Looks absolutely great Peter :) not looking forward to having to fight it, hehe...

How are the idler wheels for the tracks held on, it looks like a shaft stub into a bit of circuit board held in the chassis?

The stub axels are 3mm carbonfibre glued into moulded tubular axel holders.
The fibre glass support was just to introduce a bit more stiffening where it meets the wall.

I am beginning to have doubts about this motor being strong enough to use in a spinner.
Image
I think I over came the mounting problems by recessing the thin mounting legs into the fibre glass base to give extra support but the shaft at only 1.5mm seems very thin and as soon as I tighten the grubscrews that hold the blade on the motor case distorts causing the magnets to scrape.

Finally gave up with the small motor at least for the present.
New version of Flebite with more of the weight over the wheels but it is still prone to skating about when the spinner is running.

Very nice Pete :) I'm interested to see how it drives with those prongs on the front. It looks a bit steep an angle to me.

I know what you mean they are a little steep but the photo makes them look worse than they are.
Here is a better shot and I can still bend them a bit more if it is a problem on rough arena's.

As I mentioned in my post on the Antweight thread, I am in the process of reviving my current team with shapeways, and this included a fleaweight I have long been planning.

So here is Salt in his current state

Image

Hes running off one of Peter's fantastic speedo/rx boards, but to make it fit we had to take off the casing, clip off the connectors and solder most of the wires directly to the board. The two lipo cells fit in on top of it to power him, and his drive is 4 antweight size gearmotors. As you can see fitting the cells in is a very tight squeeze. No idea how we are getting the battery connector in, a smaller plug is most likely needed.

Image

He is 13mm thick!

£5 on that winning the next FWS
Incredible you've got a great antweight drive into 75g. Well done, I hope you do well with it.

You must have a very small shoe horn to have got that lot in there. :roll:

Rather than have a battery connector, do you have space for a pair of pins (like on a receiver) ? You can hardwire the battery in and use a pin jumper to turn it on and a socket on your charger that fits to charge it.
