Hi Paul, put me in my place if I'm out of turn. I don't know if you've realised but olly 4950's boat is the 46inch model and will probably need a more powerful motor than yours, if I remember yours is the 36 inch. Regards Alan (used to be aslo44)
Hi Alan, mine is the 42" one also, but the veron design, so there are some fundamental differences, the biggest being where the shaft is, size of boat is the same
this is what happened to my different settings, I keep a record of all of them I suggest you do the same!
if we for the purpose of simplicity just concentrate on one prop, "x" 55mm two blade, available from any model boat shop, same batteries, always fully charged, and very similar weather conditions, all readings will be relevent to the fastest (maybe not most efficient) recorded gps speed (by the way, reason I asked, so many people just guess what speed the boat may be doing!
)
align 1620kv, 2.5:1 ratio 24.1mph, 64amps, 1389amps, VERY hot motor after 5 mins, it was watercooled,
Turnigy 880kv (as recommended) 1:1 ratio 25.55mph, 104amps, 2037 watts batteries where getting sucked dry with that massive amp draw in minutes!
1.14:1 ratio, 23.94mph, 82 amps, 1644 watts, motor was warm
The scorpion motor is more efficient as it can handle the demanding set up better, but pound for pound the turnigy was better value, the align however was an outrunner, with an outer can, and made a superb sound, like a jet turbine,
I suppose on 1:1 I could have used less volts! its a real interesting thing all this testing, and so suprising how just changing one gear by a couple of teeth makes such a difference, I have used 1.14:1, 1.25:1, 1.67:1. 1.43:1, 1.6:1 and 1.5:1 !!!!!!! with the scorpion, strange ratios, but its just using what gears I had, best setup is 1.5:1, 30 teeth on shaft, 20 teeth on motor, "x"55 with scorpion, pity you are not in north west, I could show you!
hope that hasn't confused you too much!
Paul
