The hpx supertec park servo is probably one of the best servos that I know price to stats.
Its one of the quickest servos I know bar some pricey heli servos
Its light
Decent gears, have to really push it to strip the gears
all in all it makes it a good servo :)

I think i might be using that for my ants Flipper, i wasnt sure if there where any better servos out there.

The ant im making has a mini servo in it for its lifter. it wont actually lift anything near the weight of an antweight its just for show on mine at the moment but i might get one of those you linked to.

I was suggested it from David Weston, he uses it in his ant, Stewie.

For the Information, alot of todays Antweight Servo Powered lifter uses the HPX, including my antweight Flippt!. Some exceptions of ants that do not use this type of servo.

Heres the part no for the servo.

I love flippt!
Can i use aluminuim for my ants flipper?

Good thing, now I have a fan! :D

Indeed you can. The only restriction is the armour thickness which is 1mm if its not moving, i.e not part of the weapon. Otherwise its fine.

Se Antweight rules:

+1>2)

j) The maximum thickness of metal armour is 1mm or 0.040 or 18 gauge (+/- 5% tolerance) (there are no thickness limits on non-metallic armour).

k) Armour consisting of one continuous metal plate must not protect more than one third of the robots perimeter (welded plates will be considered as a continuous metal plate).

l) Metal weapons that are more than 1mm thick, and that also provide armour-like protection, must be capable of remote controlled movement (with respect to the rest of the robot) in order to qualify as a weapon.

Great, using metal will beef up my flippers strengh.
Yes, i am a bit of a fan, but im me! (A geek, and W-E-I-R-D, I like cheesy Wotsits in Coke, you get the idea!)

Dont be so modest Joacim your robots are always well designed, built, driven and very difficult to beat.
I have just built my first real flipper and I used fibreglass pcb material for the main lifting surface.

Say, Peter, where do you get the track sytems for ur ants?

They are Tamiya (TAM70100) which gives you various cogs and tension pullies plus a selection of different lenth tracks that can be connected together.
I bought the last lot from here as they are cheap but you can get them in the UK.

Some other Tamiya sets have motor and gearboxes included but they obviously cost more.
I then add some of the sticky rubber on the outside to improve the grip.

Oh, ok.
Just wanted to know incase i wanted a tracked ant.

It says on the page linked to the tracks that they weigh 485g, surely the antweight limit is 150g?

Thats for a large set of them. He cuts them up into antweight size sections which will fit in the limit

Anyone got any experience in overvolting the HPX servos using a two cell lipo?

Do they just go faster or do they start smoking like the HS81

Ive been using 8.4V in Flippt! for ages, and amazinly it still works.
It will both go faster and stronger.

However, you should beware of that you are, like most motors etc., cutting down on the lifespan for it.

Ive been using the HPXF servo with a 2 cell lipo for a while, as has Marco, and the worst Ive done was stripped a gear (Although I did get smoke off the motor in one due to the pot being in the wrong place and full power being on after putting the gearbox back together wrong)
