possible interference?. - 04.10.2010, 07:45 PM

possible interference?.
Wonder if any of you I pass something like:
Restarts repeatedly the values shown by the telemetry.
The speed signal returns to zero again and again especially when operating the steering servo.
And also at random to be stopped the car and drive the servo direction occurs as interference and moves for a moment the car backwards.
The receiver voltage values appear normal.
Try a 2200 micro Farad capacitor and 16 v and a ferrite ring and did not fix the problem.
I have installed:
mmm combo kv 2200
Spektrum Telemetry Receiver
cc fan
5 s batteries 5000 ma and 30c (blue lipos)
htx bullets 4mm connectors
servo direction SAVOX 20 kg
temperature sensor used in the motor nitro
rpm sensor
Any help.
Best Regards.

Maybe drawing to much on the bec and dropping voltage? Thats my only guess

Seen a few guys report similar issues with speky radios lately. I keep suggesting a glitch-buster capacitor as a solution; usually works unless its a more serious underlying issue.

the feed is probably from the mmm internal bec.
remove the red wire from the mmm and place an external battery to the receiver and fix the problem.
then you should buy an external bec.
which of the cc bec buy:
cc bec?. It is less expensive.
application will comply with safely?
cc bec pro? I think oversized?
Thanks for your answers!

The normal cc bec should be more than fine, unless your steering servo is a monster.

Even then its fine - I tried stalling out 2 7955TG's off of a CC BEC and CC BEC Pro... The servos would pull about 5 amps but both BEC's seemed to do the job equally well...

I am using a translator ...
Then I will ask for a cc bec to solve the problem.
If I use the jr servo Losi 8t rtr not have these difficulties.
But I want to use the servo SAVOX. It seems more reliable, although it is more noisy.
Thanks for the help!
