i have put a 370s 4400kv brush-less motor and a water cooled 20 amp esc with a 3s lipo in a mini c hull along with a spectrum receiver and new servo. The running gear is all the same except for the prop shaft witch is now threaded to take different props. I have tried three different props all about the same as the stock mini rio prop with different pitches i have even filed one down to half the original diameter and tried it all with the same result. the boat just flips no mater what. even when i try to be gentle with the throttle it just flips before it even gets on plane. with the moded prop i could just get it on plane but it still wanted to lean hard right and the cavitation was horrible. Anny prop or drive advice would be greatly appreciated.
Thanks
