Model Boat Motors And Propellers

model boat motors and propellers

Motor - the power requirement is split between two motors on the model. i think two 500-size motors would get you there. master airscrew speed 550 or graupner speed 500 would probably work well. the work-point for the motors will probably not be at max efficiency, since it's a direct drive.. Perfect for small models using 1/2" to 1-1/2" diameter propellers. gearbox can be removed for direct drive use. 6 volt 400 series 3:1 reduction max rpm with gearbox: 5460 total length (including gearbox and drive shaft): 3-1/4" shaft length: 7/8" height (from base of motor mount to top of motor can): 1-1/4".
