My nephew wants to build an antweight robot. He is building it on a very tight budget so we are looking to use servos for the drive and for a flipper. We have looked at the servos on Technobots and at the much cheaper ones on Giantcod but would like some advice on which ones would work. If anyone wants to throw in a suggestion it would be most welcome. Thanks in advance. :D
http://www.robotwars101.org/ants/shop will happily sell you pre-modified servos and other bits with which to build ants, I use the Naro HPs which aren't bad at all (although they are in a fleaweight)
Ian,
I assume even though he's on a budget he still wants it to be competetive?
You can run the parkflyer hpx f on 7.4v without much problem and they are pretty fast. They aren't the cheapest ones but they are reasonably easy to modify with a bit of superglue and a 6mm drill bit.

They're a bit bigger than micro servos but you can still get comfortably in weight. with something which will flip rather than lift another antweight.

Hi Ian.
How tight is a tight budget? One option is to get a couple of the little gear motors and run them off the servo boards in standard servos (£5 each on sussex-model-centre if I'm not mistaken), though the motors are still a bit more pricey, you get a much better performance from them.
If you're going down the servo route, my faves were always SD200's. Hard to speed mod, and the gears tend to strip fairly easy, but they did me well in so many robots, and my best ants all used them. Also recommend the park flyers, heavier, but easy to speed mod and great for a weapon servo.
I've got a micro reciever you can have if you want it. Its on 40mhz and it's no real use to me, would be good to give it to someone who's gunna use it.
Thanks for the advice chaps. I think we'll go with Andy's suggetion and put a hpx for the flipper with something smaller for the drive. Dave the micro reciever would be very helpful, thankyou, I'll pick it up at Whitick if that's okay. Once again thanks for the help.
I shall do my best to remember it for Whittick for you. Got a few other bits and pieces lying around you could probably use too.
