hi, iv got a pair of these motors in my pusher tug, they are 12v and 80mm long.....im running 2x esc's and if i go full power the motors are blowing 15amp blade fuses....................can you tell me what the motors are please...........

[Martin (Admin)]

That looks like a Robbe gearbox on there.... maybe Graupner or Multiplex.

hi ya
 
Could it be a Graupner Speed 600 with the 3 to 1 gearbox on it?
 
I have one here 600FG3 and its total length plus gearbox is 80 mm.   It's operating voltage is 7.2 - 12 volts.   Its idle current drain is 2 amps.  Max efficiency is 12 amps but its storl current is 85 amp.
 
So its a possibility.
 
aye

these motors seem quite greedy on powerits blowing 15 amp fuse if you face the bank and power it up..what are they like as motors?

grace.......this image suggests that the gearbox is not mounted squarely to the motor....and a certain misalignment is evident with the flexible coupling

Both of these have the potential to draw additional or excessive current...............Derek

The size and pitch of the props would have an impact on the amps drawn too.
How big are they?

[Stavros]

I think the props are around 40mm 4 bladed ones in Kort Nozzles

hi, derrek your correct when i took the pic the motor had rotated in the mount..i turned it to the correct position and used a cable tie to hold it firmly,,,

stavros is also right ..40mm 4 blade bats in a kort knozzle
