Run my T2 007' today again, with IB4200WC (1 year old) 5cell packs, still the same Nosram TC-Spec ESC and SpeedPassion 3.5R motor. Increae 1T on the pinion (20/112T) and make the final gear ration to 1:9.52, with front spool setting. Change to Tamiya yellow springs all around and use more ackerman angle on steering setup. I also remove most of the additional screws on upper and lower deck and remove all the side posts - to allow the max "flex" on my chassis (out door track).
Performance is good - I like it better than original setup with one-way and front harder / rear softer springs. Car is much faster with this gear ratio and the ESC does not encounter any overheat shutdown ... yet.
It was a very good and enjoyable weekend for RC here in Singapore.

Running my T2 007' in the past few weekends. Running front spool with 5cell, Nosram Brushless ESC (same as LRP TC Spec) and a SpeedPassion 3.5R motor. Gear ratio at around 1:10.02. My first chassis to use Spektrum rx. I have to remove a lot of screws (including all the side stands) from upper and lower deck to allow more flex on the chassis - better on handling with the "soft" chassis setup.
