Flight Log - 2012-02-05 - 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. 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). 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. Blimey! Apparently light coats o' this paint leave t' finish in somethin' like an orange-peel texture, cool but nay good for low drag. Begad! I discovered heavy, arrr, thick coats that would run with normal paints made for a smoother, glossy finish. Ya scallywag! But by then, arrr, 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. Ahoy! I wish I would have used t' ridiculously expensive yet lighter Testors stuff at $5 for a tiny 3-oz. Begad! can.

T' X-15 finally got a payload section addition. Aye aye! This adds another 3 inches t' t' rockets overall length. This will hold t' Altimeter Two, arrr, 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, me hearties, 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, now that it has eroded about 25 feet.

Flight Date: 2012-02-05
Rocket Name: X-15
Kit Name: Quest - X-15 {Kit} (2014)
Flyer's Name: Rich DeAngelis
Motors: B6-2
Launch Site: Penn Manor School Lancaster PA
Actual Altitude: 148 Feet

On this fairly windy and cold day, I could count on this rocket t' fight t' winds and fly upwards and nay disappoint. Arrr! I was nay sure if t' cold would keep t' parachute from unfoldin' or not, as me previous flights this day had all came down under a plastic wad. Aye aye! I was usin' a B6-2 in case it arched over a lot. Well, blow me down! This is it's first B6 flight with an altimeter. Well, blow me down! It burned for 1 second and accelerated t' a peak o' 6.5 Gs, averagin' 2.3 Gs durin' t' boost. After that it reached a speed o' 48 mph and coasted for 2.1 seconds t' 138 feet, where t' ejection charge fired. It coasted for another half second for another ten feet where t' parachute opened all t' way at 148 feet. Begad! It descended at 7mph and landed quite close after 14.7 seconds. It looks like this model could fly with a B6-4 even in strong winds. Ya scallywag! T' large body tube size meant that I could pack t' parachute loosely, and I think helped it deploy in t' 40-degree temperature.
