Sorry guys i've not been updating the thread
So things are moving on, i ordered a 3racing diff.
This helped a little bit but the car was still pretty much undrivable for my poor driving skills.
While i was at it i also ordered the M05 fast gear set from 3racing.
I refitted the stock Esc and 540 motor and installed the 33/21 spur gear.
I don't have any Tamiya pitch gears so i went through my standard 48P pinion gears and found that a 28T pinion in the 21T mounting hole fitted perfectly.
I did some calculations and found that on the standard 21/37 with my brushless motor spinning at 21600rpm i would see a max speed of 26.13mph.
With the new 28/33 i should see 39.06mph.
So in theory the new gearing should dramatically improve slow speed acceleration control.
I took it out for a spin and it was the best it's been.
It still has a tendency to snap rather than slide if the rear steps out, but when it does step out it gives you a lot more time to do something about it.
Everything was going great but i kept seeing the car kick up dust.
To be honest as it's Greek roads i didn't think to much about it at first.
I then realised it's not stopped raining in 3 days so there should not be any dust
I bent down to have a look at the car and found smoke coming out from under the shell
I removed the shell, disconnected and removed the battery and let the car stand for 15 mins.
15 mins later i saw the smoke had beeen coming from the motor, so i did the old "i wonder if it's still hot" test of touching it
Yep it was still hot.
I've since refitted the 9T brushless motor, so fingers crossed this'll be able to pull the gearing better than the old 540 (without over heating).
Weird thing is though when the motor was smoking the Esc was only warm to the touch
So i'll test it with the 9T and we'll see.
I know that standard 48P are not exactly the same as Tamiya 48P, but i figured i'd test it this way till the gear wears and if it's ok i'll then invest in some new spurs and pinions.
The wheels and tyres i ordered arrived as well, so i'll glue those tomorrow and i'm sure they'll help a hell of a lot, as the slicks are really soft and sticky.
I'll let you know how i get on with the 9T motor and new tyres.
Better take a fire extinguisher just in case
