TOPIC:

Is the Baja gearbox a worm & wheel type? - how does it get on with freewheeling on the overrun? Just remembering stories of how a similarly geared electric car used to stop dead when you let off the throttle (Bolink Digger?)

Sorry, can't get excited about nitro cars, for me they have similar appeal to a bucket of sump oil with the contents of the cat's sand box dumped in it! You could say I'm not a fan, although it's nice to see a vintage one being lovingly restored, & I find it interesting to see how vintage mechanical stuff was done

just started reading this thread what a nice car its great how a new bodyshell finishes a car off so great looks ace

I'm glad you like, I just need to complete some real world projects and that should free up some time to work on this

Yes it's a worm and wheel (thought i'd posted a pic of the internals ) With it being nitro, the engine has a centrifugal bell clutch like a chainsaw (or similar) so unless it's under power it runs free

That's what makes us individual I like that not everyone likes exactly the same thing, that's how we have ended up with such a broad range of techniques / finishes and cars here I have to admit that nitro cars are painful, however like you I do marvel at the engineering especially the vintage ones andy..

(sorry this was the only pic i could find)

Ahh, looking at the pic 50 & 51 look like crossed helical gears, not worm & wheel, explains why it can freewheel.
Are 44+42 acting on 41 as a brake? Or is 44 just a throttle relay?
Castings are chunky!

Your right crossed helical it is yeah 44 is just a throttle link, I think this is a hop up as I haven't seen it on any car, it may depend on the type of engine? I like it as a technical add and might manufacture 1 to put on just cause Mine came with a really long throttle rod which ended up too flexy.

Finally made some progress on this I trimmed out the radio box to accept the gearbox mount plates, since I don't want to modify them. It sits back perfectly to allow space for the steering linkage rods and the wheels in full lock I also put 2 slits at the back of the top cover for it to fit. I don't plan on painting the box, so you will see all the components plus i'll leave the protective film on until finished

Ordered up some Alloy body posts for the beastie, they are anodized blue, but i'll remove that and polish them up nice only problem is I received a message from the supplier today who said it could take 3-6 weeks for them to arrive

I love the little muffler, looks the part.
You're luck it's in such good nick, mustn't have had much use and nothing appears broken.

So the Nanda BD8sc-e 1/8 as I mentioned in the "exercising the dog" topic I ordered a nice new motor and esc to handle the 2 5200mah 7.2v lipos I picked for it Well they arrived tonight but unfortunately I forgot to check the motor dimensions It is to big to fit in the stock cradle and location Now ordered a new center mount assembly to deal with that but I want go fast now!

So after spending hours trying to wedge the Flux gear in to this, it just wasn't meant to be So another combo with a shorter motor and she just squeezes in Just need to sort the top brace plate and I'm good to go Oh and to help my therapy I ordered a new body too
