T.O.P. Racing "Photon" 1/10 EP Touring Car

so I used a uPro Gear diff for the first time... and I found the diff action to be very light.. so much so that when I came back off the track I found that the outer (left) tyre was very worn.. (track is mostly right turns) - I can only assume that the outside wheel was unloaded and getting 100% of the power... and just spinning most of the way down the straights..
How do you guys know what is a good diff action/feel? I used to run Nitro and would run anywhere between 10k to 30-50k depending on grip levels..
I have rebuilt the diff - and now when I put the car up on the pit stand.. and if turn a single wheel.. it will also turn the front wheels.. whereas the uPro diff out of the packet was so light that it would not turn the front wheels.. and only turn it's opposite..
Thanks anthony.

Big Props to Larry Fairtrace for taking it down in 17.5 Touring car at "The Gates" Halloween classic. I believe there were more than 50 people in that class. Larry took TQ honors also. As if that wasnt enough he decided to pull out his 13.5 Boosted 1/12 scale and continue his Domination from IIC. He also Tq'ed and Won that class against some big names.

Started off with the IIC setup on my Photon. By the end of the 2nd round I was back to the standard carpet setup I have been running at most races in the last 2 years.
I just fine tuned saucing from there and the car was awesome.
Competition was tight and Hanyes was relentless in the main. I made one tap and lost my lead and couldnt get it back. It was another in a series of good races between Haynes and I.
The Good ole Photon is still a very fast.

I also have the rebuild kit for the uPro and in the instructions it recommends using diff oil not less than 20k - I'm not saying that your are wrong by using 2k or anything... just fyi -
#8426
Replace them. I have heard of people using the thick oil if they are using it in the front, but as for the rear 1k or 2k all day

Larry,
Have you ever tried running a long wheelbase (F all shims back, R all shims forward?
I checked other manufactures cars and the Photon with the way most people set it up is 5mm shorter.
I extended it out and was about 2 tenths faster on average. Car was way easier to drive and more consistent. I can see the benefits of running a shorter wheelbase i was just wondering it you've given it a try, where you faster or slower?
