Of course. What else?
The "engineering" solution to this would be to use left-hand threads, like on the cranks of your bicycle, or the crankshaft of your 1:1 car.
But maybe a high nut with fresh nyloc would do.

but surely it gets big 'kicks' in both directions, especially in the air

That might be what does it Chris. If you think about it in a normal car when you accelerate the nut's inertia is trying to loosen it, and when you slam the brakes in the air the shock will want to tighten it.
With the reverse gearbox it's the other way round, the nut wants to tighten under acceleration and the sudden deceleration happening when you correct the car in the air is in the loosening rotation/direction. (I have a feeling that will be grammarated :confused: :p )

but what about when you gun it in the air, using a normal 'box ?

I think big nuts will only make the problem worse, a light nut wouldn't have that much inertia like a heavy one and might not have the problem...

The biggest kicks are in the direction of 'tighter' on a normal standard non-reverse-tranny B4 box.

Transmissions get the biggest whacks when landing (full-throttle- off of jumps, and when slamming the brakes.
Any motor, brushed or brushless, can bring a car to a dead stop faster than it can accellerate it to top speed. Same with disc brakes on a 1:1 car. Braking is always faster than accelleration. That's why the 'ideal' line is asymmetrical.

And Coop, I said 'higher' nut (with more nyloc), not bigger nut. YOU are the biggest nut :-O


That being said, why does the diff screw go in from the other side on a B4 compared to a Losi? :confused:

adjust the slipper to how you want it, then put a bit of lock thread on the thread( obviously) ;)

The Losi has a WAY bigger and heavier screw, the AE screw is very 'thin' so less inertia...

hey nutty Smellvo, check THE directory, added *cough*3D*cough* slipper to the tranny.

Yea ben thats what i was thinking.

broken ?

lol, more like stripped so he could build his B4 back up. i think you sold the xxxcr today as well richard ? back to the good old b4!! :p:p

Yup :p

It was pretty poor I'm afraid, it did a couple of things really well but lots of things badly. It was so far off the pace I don't think it was a setup issue, it was just rubbish :rolleyes:

thats a shame Rich, I had a look at the car in person, was very good quality;) I think with my project, I will leave the tranny as norm, and mess with the chassis

'It was so far off the pace I don't think it was a setup issue' ...

... but it was quick enough to win :D

I was talking about my mid-motor thingymebob :p

oops :confused:

The thing is i am sure losi and AE will of tried all sorts of weird and wonderful configurations when designing the cars, as richard has said it was off the pace but it was just a project for him and something to try, if it worked great, but the chances of one man outwitting ae and losi is pretty slim.

no offence meant to anyone here, im sure there are some very clever people in this game and projects are great and very interesting to see but if losi or ae thought it would be better this way or that then i am sure we would see different cars, as it is to the untrained eye there would be very little to seperate the cars.

YEah minimum is really 2, as Jconcepts are world champs:D

very good point,;) but the 2wd mid motor idea was about when the cougar 2000 was around and hasnt taken of since (on a big scale)
