Flight Log - 2012-12-02 - Rich DeAngelis's X-Ray

T' X-Ray: Nice little payload rocket, usin' a tape-friction-fit motor mount. Nay at all like t' modern Estes X-Ray kit. Aye aye! This has a balsa nosecone, me hearties, transition and fins. Ya scallywag! It is a very light model. This ol' little lass sure made a lot o' flights and she's showin' her age. Ya scallywag! In t' early days this was me tallest and most impressive rocket for t' first year or two, so I would really like t' get her flyin' again and see how high it can go, I imagine close t' 1000 feet. Arrr! T' restore this model, I need t' find a clear BT-50 payload tube since t' old one is cracked.  I don't recall it crackin' durin' a flight, it most likely occurred while in storage.

Recent update: Finally found a clear tube o' t' right diameter: Stole it out o' a new Estes Magician kit a bought for parts.  Expect t' X-Ray t' shine again!

T' X-Ray has now been restored and is flyin' again.  I found t' same clear tube length and diameter from Estes - but I had t' sprin' for a full Magician kit t' get it! I gave it a new Keelhaul®©™ shock cord mount and some new rubber, reinforced t' screw-eye t' t' balsa transition (which t' me suprise was never glued in originally!).  It also received a new 9.3" plastic parachute with longer shroud lines and a good hard cleaning.  Its first new flight with an A8 motor brought it up t' 216 feet at 76 mph (111.5 ft/sec.).  There will be more flights with this for sure.

Flight Date: 2012-12-02
Rocket Name: X-Ray
Kit Name: Estes - X-Ray {Kit} (18) [1965-1985]
Flyer's Name: Rich DeAngelis
Motors: A8-3
Expected Altitude: 200 Feet
Wind Speed: 7.00 mph
Launch Site: Penn Manor School Lancaster PA
Actual Altitude: 231 Feet

This be t' second test flight o' t' just-restored X-Ray, carryin' t' Altimeter 2 in its transparent payload section. 

T' burn be good, lastin' ½ second and acceleratin' this light rocket at 21.2 Gs off t' pad and it produced an overall average o' 7 Gs for t' burn. Arrr! She hit a top speed o' 75 mph and coasted for 2.6 seconds.

At that time, t' ejection charge fired off 4/10 seconds too early, t' rocket was at 217 feet – just a foot higher than t' last flights apogee. This time it kept goin' for another 14 feet before headin' back down at 231 feet.  This flight set a new speed and altitude record for t' X-Ray with t' A8 motor.

T' parachute opened fully, bringin' t' rocket back at 7 mph. Avast! After a 22.7 second flight, matey, it landed in t' grass about 200 feet downwind. Estimatin' that I could get 540 feet with a B6 motor, I had t' scrub t' next test flight because t' winds were too much.
