Whipper tuning shot 150:1 mass ratio

Shortened the sling 1 inch. Front loaded 145#, back loaded 125#, +the hanger 20# for a total of 290# and a 1.94# pumpkin. 150:1 mass ratio. 12 second hang time. Results show the back pull of the arm at stall was eliminated along with the stall. Good energy transfer. High launch angle, and very high launch. So high in fact that I couldn't even see it anymore. Next task is to drop the launch angle, and pull the arm further over the top by closing the gap a few degrees, dropping the cw further behind bottom deadcenter and give it some finger angle...Adding pin angle might bring the stall back. not that that's a bad thing... Fine tuning
