Freebie drawing of a P-Limited 4-cell LiPo Brushless in-runner Outrigger Electric Hydroplane.
Note, this KEP's FE-4SL is a P-Limited 4 cell outrigger that is mostly run in the US with a spec motor (Aquacraft 36-56-2030KV). The boat can be fitted with motors with physical dimensions of 36 mm diameter and 56-65 mm long.
If you plan to use a bigger motor then that there is now an P-Open class rigger also called KEP's FE-4S. That suits motors of either 36 or 40 mm diameter and up to 74 mm long. Click HERE for info of that.
