Previously, I’ve blogged about the issues I’ve had getting 4Gb of RAM to work successfully in my unibody 15″ MacBook Pro. For a while, I ran with 3Gb using an original 1Gb and one of my new 2Gb sticks, but it wasn’t ideal for running Windows under VMWare at the same time as other stuff. In the end, I’ve given in and just bought the 4Gb RAM upgrade from Apple – not cheap, not ideal, but at least now it’s – so far – working. I definitely think that Apple should have taken more ownership of this problem, as it’s been reported and discussed at some length on their support boards, though.

As blogged earlier, I’ve recently decided to give radio-controlled touring cars a try. I’m starting out with the Xray T2R Pro 1/10 Touring Car. I’m classing this as “a beginner’s experience” as I’ve never built one of these before – I’ve built a rock crawler recently, and a Tamiya kit many years ago, but this is in an altogether different league.

In the first of a short series of posts talking about how I built the kit, I’ll go over the stuff you need to buy to be able to build the kit. continue reading…

As expected, Apple recently announced the next iPhone – the unexcitingly-named “iPhone 3GS”, the “S” apparently meaning “Speed”. Of course, the question on everyone’s mind now is… is it worth getting?

In short, I’m going to go with “no” if you already have the 3G, and “yes” if you still have the first iPhone, or indeed don’t have one at all. Read on to find out why… continue reading…

Spektrum DX3S transmitter

Spektrum DX3S transmitter

After unpacking, charging up the batteries and checking everything worked, the first thing I wanted to do with my new E-Revo was replace the radio gear. Don’t get me wrong – the transmitter and receiver that come with the model are fine, and I’ve not read any complaints about them, but since I bought a Spektrum DX3S for my touring car, I’d much rather use that.

The main benefit of using the DX3S is that it’s a 2.4GHz system – so it should have a greater range, and no risk of interference from other transmitters. There are other benefits too – it only needs 4 batteries, not 8, and since has a 10-model memory, I can set it up to work with the E-Revo and the T2R Pro straight away using the two receivers it came with, and by picking up another receiver I can  control the AX10 with it as well. I might even use it for the boat – one transmitter for all my non-flying models…

Anyway, the point of this post is to describe how I got everything set up to use the DX3S with the Traxxas E-Revo, so let’s crack on.

Looks like a fair bit of traffic hitting my site from people Googling “T2R Pro”, but getting the main page instead of the posts being referenced. So here’s links to the relevant posts – there’s more to come now I’ve built it and got some pointers, so check back soon!

Traxxas E-Revo

Traxxas E-Revo

Over the last year or so I’ve been getting back into radio controlled stuff , and have been building up a collection of helicopters and cars that I never could have managed when I was a kid.

As you might be able to tell from other posts on this blog, I already have an Axial AX10 Scorpion rock crawler, and an Xray T2R Pro 1/10 touring car. But… I wanted another one. Why? Put simply, I want one for bashing. The T2R is only usable on a racetrack, and although the AX10 is great fun on rocks, it’s a bit too slow for any other scenario. For general messing around in the garden or elsewhere, I wanted something with a bit more grunt, so I started looking around.

What to choose?
