Cool

The OP was a drive-by, hasn’t been back since he posted over two months ago. I’ve built quite a few R/C airboats, all were either larger or smaller than the Windy. We need some information before we can give informed advice:

- What speed and run time are you looking for?
- How much money are you planning to spend?
- How much experience in FE boat building do you have?
- Is the boat completed, or do you still have some flexibility in component placement?

Without any specifics, my suggestion would be:

28mm outrunner, length at least 20mm, Kv around 1100
4S battery, minimum 30C and at least 3000 mAh
ESC with a minimum of 50 amp capacity
Prop will depend on the motor size and Kv but start with an 8x4 fiberglass prop
