Antweight Resource Page

I've started forming a collection of information on Antweight components and posted them onto the QRSC website. Hoping to get a little repository of information to make it easy to find the correctly spec'd part for antweight designs.

http://qrsc.org.au/wikka.php?wakka=AntweightParts

I'll be adding more during the week

Antweights are 150g.
Plenty of pneumatic bots running around in the UK:

250psi is the pressure limit for antweights under the RFL rules, so if you think you can miniaturize your epic launcher into a 150g design, I say go for it!

bolt.com.au has:
M1.6x5 - $1.12ea
smallparts.com.au has:
Stainless M1.6x5 - $1.34ea or $53.90 per 100.
Stainless M1.6x6 - $0.84ea or $25.30 per 100
Stainless M1.6x12 - $1.14ea or $44.00 per 100.
Stainless M2x10 (Pan) - $0.74ea or $18.70 per 100
Stainless M2x10 (Slotted) - $0.84ea or $25.30 per 100

Nuts...
smallparts has:
Stainless M1.6x1 - $1.54ea or $63.80 per 100
Stainless M2x1.5 - $0.74ea or $13.20 per 100
Steel M2x1.5 - $0.84ea or $17.60 per 100
Nyloc M2x4 - $1.93ea or $102.30 per 100


That's all I could find locally. I recently bought 200x M2.5x8 + matching nuts for around $20 from bolt.com.au. However, I might just purchase a batch of the stainless M2x10 from smallparts now.


EDIT: I've added the screw/nut information from this post to the Antweight Resource Page.

Btw. TG9e is physically exactly the same as the HXT900. Well the new ones are.

Haven't had a close look at electronics yet but I would not be surprised if only difference is the sticker on the side.

Important.
The TG9e does not have the same strength and longevity as the HXT900.
Please ensure your control surfaces are bind-free and always check servos after a hard landing or crash!

Work a bit slow today aaron....

Hmmm yes but I would still say it is likely that exactly the same parts go into both its simpler/cheaper than mould two. Maybe not but the cases appear to come from the same mould.

Also if anyone would like to contribute to the QRSC wiki page PM or email me and I will sort you out with a login. ATM it is locked down to only existing users to prevent spam from nigeria.

It has a cheaper drive circuit which doesn't current limit if the drives encounter resistance, to be honest I don't want it to. The case is simpler than the towerpro servo, squarer and easier to mount. Smile
EDIT: actually marto's right, now they look identical... when did that happen. Laughing

Any chance of the arenas having out of bounds areas to flip into? Or is it all about brushless motors and spinning weapons? Razz

Yes I have bought several lots in the past. It was about 4/5 months ago when they switched over I think.

No size limit. We don't use 4x4x4 cube rule.
