Re: How to make an antweight
So is it possible to use just the receiver with its battery to power 2 x modified servo's for drive? There is probably a diagram of this above that I've missed...
Edit: yes you can lol sorry. Do you know if anywhere sells wheels to screw straight onto the servo outputs without needing to modify them?
Re: How to make an antweight
Not that I'm aware of. What servos do you have?
Re: How to make an antweight
Yep ants are quite simple.
You will need to mod them to make the servo shaft go 360 degrees
Speed modding is also useful.
You can find youtube videos etc of how to do it aswell.
Whenever I mod it fails so Im not saying anything more

You can, but it isn't the best option. Servo drives tend to be slow and weak. They also have short life spans. I think my servo drives lasted three events before coming apart.
Small gear motors and ESCs are a better option in my opinion. I have been using BotBitz gear motors for years now and my first pair are still in use.
Re: How to make an antweight
That's wicked. So then like its just a case of finding wheels to bung on the end. Am so starting one of these this week.
Re: How to make an antweight
these will fit onto a gearmotor with a d-shaped shaft.

if the botbitz have d shafts
Re: How to make an antweight
I use these wheels. I drill their centre hole out to 3 mm and grind them down to a 20 mm diameter. Sometimes they require a little CA glue to keep them on.
Re: How to make an antweight
Phil is right, servos aren't the best solution, but they are the cheapest. If you can afford the botbitz motors and controllers and the postage then definitely go for it. I know Marto is also manufacturing a kit which will be very reasonably priced.
But if you want cheap and cheerful, using servos you can probably make and antweight for less than £15.
Re: How to make an antweight
Yeah the fact that the servo's were a cheap option looked good lol. I'm half way through building a new featherweight but the ant weights seem to have a really busy calender with loads of stuff I could get to.
Re: How to make an antweight
Servos needn't be too slow - the TowerPro MG90s are easy to speed mod with some spacers, which increases the speed considerably to be on a par with some gearmotor driven robots.
They have nowhere near the power or torque or durability of the motors though - and as a pair of motors, mounts and wheels cost less than £40 I would reccommend them strongly if you're looking to be competitive (although with a big enough weapon, servo drive is doable!)
Ants do have a very busy calendar - there's three World Series a year and at least that number of other events, plus the fact they run at just about every heavyweight event too, I don't think any other weight class will get you more battles! :)
