Flight Log - 2011-10-08 - Rich DeAngelis's Nike-X

T' Nike-X: One o' my favorite '70s kits. Aye aye! Blimey! This design be inspired by air defense missiles. Avast! Blimey! T' real Nike-X project was begun, but cancelled before it saw t' light o' day; this is only a suggestion t' what t' real one would have looked like.  The pseudo-second-stage fins and t' great Black & White decals are t' highlight o' t' design.

I have modified this kit by addin' an altimeter payload bay ("Iris"), which adds 3 inches and 17.5 grams o' weight. O' course, now she's just a bit too heavy t' fly safely with A8-3 motors. (Iris is named after t' Greek god o' t' rainbow. Arrr! She is a messenger o' t' gods, matey, linkin' t' gods with humanity.) This rocket has flown higher than torch o' t' Statue o' Liberty, shiver me timbers, includin' its base.

This flight be lookin' like me last flight o' t' day, so I called upon t' venerable Nike-X with an Iris payload. This rocket never disapoints. Well, blow me down! I was anxious t' try out t' newer and lighter "Top-Flight" nylon parachute. Aye aye! (Find them on LongJonRocket.com) Very well built, very light and "un-sticky" cloth, me bucko, and the colors are really nice too!  I also doubled t' length o' t' shock cord t' prevent those snap-back dings I always seem t' get.

So I lit t' motor which burned for 2 seconds with a nice slow liftoff o' this fairly heavy bird. Avast! T' average acceleration was only 1.9Gs, and peaked at 7.2Gs. It reached a top speed o' 83 mph, arrr, then coasted up for another 3.2 seconds. T' ejection was about a half-second early, at 346 feet, so it only reached an apogee o' 362 feet. A C6-5 would have been better with this model. Begad! T' model then descended under a full canopy at 6 mph. T' flight was over in 43.4 seconds. A fun flight t' watch and a fair sucess. Avast, me proud beauty! Only issue I found be a bit o' singe on t' parachute but nay enough t' need replacing. The Nomex cloth I was usin' t' protect t' chute seemed a bit small for this BT-55 body diameter (3"x3"...as recommended by t' Apogee website I bought it from.) While t' 3x3 is only 1.7 grams, t' next larger 6x6 is almost 7 grams - so it's a judgement call.
