OK Neil,

Let's give this a shot.  I am distinctly CADless so bear with me.  Let's 
take a bit of a journey, shall we?.......

First, I watched these videos:
http://www.youtube.com/profile_videos?user=Gizmo4t

I paid particular attention to the part about the transmission.  Please note 
that the gas engine is speed controlled and does not reverse.  Also note the 
way that the forward/reverse action is brought about by means of two shafts 
spinning in opposite directions.

Second, I found this gizmo on C&H's site:

DUAL MAGNETIC CLUTCH ASSEMBLY OGURA #MCCU-15A. Contains two independent 
magnetic clutches mounted in a common frame. The individual clutches could 
be removed and used separately. Both clutches have chain sprockets attached 
to the input and output shafts. One clutch has 16- and 24-tooth sprockets. 
The other has 11-and 22-tooth sprockets. Pitch of all sprockets is 1/4". 
Clutch operating voltage is 24VDC -at- 250 mA continuous duty. Wire leads. 
Dimensions: 4" wide x 3" high x 2-1/2"thick. Stock #CL9101 $6.95

Are your wheels turning yet?

Third, I found this:

24 Volt 300 Watt Kollmorgan® Brushless Motor With Built In Speed Controller
Built-in variable speed controller works with any 5k Ohm throttle or 
potentiometer to vary the speed of motor from full stop to full forward. 
Counter clockwise shaft rotation facing shaft. 8mm OD D-shaped output shaft. 
3-bolt mounting pattern. These are the same type of electric motors that 
Currie, Lashout, and Synergy electric bicycles plus Currie USPD Pro-Drive 
electric bicycle kits use however they are not compatible with those bikes 
because they rotate counter clockwise instead of clockwise. Recommended for 
electronic hobbyists, electric scooter and bicycle builders, and electric 
vehicle experimenters. Our super low pricing on these motors is due to a 
surplus overstock purchase. Weight 5.9lbs.
item # MOT-K24300

I found these things over the course of about six weeks.  I am also trying 
to get Joe Sommer of Anvilus to map an additional proportional output on the 
C6C to drive a 5K ohm potentiometer.  I hope this pans out, as this is kind 
of key to the whole shooting match.

So, the equipment list would be:

1 300W scooter motor W/ speed control
1 5k ohm potentiometer.
1 smallish servo
2 pairs of 24V electric clutches
1 Anvilus C6C or any other radio control
1 Anvilus mini relay controller W/ relays.
and plenty of 24P chain, sprockets, shafts, bearings, etc.

The speed controlled motor would drive two shafts, like in the video.  These 
shafts would then be connected to the four clutches, one clutch for each 
direction for each side of the vehicle.  The clutches could then be 
controlled by the Anvilus mini relay controller and a set of relays.  The 
outputs for the clutches would then be connected to a pair of output shafts 
or directly to the final drives.

I suppose that one could vary the components quite a bit and still get the 
thing to work.

Does this help?

Paul Hilton.
