i broke it

[audia4]

well i was relly looking 4ward to using the tl01, with her new wheels and tyres, and lightweight chassis, but 5 mins in of going very fast indeed, and a nasty grinding noise appeared from the rear gbox, so stripped it down and found this, my new lightweight chassis melted around one of the gear shaft holes. not happy! =(

That's strange - that would sort of suggest that the shaft itself was turning. Did you use bearings on the shafts? Apparently the lightweight chassis isn't really worth using - the material isn't strong enough. When you rebuild it, I'd recommend using carbon fibre gear shafts too - you can make them yourself from a kite spar (ask for an offcut from a kite shop - 5mm, hollow IIRC)...

hi, it seems they were the only standard bronze bearings left to replace in the whole car, oops, nevamind gotta get 2 more ball bearings for it and a new chassis as the old one isnt much better, i was going to get the carbon gearshafts too, was really impressed with the pace off the thing till it went wrong. another trip to the modelshop. =) heres a sneaky pic

Before you do any serious running of TL01, it should have full bearings - you need 24x 1150.

Tamiya gives 2 bronze bushings for the spurgear... but if you

under OR overgrease it, it will seize onto the shaft

and overheat the shaft = melted chassis plastic.

Very common TL01 failure.

Carbon shafts doesn't fix it, save your $.

Lightweight chassis or not, both melt the same.

Lightweight chassis isn't recommended for offroad TL01/B use

but its still plenty strong.

I was suggesting making them for free - I've got a homemade propshaft and gearshafts in mine, which work a treat. Might not fix the problem, but if the car is going to be dismantled, might aswell put them in...

yeah i will get the carbon shafts, they are cheap and i only need 2 bearings and a new chassis, and then it will be like new again, but fast. =)

5mm carbon Kite spars eh?

Nice tip, will have to drop into a kite shop one day.

(and hopefully walk out WITHOUT buying a u-beaut box kite... [])

I've been cutting TL01 shafts from K&S bronze & ally tube.

Anything would be lighter than the depleted plutonium that T uses. []

I couldn't believe how heavy it was when I first took it out (I didn't build the car in the first place)...

I got some offcuts for peanuts, but you can buy decent lengths for much cheaper than taimya (or eBay) prices:
