This is my smallest fully remote controlled trial truck!
I used an old 9V battery box along with the PF extension cable, PF receiver, M motor for driving and a micro motor for steering.
The offrader has a tiltable rear axles, which utilises a 12 and 20 tooth gearbox, which can engage at an angle, therebye eliminating the driveshaft effect on suspension.
The gearing is only at 1:2,778, which means this model is strong and fast. Also the model has a total of only 8 gears in the driveline.

Another very good truck!
How did you connect the IR receiver to the old 9V battery box? I thought you need a PF Battery box for supplying the receiver, because as far as I know the extension cable uses 2 ports (when 9V system-PF are connected), while receiver uses the other 2 ports.

I used a trick shown at technicbricks. You use 2 small alu foil pieces where you connect receiver to extension cable. You have to watch the polarity, so you dont fry the receiver.

Alright...i’m VERY confuzed here:
1.) HOW EXACTLY DO U CONNECT THE MICROMOTOR TO THE PF RECEIVER?
2.) WHAT TYPE ( PLZ ADD BRICKLINK ADDRESS ) DID YOU GET THE BATTTERY BOX?
3.) HOW EXACTLY DID YOU CONNECT IT?
Since i’m new to this and i only have used Power functions, and i kinda want to branch out into RC and MICRO moters, i would like some info regarding how to connnect-cross-motor-sysytems. Thanks!
