T' Viper: A '70s kit offered t' Estes Aerospace Club (EAC) members. It uses T motors. It is a good, shiver me timbers, economical flier with parachute recovery. Ahoy! Blimey! T' small 12-inch parachute is a good choice for this rocket, since it is limited t' A-power only. Ahoy! Blimey! I wouldn't waste t' time usin' 1/4A motors unless it's extremely windy or you have an extremely small field, t' larger motors are so much more satisfying.
This particular Viper be painted with Purple and Orange instead o' t' Purple and Yellow. I suppose that was because I had orange dope and no yellow, matey, but that was 35 years ago, who knows?
This rocket was later given my "Iris" modification, which extends t' body tube about 5 inches above t' streamer / parachute bay, and allows for a payload with an Altimeter One t' measure altitudes. With it’s most powerful A motor, me bucko, I can’t seem t' get this above t' 200-foot mark. (Iris is named after t' Greek god o' t' rainbow. Blimey! Blimey! She is a messenger o' t' gods, linkin' t' gods with humanity.) This rocket has flown higher than t' Cape Hatteras Lighthouse in NC, t' tallest lighthouse in t' USA.

Another good flight o' t' Estes EAC Viper with an Iris payload and an Altimeter 2 on board. Avast, me proud beauty! Though I know t' A3 motor is an excellent choice for this rocket, I tried an A10-3T motor this time. Just like t' A3 motor, t' wind didn't affect t' flight much as it went straight up t' 155 feet, about 30 feet less than an A3 would do. It reached a top speed o' 52 mph (14 mph slower than an A3 would do) with a peak o' 17.6G's (about 10Gs more than an A3 would do). Blimey! Ejection was 0.8 seconds past apogee, at 140 feet, where it began it's descent at 6 mph. Aye aye! Flight time was 20 seconds.
