looks good!
just be aware the copper on the PCB will kill radio. At our ranges it might be good enough but if you have a problem thats where to start looking.

not really...

radio waves will pass through alot of materials... copper it wont, so if you covered the copper than in all likely hood the radio waves will pass through the covering and still hit the copper....your best bet would probably be to remake the top panel with some form of plastic... polycarb would be the best bet, you could pick up some 1mm sheet cheap enough and that will likely significantly help radio functions.... though put it all together and test it out Smile you might just get away without having to resort to that Smile

isn't the simplest way to find someone to etch the copper for you. Maybe leave in a funky deign.

I was gonna suggest the same as Mike. Etch the sucker Laughing Also thought about the crazy idea of turning the top panel into an aerial for the radio by etching a track the correct size for 0.125 (I'm avoiding Imperialism Evil or Very Mad ) wave length Laughing

as for the other small robots, gotta take a trip to jaycar tomoro to pick up some trimpots to get the servos going (note: dont glue the pots of micro servos), helix is all good cant wait till i get some money together and stick a brushless Twisted Evil in it.

looking good.
if you have the weight think about putting some kind of diagonal in to support the weapon uprights so they don't tip over if something comes in from the side.
