Ok, so go for a fairly lower mAh then? something in the 2k to 3k region?

[harry hills]

that should see you through a couple of fights.

[typhoon_driver]

3k will do you fine.

Bit confused by that post?

So something like this then Gary: http://cgi.ebay.co.uk/12v-NiMH-3300m...item3353c52b76?

Still confused about the speed controllers too! What specs I should be looking for etc.

6* 125mm Robo Challenge blue wheels

These wheels don't come with nut insert.

Yes they do, if you contact the Robo Challenge guys direct and ask for some to be made up. They don't have them available to order on their webstore though, possibly because not many people use them.
But if he's running Speed 900s he won't need the ones with nut inserts anyway.

Gary, loving how the new version is looking! Will have to have a prod about it for curiosity's sake when I see it

The DX5 on the robo challenge site I'm a bit wary about getting since it's an old model, do they still sell the recievers for them if I were to need a back up?

[RogueTwoRobots]

The DX5e uses DSM2 technology, which means any DSM2 compatible receiver should work with it. Take your pick: http://shop.ebay.co.uk/?_from=R40&_trks ... Categories

I combined mine with one of these handsets when it cost £11.99: http://cgi.ebay.co.uk/Spektrum-Controll ... 3cadc35762
and got a 2.4GHz setup for £22 (which is already more reliable than the Radio Link sets)

That transmitter is very basic though, the DX5e has a lot more to offer.

[Roland]

What exactly does it have to offer? I can't really see anything of importance, probably due to my pure ignorance.

I have 11 tabs open and I refuse to open another so I keep switching from Your build thread to this every five seconds to check if I need to reply to anything!

[RogueTwoRobots]

You know, when tabs were first introduced, I really wasn't keen on them. I don't know why I was being so stubborn but I just refused to use them. Love them now though, had an insane number of them open when trying to compare hotels and book rooms for the upcoming FW champs!

Anyway, I've just had a quick look at the DX5e specs and it doesn't actually have that much extra compared to that transmitter I linked to (the E-Flite). They both have servo reversing functions and dual rates, although they'll probably be adjustable on the DX5e, don't think you can do that with the E-Flite. The main differences are that the DX5e has an extra channel and built-in mixing. Being used to standard transmitters such as Futaba, I found the E-Flite one to be really plasticy and cheap (to be expected at that price though) and the sticks felt very loose to move. But I tried driving Drumroll with it and it felt perfectly fine with a similar response to every other transmitter I've used. It's up to you though, I'd say the DX5e feels more like a proper radio transmitter but if you're not too fussed by things like that, then the E-Flite for £15 would do the job.

[Roland]

I can't see how you've got the drum on drumroll spinning? There's nothing connecting it to the motor!

Talking of chains, would a cog and chain (What's the technical term?) Be more efficient supplying the other wheels than a belt and sprockets?

Thanks for your help so far guys, you've all been amazingly helpful and I know it's cliche but thanks for using your own time to answer my questions!

Edit: Sorry I didn't see your post Jamie! Hmm, I think also that if I get a DX5e it'll last me longer, and therefore will end up being a better buy, by mixing do you mean you can change the drive type? Or max speed of the motors?
