Motor capacitor question?

Hey guys and gals got a question about a recent problem we had during a battle. So my sons Duca still getting things straight. Sea trials went well and even her first battle was okay. So second battle problem rudder servo going crazy glitching NUTS every time the pump was on. So after trouble shooting it dawned on me. The pump motor was interfering with the signal. So I dug around and found a old drive motor that had a capacitor did a quick rap around between the motor connection and bam problem solved wooo hooo! So now I’m wanting to install capacitors on my drive motors and pumps to prevent future problems. So the capacitor I installed has no numbers so no help there dang. I read many articles but everyone has there own idea on what works. So I’m hopping someone with experience in this matter can get me straight on capacitors

I may have just answered my own question found this on the net . Straight and to the point. https://www.pololu.com/docs/0J15/9

 

I've always followed this guide

Even before I found it, this is pretty much what I did for capacitors, as taught to me by my father who raced cars back in the day, and won some trophies.

Sadly it looks like the pictures are no longer on that website though, so not sure if it can help that much.

3 caps, one between poles, and 1 from each pole to the can.

 

No sir no switches. Running B-board, 3s lipo, Turnigy 2.4. With a hobby wing 1060 esc. My Doria is running basically the same set up except my Esc is an 880 Hobbywing and I have no issues

 

Looks like you solved your particular problem but I’ve also heard of servo twitching due to:
-servo lead too close to motors/solenoids
-corrosion on servo connector (especially when using extensions)
-bad servo
-bad Rx
-un-capped motors with with the lower frequency radios
-dual sources of power to Rx (drive ESC and pump ESC without one having the bec removed)

 

All good points
