hi does any one know if electronize 543-23 motors 3 off would run 45mm props (P) type on 12volts ok in a 1/128 hull using FR15HVR speed controllers one for each motor these motors rev@8300 and shouldnt need a gearbox does this sound ok????  i was going to use eco500 motors but thought this might be better.

sorry to be a pain i was going to get eco500 motors but when i tried to order cmb were out of stock so i ordered the electronize motors but now they are here the sticker on them says max prop 30mm but i wanted to use 45mm does anyone know whether they will be ok please? :-\

45mm on 12v may be pushing your luck a little. you could try it but make sure you put an appropriate fuse between the battery and esc.

What props are you fitting?
You MIGHT get away with it if they are quite fine pitched but you would need to do a bath test
with an amp meter.

thanks for answering am i using too small a motor or too big prop size(fine pitch) its a fleetscale hull 77"long i havent a clue?on the drawing they measure 45mm props i thought smaller props wouldnt be enough for a boat this size please help, what if i wire two motors in series would this be better it makes them run at 6v if i understand correctly.
