I have one of those Head of the River 32” mono's, which I’ve been running for fun over the last couple of months, on 4s1p (2xpolyRC 25c 5100), an 8xl and a Hydra 120. It’s a great handling boat compared to my old Supervee, much more stable and doesn’t have that tendency to want to fly all the time.
Anyway, on an X642, I get a speed of 44mph on GPS, with spikes on the logger of 118amps. Everything runs fairly cool but even running loose it gets kind of boring at this speed.
On an M445 things get much more exciting, and speeds are up into the early 50’s, although during the brief test that I did with this prop, the logger was showing spikes at 158amps – whoops..(I’m totally amazed I didn’t fry the esc!!!) , everything got extremely hot in about 2 mins of running and a solder joint melted on the logger!!
I really want to get some more speed out of this thing without risking frying the electronics, and I was thinking perhaps an 8xl is a little too hot? Could I be better off with a 9xl which may allow a larger prop? Also a larger esc – I was thinking about an ETTI 150 race (apparently these will handle a burst of 300amps?). The hull is quite a weighty layup compared to my old SV.
If money was no object, would a 6s1p setup be better for this hull? What would be the best motor/esc setup to get this boat in the late 50’s early 60mph’s?
Any advice greatly received!
