. any one can help in any way.

What kind of servo reciever and esc would help

The ESC gets its power form the battery, not the RX. Sounds like your receiver has a short in it that causes a jolt in the position signal for ESC when the servo initiates movement. What type of RX and how old? How well has it been treated?

What type of chassis is this set-up intalled in? If it is Carbon-Fiber, or even carbon reinforced, it may be power wire contact or even antenna contact with the chassis...

ok i put the lipo on the esc and a receiver lipo on the receiver with 7volt reg on it (so 2 lipo) and it work vary well. every thing is new but the esc and it and lrp spear comp. receiver is an fhss-3 airtronics and the the chasie is graphite but i hold everthing up in the air and it still dose it.

i know for an fact it the esc cuz i use 3 type of servo and two controler and receiver. iam thinking the wires in the esc that go to the receiver are not good but would that do that. and if i run two servo with no esc it work good.

In an Electric car the Reciever and Servo are powered by the bec (Battery Elimination Circuit) provided by the ESC, usually at 6v or so

Servos that draw too much current make the bec voltage drop and cause the glitching you are talking about

You have 3 options to fix it

1. Run a seperate power supply for your reciever
2. Add a glitch buster capacitor, they cost a few dollars
3. Add an external bec

Options 1 and 3 require you to disable the esc's internal bec, done by removing the red wire between esc and reciever

Try option 2 first, if that does not fix the issue try option 3

Option 1 is messy

Cheers

Sounds like it could be the BEC in the ESC glitching. The answer to that is either send it in for repair, buy an external BEC which you route from the battery directly to the RX bipassing the ESC (be sure to disconnect the red wire on the ESC so the RX doesn't get 2 different voltage inputs), or buy a new RX. Like you said, sounds like the RX is okay if it runs fine with battery and two servos(as long as one of them is the same servo you seem to have troubles with).

What type of servo is it?

The servo is just drawing too much power. When this happens (especially with Spektrum), they loose signal for a second until it rebinds.

Just install a CC BEC or you can try a cap on the receiver.

For servos that draw high amperage you should look into high discharge Lipo rx packs like this one: http://www3.towerhobbies.com/cgi-bin...4&I=LXSFS7&P=K

Running one of these with a cap inline with eliminate any possibility for feedback glitching. THe problem with too many rx batteries on the market is that they have a very LOW discarge rate potential in the 1-2amp range. The new ones that are able to discarge at 10-12amps and higher are the way to go.

Why would you run a rx pack on electric? Its not that the battery cannot put the juice out, its the internal BEC's/ESC's.

I for some reason thought this was a glitching issue on a nitro car. :lol:
