It is a shame that the maker chose to use a cheap AM radio with the SV, but it is easy to understand why - lower entry cost. AM radios regardless of brand are poor choices for BL-powered boats....they are more prone to interference and have limited clean range. Upgrading to at least an FM radio should be mandatory, and DSM is probably better. I had glitching problems with my FM radio and switched to a Spektrum - zero problems.

There are several things you can do to reduce AM glitching in a boat like the SV. Do not rely on the BEC, use a separate receiver pack in the boat. Make sure the transmitter pack is fully charged/changed often - do not rely on the meter on the transmitter to tell you if the pack is okay. Move the receiver and antenna as far as possible from the motor, packs and power wires. Keep any radio wiring - servo and ESC leads especially - as far away from the motor/packs/power wires as practical.
