Just figured i would say hi...LOL joined up for more info on a boat i just got, an old Graupner Monster vee. Boat came with a resistor speedo powering 2 graupner speed 600 motors, thru a 2:1 gearbox, out the back thru a strudder with a carbon Graupner 47.5mm prop with 1.2 pitch.... so far i swapped out the speed 600s for a 2150kv bruahless system, and plan on running on 3s...

i had rewired the speedo to power just 1 of the motors since it was slow as snot with them powered in series (and i knew it wouldnt have an icecubes chance in hell of running both motors parralel on 3s) and the few min it ran, porpoised like mad... but ran nice and fast...LOL for a wiper speedo brushed sealed can motor....

Anyone with tips on the porpoising?
