UPDATES: I took this truck out form under the bench today. Dusted it off and ordered some parts form tower for it. I started on a longer and wider chassis for it. I plan to now use 2 separate servos for the two engines throttle. the other set up was just not working correctly. The new chassis is thicker aluminum and roughly 2 in longer and 2 in wider. Pics tommarow. And I agree my english is a little bad.
