Help in getting in the weight limit.

[Stagfish]

I cant seem to make my ants under 150g, I just cant find light and cheap parts (although I found a 6g reciever and transmitter for £49.99)

Any parts you guys would recommend? I've made two ants in the past, One was 240g and the other was 260g (It had an axe)

[harry hills]

2x 9g servos £5
hitec feather £15
12g 4.8v rx batery £3.50
zebra 3 tx

done.
good luck btw

[jonny]

1mm polycarbonate for armour = £12 for 5 a4 sheets
another more powerful servo for flipper axe=£5-£10 ish
wheels = 10p each off technobots

if you have more money to spend then:

2x 50:1 high power gear motors: £13 ea
2.4ghz giant cod tx and rx: £25
7.4v 2 cell lipo: £3
peter waller speed controller: £35
hs82mg flipper/axe servo: £14 ish
1mm thick polycarb/ carbon fibre/ titanium
polulu posh wheels: £3 each

what components/ armour were your other ants made of?

[Stagfish]

Graham had 3mm polycarbonate (Only rear and bottom armour though, The axe seemed to work well at protecting the front) and Scutlet V3 had wafer thin plastic. Scutlet V3 ran on 4 x AA batteries, two Acoms servos and a Acoms 24Mhz controller and reciever. Graham ran on a 6v NimH battery, 2 speed hacked servos for drive and a normal servo for the axe, a Planet 2.4Ghz controller and reciever. I will post pictures sometime.

[harry hills]

i see your problem, standard sizes servos are much two big for an ant

[AndrewHibberd]

Your batteries are also far to large for an antweight 4 AA batteries weigh about 100g. Look for some 1/3 or 2/3 AAA Nimh batteries which should be ~25g. Or look into lipo batteries which are lighter again but cost more

[razerdave]

Hey Jack, drop me an e-mail at razerdave@hotmail.com, I have a few surplus batteries and other bits that you will find a lot more suitable for ants.

NEVER USE LIPOS
if you have had experiances like me

[harry hills]

i disagree i have just bourght my first lipos for an ant and they are great, with the shorter charging time i feel they are safer than nimhs and nicads, you must have been abusing them.
bumping threads again i see

[team_orr]

i agree with Harry, the only problems i have had is a pack shorting out whilst i was soldering (and even then it just puffed up) or dropping below their minimum charge rate, they are excellent if you use them properly

also Harry, any chance i could buy some of those old nimh batterys off you XD need some and my source has dried up
