for the price between the dx5e and dx6i it's best to get a mixer they're only £10

So is Delta mixing the sort we use to get tank steer on one stick?

There must be a way round the half power problem......

Re: Team Thrifty /Fifty Build Diary for Bitza

I think delta steering is on one stick eg forward, back, left, right.

Re: Team Thrifty /Fifty Build Diary for Bitza

do u have any photos of the inside of bitza?

Re: Team Thrifty /Fifty Build Diary for Bitza

You can check the photo bucket page, but I don't think so....

The lighting is pretty crap in the workshop in winter so all internal shots came out like muddy blobs.

I'll try and get some of Bitza next time i'm in the work shop and other Bitza 2 when we start building.

What is the best way to bend Titanium?

I've managed to come into some Grade 5 (Ti6A) Ti (don't worry it's an off cut, so still Bitza esque...) that I want to use on my Beetle, but I'm concerned it will crack if I bend it without heat?

It's 2mm thick, and I need to do a 90degree bend along a 40mm section (possible longer sections if I can afford the weight).

I've got some Cobalt drill bits to machine it, but not too sure the best way to cut it? Angle Grinder?

Thanks!

Re: Team Thrifty /Fifty Build Diary for Bitza

my sponsors do all my ti stuff i think grade 5 will bend with ti if it bends it will if its designed not to then it will crack

easiest way to cut is on a guillotine but ive used angle grinder before

to bend it my sponsors use a piece of equipment to do it you can get exact angles best way id say

Cheers for the advise.

Will it bend, that is the question?

What is the best way to attach a pulley to a motor shaft?

Just bought a brushless for my Beetle, it has a shaft diameter of just over 3mm and is completely smooth. The timing pulley just has a pilot hole.

The motor is an outrunner, and Ewan advised bolting onto the casing (since that also rotates) but I could do with some more detail.

Any suggestions?

Thanks,

PJ

Re: Team Thrifty /Fifty Build Diary for Bitza

drill the pulley out to 3mm. Drill and tap a grub screw hole to intersect this hole. File a very small flat onto the motor shaft. Mount using the non rotating face of the motor, slide the pulley on and tighten the grub.

Re: Team Thrifty /Fifty Build Diary for Bitza

Id say do what gary suggests.. If you dont have any drills and taps small enough for a grub screw, get some high grade loctite, and loctite the pulley onto the shaft... I did this for the gears in 360's first stage disc drive and it worked fine... thats putting much more tourque through the pulley then you will be able to generate... It just makes removing the pulley a pain.

I wouldnt suggest mounting it of the rear of the motor if you can help it- its asking a lot of the bearings in the front plate of the motor over that sort of distance.

As for the ti- try it... the term grade 5 is pretty open.... put it in a vice, try bend it over with a hammer, if it cracks, try heating it ... you will need to get it cherry red until the point that the surface of the titanium looks like its gone flakey before you will be able to bend it easy.... Wear some welding gogles if you've got some while heating it.
