My efoil
Firstly I would like to thank everyone for the great wealth of information found on this site, it gave me a good understanding of what route I would like to take my build.
Nothing ground breaking here but I wanted to document my build to add to all the information on Foil Zone.

Fail safe. Reciever has built in failsafe so loss of signal from transmitter sends throttle to zero, also I have a reed switch and magnetic lanyard on the signal wire between the Reciever and ESC which means the ESC detects loss of signal and sends throttle to zero.
