Hello!
I decided to share my mocs here with this professional team. I build technic vehicles, LPEs, etc. since long ago. I'm member of Malug(hungarian Lego users group), Hunlttc(non official hungarian Lego truck trial team). I build mostly trial trucks(lot of them waiting for upload), contsruction vehicles, models.

Nowadays I realize some of my ideas:
1. Flying machine:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=500935
A simple flying object which isn't a single propeller, so can be a machine. Max. height is about 0,4-0,5 m, but it rises from it's own power(pullback motors).
2. Radio controlled gearbox with RC unit:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=502229
Uses simply the servo output of the RC unit, so you don't need another motor for shifting and both 9V output is free.
Recommended for bigger and heavier vehicles because it needs some space. Ideal for vehicles with RC system. The truck is a study of suspension, the rear one is my own development for heavy trucks:
The axle is suspended in four point, strong rubber bands are the "springs". With rollers in the wheels they can carrie much load.
In the front axle only the gray 10x1 technik plates(instead of 9L links) are new: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5465283
The axle contains the old differential with lock too.
3. Another gearbox, but for small vehicles and relatively low torque:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=504221
In this case:
http://www.brickshelf.com/gallery/mbmc137/Ideas-Technologies/4speedRCgearbox/004.jpg
- it would be a simple(but not usable) motorized gearbox.
With 3 more pieces it doesn't allow to be two speed engaged at the same time:
http://www.brickshelf.com/gallery/mbmc137/Ideas-Technologies/4speedRCgearbox/005.jpg
The motors help each other. In the sifting from 1. to 2. speed wit the (1.) motor, the another motor(2.) is in central position, nothing extraordinary happenes. But in the shifting from 2. to 3. speed, the steering piece pulls off the driving ring from second speed and the (2.) motor engages the 3. gear. The gearbox needs friction in the axle of the red shifting piece to prevent the "re-central positioning" of the motor, which turns only a 1/4: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=5480676
Shifting from 1. to 3. and 2. to 4. speed don't work, but you can shift from 1 to 4 or backwards.
The most important: in this gearbox each position of the contollers levers corresponds to one gear:
Right lever down: 1.
Right lever up: 2.
Left lever down: 3.
Left lever up: 4.
