My first TTTT

I finally finished my first 1/87 scale tractor trailer. I posted a video on youtube

http://www.youtube.com/watch?v=CNTAX...e_gdata_player

It's radio control using Spectrum 2.4 GHz transmitter and reciever. It also uses a Spectrum servo for the steering. The motor is a GM15 pager motor with a 25:1 gearbox. It runs on a 200 ma Lipo battery. It uses a modified servo board for the speed control. I need to build a better speed control (esc) because slow speed doesn't work as well as I would like.

I also want to add lights to it.

As you can see in the video, everything is housed in the tractor. One of my biggest challenges was finding small bevel gears. The ones i use now are from a
Rc helicopter tail rotor but I would still like to find smaller gears.

I made alot of the parts on my small Sherline CNC milling machine and my Atlas
Lathe (you could make the parts without a CNC machine but it would take a little
Longer.

I would be glad to post pictures of the internal workings if anyone is interested.

John
