I have a 6' home built yacht I took out of moth balls (2 ys) and now have a noise issue at the motors. The boat has two Astroflight Cobalt 40 brushed motors with caps. Currently setting it up with a 6 channel 2.4G Tx & Rx. Previously ran with a Kraft system. Should the Caps be replaced?
Also have about 2' distance between ESC's and motors. As I recall this wasn't a problem before. Any suggestions?
