Hi Guys, I have a strange issue with my boat. I bought it used, and modified. I've been putting it back to stock...
So my latest change was to put the stock, plastic prop back on. The one that it had on it was smaller, about 1/4 inch around smaller. It ran fine with that prop, but seemed to cavitate a ton. If it wasn't a smooth launch, it would just grind without going too fast. I had to let off the throttle, let it settle back in the water then go it, and it was fine. So I thought I'd try the stock, larger prop, thinking that the larger prop would dig into the water better.
:help:
However, right away what I found is that at full throttle it cuts off. Whether I grab full throttle at once, or ease into it, it cuts off. Once I let back to about 2/3 throttle it kicks back on again. With the other prop I got the same thing once I’ve been running for 10 minutes, and I’m thinking that maybe the ESC is set for LIPO… I don’t have a programmer. Could it be that with the larger prop, it’s drawing too much from my NIMHs to kick on the LIPO cut-off even with a full charge? Or is maybe something else going on?
