I also have the same issue. Well, my neighbor does, anyway. It's a new unit. Took it out for the maiden voyage and noticed a pretty loud whistling sound. Also, 3 of the motors were hot to the touch. All of my other solo's never had this issue. Any input would be appreciated. Thanks.

Thanks for that. Can anyone else explain why these faults have happened to not just myself but seems maybe more out there. Cheers
