Re: Team Bitza

Good find Chris!

That's a good point Mario but I've really only a need for one fan, worth bearing in mind though.

If you have the weight left, a second fan probably is cheaper than any solution involving step-down.

But, what are the stats of the fan? Size, powerconsumption and such

Re: Team Bitza

Currently plan on using a PC fan, which is perhaps a bit too big (let alone 2). Their use it cooling ESCs so your Victor ones could be perfect!

Re: Team Bitza

build your own, thats what i do in laser to regulate the voltage.
a quick search on the internet will find you all the parts and pop down to maplin and they should have all the components. dead easy to assemble and a lot cheaper then buying ready built circuits.

Re: Team Bitza

I'll try and get the dimensions for the fan tomorrow and you can see if it will fit.

Re: Team Bitza

Cheers Dave!

That's true Ben, but for £1.50 it would be cheaper to buy one. Maybe if I wanted a project!

Re: Team Bitza

BitzaWood Revo now has a proper disk. Dan turned it down from the master pulley of a V6 Mondeo and added tool steel teeth.
Video to follow!

Re: Team Bitza

That looks seriously nasty! That tooth is huge!!! Top speed? Weight?

Re: Team Bitza

Nice! would like to see the video of it in action
...just a small observation - wouldn't the tooth be more effective if it were fixed with the sharp edge facing outwards?

Re: Team Bitza

@Liftoff, I'm not quite sure I know what you mean? The sharp edge of the tooth is at the very edge of the radius.
Dan then machined a gradual radius on the outside of the tooth so as much mass as possible is away from the centre and behind the sharp edge without protruding beyond the maximum diameter.

@Eventorizon about 3000rpm 2.5kgs. The setup was originally for those wood saws, for which I didn't want a huge amount of top speed.
The plan is to do a voltage upgrade to 6s which should double the RPM.

Re: Team Bitza

That looks seriously nasty. One day you have to build a featherweight K2!

[Liftoff]

Re: Team Bitza

I see what you mean, the radius on the outside of the tooth is at a tangent to the pulley - looking back at the photos its clear... That machine will cause some serious amount of damage!

Re: Team Bitza

It packs a decent amount of punch for a rather small diameter.
The disk is good but the rest is pretty flawed!

I like the look of K2, a similar low profile design is what I was thinking for the re-design. Reluctant to start though, don't know if I'll have time before April.

Re: Team Bitza

Give it to me, I'll do it I'll do it!

Haha, good luck. Post pictures of whatever you make.

Re: Team Bitza

Haha, well I have all the components! Just need to make the chassis and bolt it together.

Re: Team Bitza

erm, K2 ?
