Hit 5 to active the bomb sight. Strap it to the bottom of your plane. Use throttle to dictate pitch: 1 percent throttle is 1 degree: here is a chart of mathmaticaly calculated bomb trajectorys: note some innacuracys may occur due to human error . Keep the plane level:For a 45degree angle at 4,000ft:172 mph. Slow but doableFor 45 at 5000 192 mphFor 45 at 6000 211 mph6000 at 56.25 =263 mphFor45 at 7000= 228 mph. P.s use the closest canera to the rotor and use the other camera as an iron sight. If you like this contraption let me onow and i will calculate more angles altitudes and speeds: cheers!
