if youve got a budget of $600 and you want a serious drum, then i would suggest you could build most of the robot for less than $200, using one of bretts picaxe controllers and spend some good ole money on a big drum motor and decent set of nicads.
btw dont forget, a huge full body spinner may be the best design going, but without access to special tools the chances of getting one going are likely to be slim, build to ones ability.

with scooter setups just buy two 34 dollar premade drive trains with mountts and eveyrthing, all u need to do is drill soen holes and mount the thing and u get eveyrthing needed and its all premade and good
To drive the drum reboot is doing alright with friction drive by looks of it.
Drum weight go for around 3 kg though i would suggest _________________ Andrew Welch, Team Unconventional Robotics

What about a receiver? Does the $300 control board do this? Or is it an additional thing?
Ive ordered the motors, ordering control board, ordering the remote contol unit, now what about a receiver for the bot?

the reciever comes with radio gear, the reciever is what picks up the signals from transmitter (hand held controller) and that controll commands to IBC or servo's. They come wioth any bought radio set from what ive seen. _________________ Andrew Welch, Team Unconventional Robotics

how much is a transceiver/receiver combo? Where should i buy from?
How many channels? i plan on having 2 wheels, and at this stage 1 primary
weapon.. so that would indicate to me i'd need 4 channel (so i'd have one spare?) would that be a correct assumption?

I would recommend the futaba skysport 4ch. I got mine from hobbyco in sydney for $200 with reciever and 3 servo's, which is a bargain for a 4ch. It works really well, and alot of other people use it too.
However, there's also the pistol radios, what ever you feel most comfortable with. _________________ ( •_•)

i don't know about the 4 ch there will be times where you might be wanting that extra channel for a weapon and have to shell out another 300 + for more radio gear.
Be sides you never know what else you might be getting in to latter on in life IE you might want to going on into rc planes or helicopters. i know i am for reasons fun and evil _________________ For West ausies interested in robotics email me at: theoneshrug@hotmail.com

Is it worth using a Gyro at all? And im thinking of buying the relay control board as a starting point.. But the only downside is relays are ON or OFF so speed control in movement would be an issue.. would require jabs on the control to move slowly rather than the speed incrementing with the slight movement of the controller.. Is this correct?
ANd if it is, are there any ways around this? only for movement.. speed controller perhaps?
Are failsafes built into the controller/receiver? or is it an additional thing?

You know, one thing i've been kicking me for is that for $200 off ebay.com.au, you can get rc heli kits with a 6ch reciever and transmitter, and all the parts are seperated, you could play with it for a while, then reuse the rc gear in your robot (i would have done it if i knew!)
http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=2563&item=5972758321&rd=1
Check with the seller if it's absolutly all seperate rc parts, and i've found that revolution shop's the best. _________________ ( •_•)

A gyro would be no good with on/off control. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems
