LOC Viper IV Simulation File

I didn't have the original Viper IV simulated, so I went into the dungeon and pulled out the original fins. See attached. There is a big difference at the top end...

I haven't found a suitable high-end "E" or "F" motor that has a suitable time delay. I suppose you could customize a reload delay chain to get the optimum deployment time...

The G55-15 is a sweet motor, though. Four of these park it over 6600'...
