Heng Long gearbox specification
« on: June 15, 2018, 12:29:25 PM »
I'm trying to work out which unit to get to drive a 1:26 The Alexander Arbuthnot side paddler.

None of the ads seem to provide  default RPM out data.

Can anyone suggest which model of the Heng Long range should I go for?

I assume that a pair of speed controllers would be able to adjust the actual paddle revolutions.

What  range should the paddles nominally rotate at ?

I realise these are  newbie type questions so please allow for my ignorance.  ;D

I measure the output of the ones I've got at around 150 rpm but that was without a controlled supply (just hooked up to a battery)   I think the required RPM really depends on the diameter of the wheel.

Thanks for that, more  or less what I had gleaned from other posts.

I bit the bullet and bought laser cut paddles for the boat I'm emulating, The P.S. Alexander Arbuthnot, a working  Murray river (Australia) side paddleboat.

They are 120 mm diameter.  7 paddles
