Where were you at with your props Rake? Maybe that was the culprit...
As far as the 2,3 and 4S debate goes- its all about that prop RPM and C rating as far as Im concerned. If I could get my Bolt NOT to take on water I think it would be a missile and worth trying a slightly larger prop. The whole taking on water thing concerns me the most. I got some cash tied up into the boat and I would cry if I lost her.
Hi Bass, 30mm prop. She was only on the water for 2-3 mins before this happened. Not alot of time to take on much water but highly possible she did.
Dude - I'm crying bucket here. 2 wrecked hulls and i dare not tell my wife how much cash I have spent.
Anyway, I have some news....
Astec were kind enough to test my ESC and the BEC is putting out 4.8v no problem and no heating up. ESC is fine and not the problem.
I also now know that this ESC is bombproof and also highly waterproof - 60A turnigy ESC order cancelld.
I think I have found part of the problem I just tried the stock bolt esc that came with it along side a keda 4800kv with no servo plugged in and all was well.
The Rx bound to the Tx, the Rx LED was solid red and the motor bleeped and responded perfectly to the throttle.
I then plugged the savox SH-0256 servo I bought the other day in and No Rx LED, no response from the servo or throttle and no beeps from the motor / esc.
I then found that both the ESC and servo were heating up beyoned the norm.
I hooked up another servo that has never been used and everything worked fine again.
This proves the Tx / Rx, ESC and motor.
So it looks like something is causing the servo's to very regularly and this is affecting the Rx.
3 quality servo's all failed leading to crashes and all manner of unwanted results. Â£65 on servo's alone.
This must be what caused the crash, but what could be causing the servo's to fail in this way ? water ? but the servo's are waterproof.
