Hawaii Kai gets a maiden in the light. Final run of hobby king 30amp esc.

Got the ‪@Dr_Jet‬ short circuit, Hawaii Kai themed rc hydroplane out durning the day. went well until, what I believe is a overload cut. brought home and did a bench test and the ESC let out the magic smoke. The autopsy reviled a chip on the red wire motor side had a burned dot in the middle of it. I should have known better. It should have had a 50 amp in it to begin with.

Thanks

What motor/prop? If you are using that 4000Kv green outrunner on 2S, start with an X427. That will allow the motor to spin up where it's more efficient and not eating as much current.

[@brandoncocola1322]

No it's a 450 motor 3500kv on 3s with a 32mm plastic prop.

[@Dr_Jet]

Those plastic props are pretty inefficient. The CNC aluminum props can be had in appropriate sizes at fair price, check OSE. (I'd start with X430 or X630 with your setup). I like letting the motors spin up a bit, things seem to hold up a little longer with a lighter load on things.

@@Dr_Jet I got plastic props because it gets me in the ball park for a metal prop. Plus with one of my other boats when I did a maiden it got stuck wide open throttle and ran into the shore. It broke the plastic prop off the shaft otherwise it would have made another run across the water with the front split open. I do have a 430 prop I can try, the atlas likes the 32.

[@Dr_Jet]

Yeah, I do run my Atlas with an X632 and it really likes it, but for the shovelnose, I slow it down a lot with the smaller prop and get stupid long run times,@@brandoncocola1322
