This week I finally got to test changes. I tried the following:

1) Overdrive
2) RCShox 2-stage pistons

1) Overdrive: This didn't really seem to help to much on the tight medium grip indoor track that I am racing on. Since I am planning to swap out the VTS4 for a RCShox V2 center diff I will go back to the 20T. I did notice that my belt was very loose with both pulleys at max tension with the 19T. I got a new belt.

2) RCShox 2-Stage Pistons: I used AE 25wt. rear and AE32.5 wt rear and these worked pretty good. I had a good improvement in handling. I may need to reduce the front oil thickness a little maybe 30wt. What is a good combination of AE oils for yellow springs.

Next I will be overhauling the front diff changing to 7K oil and installing the 20T belt gear. In addition I plan to install the RCShox V2 center diff with 5 pins.

I ran a 4000mAH Shorty pack transverse forward and it performed very well. I used only 2300mAh in a 5 minute heat race and lasted a 7 minute final without any concerns. the car is very light and feels like my 2wd right now. I will weigh it and post later. It seems that a 540 2 pole motr may even work in this chassis now!! There seems to be hope for this car as I am starting to race it more.

I don't have the car running the best yet so I finished 3rd in the B-Main against mainly Losi chassis. I'm not too far from the lead lap. I am really hoping that the c-Diff makes a huge difference. I plan to also go to the 2.2 front sway bar. I have way too much steering and the rear mid corner traction is not good enough. I have the 8mm mod and dropped camber link to 5mm using the outer most hole at the shock tower to get what I needed.

Has anyone tried the longer wheelbase?
