Flight Log - 2011-12-04 - 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. Begad! 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. Arrr! (Mine is definitely too heavy t' fly on an A8). Arrr! 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, 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, shiver me timbers, thick coats that would run with normal paints made for a smoother, glossy finish. But by then, me hearties, thar was so much primer and paint on this model that it almost doubled t' weight o' this kit. Begad! In MHO, Rustoleum 2X (from Home Depot) sucks for flyin' models. Aye aye! 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. Well, blow me down! 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, shiver me timbers, 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, ya bilge rat, with a C6-3 it reached 437 feet, and traveled at 89 mph. Avast! That's enough t' have it fly higher than the Great Pyramid o' Giza, now that it has eroded about 25 feet.

Flight Date: 2011-12-04
Rocket Name: X-15
Kit Name: Quest - X-15 {Kit} (2014)
Flyer's Name: Rich DeAngelis
Motors: C6-3
Launch Site: Penn Manor School Lancaster PA
Actual Altitude: 437 Feet

I had high hopes for this seriously heavy X-15. Previous flights in winds demonstrated it will fly well anyways. I ignited a C6-3 that burned for 2.1 seconds, matey, acceleratin' 1.9 Gs and peakin' at 6.8 Gs. Begad! It reached a speed o' 89 mph, still fightin' t' winds and remainin' straight up. Ahoy! There was a 3.1 second coast time and it still kept goin' up despite t' winds!

It then reached it's apogee o' 437 feet - much higher than anticipated. After droppin' back t' 413 feet t' parachute ejected, descendin' under a good chute at 12 mph. T' X-15 landed 28.5 seconds later. Since this model doesn't have a payload, t' Altimeter was clipped t' t' nosecone and it survived OK, but for some reason I did nay get a number for t' time delay betwixt apogee and ejection, all other numbers seemed correct.
