No worries, it's only 1:8 scale I'll take it to the beach and play on the dunes :)

And here's me just been reading the Land Reform (Scotland) Act, 2003. in a bid to reduce my ignorance of same and a very nice bit of legislation it is, too. Yes you can cycle, I see that they've made provision for that and you can also ride your horse (excellent stuff) but I'm afraid I'll have to le...

I use 40c Marathon Supremes for riding the Forth & Clyde towpaths, I figure the extra suspension helps smooth out the ride over the railway ballast they used to surface it. No punctures so far in 200 miles, ask me how they are in another 800. They're not cheap but they're holding up well to the ...

Well, thanks for a particularly outstanding response. I didnt expect to end up quite so well informed! That's only because there are too many people on here with too much free time on their hands :) After following the link and chasing down a few more I have only one further question: What on earth...

I think plusses look quite dashing/fetching on a cyclist. I wonder if they still do them with liners ?

My thoughts are a tad different (and I''m sorry if they're wandering, it's the nature of brain storming). I think the frame is acting as half of an unbalanced dipole due to the dynohub grounding through the axle (the other half of the dipole being the hub-lamp wiring. The current from the hub is bei...

dynamo frequency. Can't imagine the coupling effects of a signal at a few hundred hertz (tops) are much to worry about. The VLF aerials submarines use are km along each side and they're in the 10's of khz. (And still crap). A cable wrapped around a magnetic core (fork blade) will couple the field t...

I've the sensor on other fork-leg to dynamo cable. The signal from sensor to computer appears to be fine because I hold the computer off its clamp and it reports correctly. I can even hold the computer near to the light (without touching it and it works). However, when on clamp on bar (other side o...

Just to remind you all that the OP is a novice camper who hasn't yet decided that he wants to take up regular cycle camping. It's important that we point him at cheap, usable equipment that he wont waste a lot of money on if he decides that it's not his cup of tea. Now back to our regular program. :)

This might make it a bit clearer http://i539.photobucket.com/albums/ff360/cranky_50/GTJ03319_2.jpg I think it's a device to stop the chain coming off the rear cog, also look at the chainstay weirdness. The chainstays looks like they're built like a fork running into a single tube at the bottom brack...
