Welcome to Mayhem. What power source is a good question. Before using I/c. It would be a good idea to
make sure youve somewhere to run it. Many places do not welcome these. Noise Speed oil pollution etc.
Electric in a big model begins to get expensive. Brushless motor Speed controller Lipos charger etc. But more
places to run. Please remember to get insurance. Usually through a local club. Just in case. Just a few thoughts
Happy sailing . John.
