I am running the Prather 45mm bronze prop. I got a 40mm plastic, maybe i should test it today. It looks really small compare to the boat 8) I am wondering if my Seaking 90A can handle this motor, the motor is rated 91A max. What is the chance i hit max amp draw?

Darter is about 20% slower with 40mm prop but it took twice as long for the batteries to get hot. i guess the best prop is anything => 45mm. Look like bateries issue has to be fixed.

Any update on this? I have a darter king i'll be putting hobby equipment in, how far (voltage) can the 3 standard motors be pushed?

Thanks

Hope to see more developments and other's work on their Darter..
