    I have a Mtroniks esc and it calls for a .1 uf capacitor attached to both the positive and negative terminals. I have never done this before but the esc that I have used in the past are very basic and probably didn't care if I powered it with a battery or a hamster on a wheel. My questions are as follows: 1) are the capacitors completely necessary? 2) does the voltage make a difference? 3) What is the reason for them? 4) does it matter what style of capacitor since I see many different configurations? Thanks for the help in advance.

    I know that when specific frequencies we used, RFI was a problem. Know that we have gone to 2.4 radio, is it really still a problem?

    It's not just the antenna picking up noise, it's every wire to/from the receiver, too. Any long wire can act like an antenna and inject noise into the system if not completely shielded.

    Thanks, hadn't thought about the wires picking up RFI.
