First simulations with a Cherokee DD... 
Simulation 1: E12-0/E12-8......2709'......Dv 16 FPS......60" x 1/4" (45" required)
Simulation 2: D12-0/E12-8......2225'......Dv 8 FPS.......60" x 1/4" (47" required)
Simulation 3: E12-0/D12-7......2126'......Dv 31 FPS......60" x 1/4" (43" required)
I figured a lighter design would work better, and these first runs tend to confirm it. It was a pleasant surprise to see a D12-0 doing as well as it did as the booster, and to see a 500' difference in altitude between it and the E12-0. One item to note with these simulations, all three include a 3 oz allowance for a BoosterVision camera and 9V battery. |
