Hi guys,
Updating the build log, I had some goodies arrive
lets get into that shortly
So a few issues I was facing on the second run - I got the whole drive running much smoother by adjusting the rear diff position (its really tight on clearance, about 1mm at the bottom and 2mm on top) so now it rolls very smooth with no pinion in place.
I also tried out a 10.5t motor to get better throttle control but even with that I had to have a massive expo curve (about +50) or VTR. Seems like low end throttle control is very very important for this build.
The car was running better, but I still had some major tuning tweaks needed. The big thing I noticed was the drop in speed when hitting full lock. The wheels were not binding at all but just the whole front configuration was not very good.
I ended up setting the camber to 0 from -5 and that helped, I then made the front suspension stiffer 5 turns at a time until it started responding better. By the end of the day I was able to get around our track using less and less gyro but still not the best setup.
SO to counter some of these issues, I ordered some overdose rear arms for more suspension mounting options on the rear. Some new low scrub front knuckles to tackle the steering and speed drop. And a 12t main drive gear for better throttle control.
Heres some pics
These are the new dedicated D-165 Yokomo RWD hubs
Heres the fitting - ive re-adjusted the shock positions to be vertical and in doing so I can remove the upper spacers causing some nasty angle.
Here are the overdose rear arms, I can now mount the shocks on the shock tower holes and they are much softer! huza
Here you can see just how little room there is for the rear diff
Here you can see the 12t main drive gear - because the belt is so loose I have to add the tensioner back in. Its not mounted brilliantly but its works for now - I plan to dremel out the top plastic section to allow the belt to have more clearance.
And just for coverage!
Will keep updating as I go but lets hope these few updates make a big change.
Thanks again for reading and stay tuned
