Flight Log - 2012-06-10 - Rich DeAngelis's X-15

 

T' X-15: This is a "Sport-Scale" (not true scale) model o' t' famous X-15 rocket-powered research plane. Ahoy! This particular kit appears t' be newer than other Quest X-15 kits described here: It is a few inches longer, and a recommendation by Quest t' only use t' A8-3 or A6 motors. (Mine is definitely too heavy t' fly on an A8). Well, blow me down! I chose t' paint me particular model gloss blue (not t' historically accurate black).

 

My kit came out pretty heavy as I used a full-sized can of Rustoleum 2X paint tryin' t' get a smooth, arrr, glossy finish. Apparently light coats o' this paint leave t' finish in somethin' like an orange-peel texture, cool but nay good for low drag. I discovered heavy, thick coats that would run with normal paints made for a smoother, glossy finish. But by then, thar be so much primer and paint on this model that it almost doubled t' weight o' this kit. In MHO, Rustoleum 2X (from Home Depot) sucks for flyin' models. Blimey! I wish I would have used t' ridiculously expensive yet lighter Testors stuff at $5 for a tiny 3-oz. can.

T' X-15 finally got a payload section addition. This adds another 3 inches t' t' rockets overall length. Arrr! Blimey! This will hold t' Altimeter Two, which no longer is at risk o' ejection shock damage or loss if t' clip fails.  T' added bulkhead, painted payload tube and paddin' only adds an additional 13.6 grams o' weight t' this model.

She flies well and is nay affected by t' wind much, though I wish I could get her t' venture a little closer t' t' clouds.  Actual measurements with an altimeter on board shows this model can go much higher than I estimated, with a C6-3 it reached 437 feet, and traveled at 89 mph. That's enough t' have it fly higher than the Great Pyramid o' Giza, arrr, now that it has eroded about 25 feet.

Flight Date: 2012-06-10
Rocket Name: X-15
Kit Name: Quest - X-15 {Kit} (2014)
Flyer's Name: Rich DeAngelis
Motors: B6-4
Launch Site: Halifax, PA
Actual Altitude: 149 Feet

I needed t' test this model with a B6 motor some more. T' last B6 flight with a -2 delay was clearly nay enough so for this flight t' B6-4 be t' be tested.
T' liftoff was brisk, with accelerations higher than previously recorded for this rocket, peakin' at 8.4 Gs and averagin' 3.4Gs for t' 8/10 second burn.  This model then reached a top speed o' 56 mph. Well, blow me down! T' actual delay was a full second short and occurred at 127 feet.  After 1/10 second it reached an apogee o' 149 feet (one foot higher than t' previous flight) with t' parachute still in t' tube.  T' rocket continued down for a nervously long time with only t' nose cone out, appearin' t' be headin' for disaster.
Eventually t' ‘chute was pulled out in t' turbulence and it opened.  T' model descended at 12 mph and landed about 50 feet away. Begad! Flight time was only 11 seconds. Avast, me proud beauty! As I expected, flights with this model would be much more impressive with a C6 motor, B6’s are hardly worth t' effort.
