Well, ok, I've gone for two of these: http://www.electronize.co.uk/model_elec ... frames.htm (FR15HVR). If anyone strongly objects, please do so ASAP, I'll probably be ordering them tonight.

I am going for the Planet 5 2.4Ghz transmitter and reciever shown above.

I've gone for the slightly more expensive ESC's because the drills I was going to get don't get delivered to Spain, and they don't even exist over here. I'll be going tomorrow after school to check out some cheap drills locally. It's just on all the websites I've visited, they've been pretty expensive.

Oh and I know it's possible these two ESC's won't be able to run 4 drills, I might end up having to settle for a 2 motor bot :c...

Which is still ok, since I'm not going to be entering anything for now, lol.
Thanks for the helpful comments guys, much appreciate 'em.
