Twitch RC: RC Car Setup, Tekin RS Tuning

The Must Have app for Tekin RS Users in TC
Specially designed to work with Team Associated TC6

Why Twitch Rc?

I was sick of entering the same information over and over into my phone.... 3.14 * pinion, or was it spur, over spur, or was it pinion... maybe times my internal ratio... only to do it over again for a couple of teeth more or less trying to get the FDR someone else was running...

After finally strapping in that perfect gearing for the car, I'd find that the change in gearing was just enough to fudge my prefect Tekin settings. So Twitch Rc provides the speeds those RPM ranges represent (km/h) given the FDR/Rollout. So when you make a bigger gearing change, take note of the start/end speed values, and then play around with the RPMs to return the start/end speeds to similar values to the previous gearing. Handy when switching motors from 17.5, 13.5, 10.5...

Remembering these values so that when you pull the car out again, you're not pulling the car apart to figure out where you are at. In addition to that, for Tekin RS values (profile, drag, push, boost, start rpm, end rpm, turbo, delay and ramp can be recorded.

Over the holiday I figured I would write a Google Android app to make my life simpler. I showed it to a couple people at my local track, and they said it was better then what they where using (mostly iPhones). I looked into the adding it to the Android Market and here we are...
