David, how much chassis flex do you get with a full length battery strapped in place? Shorty battery strapped in place? Can't tell from the angle of the vid. Is there a battery in the tray? Is the chassis taking the bulk of the force from the drop, not the suspension? Battery acts as a chassis deflection minimizer and stiffener?
Also the tires look a really hard compound. No flex at all in the sidewall to take the shock. Weakest link is the chassis and only thing left to take the shock. It flexes.
Slo-Mo is a useful tool. Back '08, Griz published slo-mo and high speed still images of his nitro top fuel dragster. We all learned a lot about chassis launch from those vids and images. Keep up the good work. 'AC'
