the winches are 40 rpm at 6v, so around 30rpm at 3.7v (ish!)

I've used a few of those micro gearmotors in the past.  

Never thought about putting a spool on the shaft.  

Great idea.  

Where did you find the spools?

Hi Michael,

I machined them up on my Umimat 3. 

If I had been unable to do that, I would have used some tube, and soldered plates on each end.

In the UK we had 'Mechanical Horses' from 1934 to the late '60's, which were owned both by the railway companies and also by many industries.
This is a model (converted white metal kit) of the original 3 Ton version, which had an 1100cc petrol engine.
The model is radio controlled, 1:43, and will run for two exhibition days between charges (650mAh battery)

Hi Giles  :wave:



I gotta say as a BIG ! crane fan ...

... Your locomotive-crane is a great lookin' gal !!  :)



As for 'DHT 717' ...

... I dunno WHERE ??  :shocked: you are stashing all the R.C. gear in there Giles ??  :us:



But you seem to have the Paul Daniels '20 rabbits out of 1 top-hat' trick, MASTERED ...

... when it comes to making all the electronics ... DISAPPEAR !!  :P


Those ol' 3-wheeler workhorse trucks are somehow quintessentially 'British' to me ...  :old dude:

... I'm pretty sure I recall getting my Dads 'Dinky Toys' one from my Grandmother as a kid.  L:



Great stuff !

'British Racing Green' as well !!

FAST right ??  :slow: :slow: :slow: :slow: :slow:



;)



Si.

Hi Si,

Cheers!
Let me spoil the illusion by this photo.

The servo is a 1.7g type, and is situated where the engine would be (in the cab with a cowl over it).
You can just see the RX tucked in in front of it, and the wiring just gets shortened, pinned and glued as far away as possible.
The gearmotor is miniscule, but still powerful at 6mm x 8mm x 23mm, and is tucked under the chassis.

Hi Giles. 

What receiver board are using and did you have to program it for the servo?

Hi Rod,

it's just the standard Rx41d (road version) which comes with servo already programmed.
The only complication was with the servo mounted this way up (which it had to be!) it was operating backwards.

I know you can get servo-reverse boards, but I couldn't spare the space,
so I used a programmable transmitter - a Jumper T8SG - which allows me to reverse the servo signal at the transmitter end.
