ha ha I was dreading you turning up Ghosty!"!
To answer Phil also (thanks for kind comments) the gears used (MFA) are not very expensive, so initially we had 2.5:1, which gave very fast acceleration, but the esc sometimes went into "safe mode" not allowing full throttle for the first few seconds. The setting can be changed, but on the "very fast" setting, castle creations waive the warranty
The fast acceleration is great for the 2 small local lakes I test on. run time was embarrassing, wait for it........10 mins flat out
, but boy are you sweaty and shaky after 10 mins on a small lake!
I have tried 3:1, thinking for the bigger lakes slower acceleration, faster top speed, its easy to change the gears as the prop one stays the same, its the motor one that comes off, but the belt needs changing also as the length now differs. Didn't really see much improvement in speed, although I didn't have any reliable test equipment then. The optimum seems to be 2:1, but I am convinced the motor has more to give, still fast acceleration, but I think it will go faster top speed if I can feed the throttle in slowerand maybe back on 3:1.
For now, its the props, we did briefly try a massive 60mm brass prop, similar to a cleaver, I think it was a "steamer" but it scared the life out of me at Gautby (big lake) as it nearly turned over with torque roll, I lost a vent thats how far over it went (hooligan!)
Run time at present a whopping 15 mins
unless I throttle back, but my left thumb will not do that, flat out or stop is all it knows!
Ghost, 20 Min's!!!!, I would be fun though, I was by Gautby a few times over the last few weeks, the thing that worries me is where did the shopping trolleys go when it was frozen over, I bet they are not that far under the water level, that would be a painful experience if we hit them,
