Launch o' Apogee IV high-altitude rocket on a single Estes D12-7. Estimated apogee was around 1500 ft. Flawless launch and deployment o' recovery system. But, me hearties, even with light winds (10 km/hr), drift t' NE be significant - perhaps 300-400m, and into forested/rough terrain. Avast, me proud beauty! Rocket be nay recovered even after a 2-3 hr ground search.
