I have a Great Planes Wave Rocket about 12 years ago and the ESC has gone out in it. I was possibly looking at upgrading some things as it still has the AM radio system in it and still running the brushed motor. Most parts are discontinued as well as the boat itself. I did find a replacement ESC for it, but I was wondering if anyone knows what size or kind of motor they come with. There are no markings on the motor itself? Or anybody know where i can go to find out more about this boat and its components. I've tried everywhere.
Please help.​

Can you post pics and rough dimensions of it? It's probably a 540 or less likely a 550. Probably around a 20-30 turn.
