This is my new car, built all by me, when i was making my most recent flying car. I saw the off road challenge and thought, "i bet that i can make a excellent car for this." So, i modified my FC5 to accept the challenge of being an off-road truck. Until i looked at the rules again, did i realize that the challenge was for the trenches of krakabloa, not the proving grounds. So after that, i made better suspension and added vertical stabilizers for better ground handling, and extensive periods of driving and airtime. Anything below a 70 degree climb can be achieved with this truck, but where two 45 degree angles meet, such as on the south side of the proving grounds where the medium sized hill thing is, cannot be done due to wheel postition. The controls are normal, but if you want to go into 4 wheel drive, press 2, and for the really cool auto-stabilization feature, in times like when you are in the air and dont feel level, or when you somehow get upside down, press 1 (only intermittently). if you want to not go fast, take off the fins. Thanks! I spent a lot of time on this fyi. Dont forget about the air tractor challenge!
