I'd say a 280g servo is perfectly usuable

I bought one of these recently, most likely to be used for the lifting mechanism in my Cassius replica. Not the fastest (although with the correct leverage/linkage it could be) but it's meaty as hell in the torque department. Weighs 160g and costs £12, can't go too wrong with it.

can't go too wrong with it.

unless you let out the magic smoke genie by running it on 7.2v

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

i using two of those together for more torque
my parts list(basicly the same as david westons)
2x 100:1 mfa como motors
12v 2600mah nimh
10mm thick hdpe(chopping board!)
40mhz radio gear.
got an old electic screwdriver motor which may end up being a spinner

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Would any brushless motor so it?

And how re you connecting wheels to motors and how would you connect the spinner motor to the spinner?

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

a good sized brushless out runner would be fine for a weapon
my wheels are held on with araldite, probably not a good idea to mount the disc directly to the motor

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

I thing I may go with a drum spinner when I get round to it since it's not as hard to build as a disk

My Beetle is probably going to cost about the same as Bitza, but that's mostly due to weight issues. Most scrap parts are heavy!

My component weigh in leaves me with 600g. That's to include leads, connectors, mounts, pulleys and some sort of chassis to hold it all together....

Also my fisrt time using Li-Po and brushless.

Don't worry though, still upholds the Bitza motto! Bits of lawnmower are obviously included.

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

I use:
2x MFA motor (15:1) with 50mm wheels for drive
a 12ah sabretooth speed cotroler
lego pnumatics, with a deodrant can, or copper pipes for the cilinder
and 6mm hdpe for the body
and 1.5mm stainless steel for the armour
and I dont have a battery yet

but is there going to be an event? because if its going to the guildford event its getting quiet close

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

alex you dont really want to use lego pneumatics, there best in ants.
Try the ripmax air retracts we looked at...

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Well the lego is only tempory untill I can afford better, and anyway from my calculations I can have 20lbs of force at the end of the flipping arm!

Just found this;

http://www.robotmarketplace.com/products/0-B62.html

Apparently very popular in Beetles in America and come in several gearbox ratio's. Good amount of torque, especially compared to the MFA's on Technobots and lighter.

Unfortunately gotta order form America, haven't looked to availability in England yet.

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

They are good, Ive got some for my beetle if I make it...tried them out on a test chassis and they were pretty good with a 20mm wheel. Kenny also has them now in the latest version of 180

[PJ-27]

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

Where did you get them? From RobotMarketPlace?

I can find the gearboxes in this country, but not sure what the motors are?

[Mouldy]

Re: UK Kilobots - 1.362kg (3 lbs) Combat Robots

me and kenny just got them direct from Robotmarketplace...there P+P cost's arent as bad as everyone thinks... and there delivery time is quite good too.
