16.8km/h is really above average for a featherweight - certainly if youve got a spinning disc as you should be focusing weight into this.

Whats your budget for the weapon?

But can i really let my robot run 16.8 km whit your motors?
And should i juse 1 motor for 2 weels or for each wheel 1 motor?

Motors for Disc you could try the HTI motors from http://www.robotmarketplace.com www.robotmarketplace.com motors section misillanious motors they are cheap but powerful 1.44hp at 24v. On our feather Kishar we use 2 to power the Disc. Go to http://www.teamdragon.org.ukwww.teamdragon.org.uk kishar page there are some pics and videos of the set up. For drive we use 18v drill motors at 24v plenty fast enough.

http://www.hopf-modelltechnik.de/http://www.hopf-modelltechnik.de/ if you can read german. Very good pricing for their batteries.

We use the graupner speed 900 with good effect. Bit large and heavy with 660 gram each, but very powerfull and efficient for a low RPM (6000 rpm @12V) and good pricetag Â£20-25 if bought over here.
But the Graupner speed 720 BB torque could also be a good option.

For batteries, if you go pusher, I would take the Hopf Sanyo 3700 sub C NiMH in the 12V 2*5 stick pack cells. Â£20+P&P per pack.
