Individually they weigh 3.2g each, but if you add the 4 screws to attach a wheel they weigh 4.6g each, this would be plus whatever wheel you decide to add to them.

In comparison the small pololu wheels(about 30mm) weigh 3.2g each.

so they're quite a bit heavier than using the polulu wheels once you've attached a wheel to them, but they do give you more freedom when it comes to what size wheel you use

Yeah, that's pretty good. I never really have a problem with weight. Not on the robots at least!

Looking for some advice on 2.4Ghz transmitters. I bought a DX6i a few years ago, but the price now is a lot more than I paid. Does anyone have any recommendations for a reasonable priced transmitter?

I am also looking some a cheap brushless esc. Robotbirds do a 6A one, has anyone tried this on 3 cells?

Thanks

I used these as wheels on "El Chupacabra",and they now reside on Raoul. They are great. I have drilled holes in mine,(to increase aerodynamics. )

I also used a pair of these as cams on the elastic axe thing.

If you don't mind doing a little soldering, I'd go on eBay and get hold of an old Skysport/Field Force 6 transmitter for roughly £10, buy a FrSky conversion kit and receiver for about £25 from GiantCod, wire it all together and get a 2.4GHz transmitter/receiver for £35-£40.

Some conversion kits have had their issues (my old Corona one, for instance) but myself and a few others have never had any problems with the FrSky conversion kit. The benefit as well is that all the transmitter functions (model memory, dual rates etc) are retained and can be used with the 2.4GHz kit in the same way as they were when the transmitter was operating on 35/40MHz.

A link for the conversion module and an 8ch receiver:

Just had a quick search on eBay and there are plenty of transmitters coming up cheap.

Interesting piece of kit. My old tx was a futaba 6exa, a quick search has said this should work on that. Has anyone tried this with the rx31 receivers?
Thanks

EDIT:

Looks like these will only work with the rx's they manufacture, I don't really want to have to buy more rx's to fit into the robots...

Jim, I still want to see that in the arena sometime!

And that's just given me an idea, those hubs are perfect to make a very simple walking mechanism. Just like the one I had on Egg 2 Brutus but even easier!

LOL. One day!

I am going to put a diode in parallel with my solenoid valves on anticide, however typical packages for 1n4001 diodes are huge compared to the valve. Is there a smaller package available or does anyone have any other recommendations?

Thanks

[BeligerAnt]

For axial-leaded diodes you could look at the 1N4148 (aka 1N914), be careful though, it's a signal diode so I'm not sure about how much forward current or reverse voltage it can handle.
The only smaller alternative would be surface-mount SOT-23 or similar, although they might be tricky to mount without adding more size/weight than a 1N4001
