just a quick tid bit of advice here, go with the scooter motors. there alot more robust if you get the belt tension all good i hear and they run for ages off a single drill nicad pack.
drills are fairly easy to use, but youll pay big time in busted ones in the long run if my experiences are anything to go by.
controllers wise, if your confident you can be responsible around $350 of electronics go for an IBC/Victors/Rs-80. be warned ive heard of people blowing them up as soon as theyve gotten them. but yes most definitely are they worth it, i used to use servo switching until i just got fed up with their fiddlyness and havent looked back.
armour, OUCH DAMN 0.5mm is woefully thin, i would say a slow wedge could rip gashes into it, 5mm aluminium and up for real survivabilty. dont forget fibreglass etc as an option either..
remote control? 75mhz american system no doubt about it in conjunction with a deans antenna. www.towerhobbies.com OR www.robotcombat.com and on the market place. 9ch PCM highly reccommended.

ive found online robot combat how tos largely useless in regards to designs etc. thats the beauty of the sport. no design is perfect or correct in everyway.

I'm basically thinking of creating a spinner as it should theoretically be an easier first bot thats still strong and effective.. and i didnt even see 1 at the last meet Very Happy
lol doubt that, take a peek at some photos of jolt, plan b etc and take a look at their running system. expensive, precision and chunky. if youve got yourself access to a lathe, welder or the money for CNC have a crack.
saws bolted right onto a car fan motor are a good start. not particularly effective but a good starting point.
batteries i would steer away from SLAs if you can, ganged up drill nicad packs are probably the option for the builder on a budget. SLAs like drills will leaving you paying more in the long run after you have to replace the dead ones.
IMHO the advantages of a rugged no sh*t brick bot are huge, particularly for the beginner such as yourself or someone who is still pretty bad with tools and accuracy like me lol. its always entertaining to watch people tear their robots apart getting it ready and just sitting back and watching with the reliable one
spinners.... well if you want the serious opinion MINI MAG, 3hp or so and 1.5kg, BIG TIME power but $300 US. get those from the robot marketplace. on the budget the magna TR thermo fan motors belt out very respectable power for a $10 motor. plan b gets the 1.5kg disk or so to 3000-4000rpm in 3 seconds hurt speed 5 seconds full now.
the best advice i can give though looking back on my experiences is A) listen to the experienced and B) get in there and try _________________ www.demon50s.com - Minimoto parts

The help is really good! Im surprised, most wierd hobbies when people ask for help they get flamed or "www.fuckinggoogleit.com" and similar. I'm really impressed. I suppose we all benefit with more competition to demolish!
Sorry for the typo, i did mean 5mm! not 0.5mm i meant 0.5CM!
I can even go stainless steel or titanium if i can source the materials.. or galvanised steel..i have a mate who is a very experienced welder, so he's good! I just have to design one and i will assist in construction of the chassis, but all the electronics and everything else are my domain.. The first design to make is soooo hard to pick, way too many to choose from.. there are a few i wont even look at because they just look pathetic! but some are a very hard choice in choosing..
I quite like annihilator's design with the roller (saw one make short work of a drum at last botwars) but ive also seen extremly impressive movies of spinners such as mobeious spinner, and the backlash off http://robotcombat.com/therobots.html
at this stage i think i am going to go with a design like annihilator, except obviously different.. but the same style of primary weapon.
As ive said in the previous posts tho, i still am unsure as to motors/gearing etc.. and the roller... not sure how the others are designed but mine will be belt/chain driven from a motor within the inside of the bot.. BUT what are the rollers made from?? I was going to get some thick steel tube thats hollow in the middle and like 1cm thick, then rig something up like that..
I do want SERIOUS speed and torque in the roller... Also as per the message about the scooter motors, where do i source them? I dont want to buy 2 electric scooters at $150+ each just for the motors..........
Again thanks for the help so far guys! feel free to MSN me if you wanna chat about bots of death!
