HellBoy 70 Goes Big - 70 motors loaded in 2 stages   flight 8 video:   11/17/12   CMASS   Amesbury, MA   
First stage 51x C11-0 engines - all 51x motors fired (= BP I560)
     Rocketry Forum thread     playlist of all HellBoy videos
Second stage 19x C11-0 engines - 18x motors fired (= BP H200)

HellBoy 70 lifted off fast and straight on a quiet rush of fire and smoke, transitioning quickly from first to second stage.

All 51x C11 motors in the first stage fired creating a column of yellow flame and white smoke,
sending up the rocket up quickly reaching a peak acceleration of 16.9 Gs.

Second stage fired one second later, in a smooth quick transition,
firing 18 of 19 loaded C11 engines and reaching a peak velocity of 272 fps (185 MPH).

First stage fell 20 ft from the pad, and the interstage coupler is in good enough condition to be re-used. Sustainer hit apogee at 1250 ft and the chutes deployed for a clean recovery less than 200 ft from the pad.

Data from the Featherweight Raven is fun to have, and its advanced programming capabilities were essential to the success of this flight,
firing the second stage and both ejection charges. This chart of acceleration, velocity and altitude data from the Raven shows in the (red) acceleration data, strong thrust of the 51x C11 engines in the first stage, a spike as the stages separate, and then the thrust curve for the 18x C11s fired in the sustainer.

The flight went very well, firing 69 of 70 loaded motors. I believe the one motor that did not fire in the sustainer was due to that flashpan being prepared more than two weeks earlier, for the previous flight in which the second stage was not ignited. That makes 213 motors fired of 214 hit by flashpans in 8 HellBoy flights.

Thank you very much Bill Spadafora for:
1) helping with setup at the pad
2) being the safety man on the RC emergency deploy charge
3) emailing me a great video clip from the pad which is edited in with the other videos
4) running a great rocketry club, CMASS, for another great season!

HellBoy 50 - 50 motors loaded in 2 stages   flight 7 video:   11/3/12   CMASS   Amesbury, MA     Rocketry Forum thread   
First stage 31x engines: 19x D11-P and 12x C11-0 - all 31x motors fired (= BP I340)
    playlist of all HellBoy videos
Second stage 19x C11-0 engines - no motors fired because Raven altimeter determined velocity too low

The first stage flashpan fired all 31 engines in the booster in a big cloud of smoke and a trail of flames.

The rocket weathercocked severely due to the windy conditions and being overstable, becoming more horizontal than vertical at about the time the second stage was due to fire. Because of the safety conditions set for the Raven, the second stage did not fire.

As the rocket continued to arc over and started to drop while traveling horizontally, both the drogue and main were deployed by the Raven at about 400ft altitude. The first stage was dramatic and the flight was safe.

As a planned precaution, Bill Spadafora used the RC control to fire the safety ejection charge after the chutes deployed to clear that charge before the rocket touched down.

Unfortunately, due to the speed the rocket was traveling when the chutes deployed, the onboard video camera (Boostervision HD Gearcam) was separated from the rocket. It had been taped to the rocket very near where the Kevlar recovery harness caused a slight zipper in the HellBoy. Thanks to Bill, Ken and several other folks who were kind enough to help look for the video camera. Despite looking for the camera for over an hour, it was not found.

flight 3 video:  Pro-X 54mm 4grain K740 C-Star   10/6/12   CMASS / MMMS   Berwick, ME  
It pleased me greatly to fly the same propellant formula as used on the Space Shuttle.
Lifted off loudly on a hard thrusting bright white flame and column of white smoke.
Apogee at 1360ft. Dual altimeters plus motor backup for this single deployment flight.

Spinning Saucer of the Apocalypse     Rocketry Forum thread     playlist of all SSoA videos
Original design, 10 motor clustered, spinning saucer, modified upscale of the Turbine Rocket Saucer. 3ft diameter 7lbs flight weight. 
Flights create lots of flame and smoke while spinning at almost 1000rpm. Flight is for effect, and altitude stays under 100ft.
Typical motor configuration is 2x G engines in the center firing straight down for lift
and 8x D engines mounted horizontally on top of the outer ring to generate spin.
Built early 2012. Flown 7 times in 2012 firing all 70 motors loaded.

First 2 flights video:   4/28/12   CMASS / MMMS   Berwick, ME      

First flight: trial run for an experimental project, used 2x F40 motors for lift and 8x C11 for spin.
Only went up about 40ft but stayed flat throughout flight. Confirmed that doubling lift and spin power was both safe and necessary.

Second flight: 2x G64 for lift and 8x D12 for spin. Got more lift, getting closer to 100ft,
but a strong gust of wind caused the saucer to land on edge requiring minor repairs.

flights 3 and 4: both flown on 2x G64 + 8x D12 at LDRS XXXI on 7/14/12

flight 5: 2x G64 + 8x D12   7/21/12   CMASS   Amesbury, MA  
 This video gets a good close up of the fast spinning recovery.

flight 6: 2x G64 + 8x D11-P 10/6/12   CMASS / MMMS   Berwick, ME

11/17/12   CMASS   Amesbury, MA    
flight 7 video:  used 2x AT G80T engines for lift instead of the usual G64W, resulting in a slightly quicker
and higher lift and more definition to the helix of smoke created by the 8x D11-P motors used for spin.

FlisKits 10th anniversary   launch video   10/20/12   CMASS   Amesbury, MA
Jim Flis and FlisKits always make sure lots of fun is had at their annual anniversary launch.
Fliskits provides delicious cake, pays for the field and sets up fun events like a 8x way Frick-n-Frack drag race and
their amazing styrofoam cup UFFO rocket specially with streamers.

English Electric Thunderbird     2011 flights     Rocketry Forum thread     playlist of all Thunderbird videos
2012 flights video     Flown twice in 2012, firing all 22 motors loaded.
Both flights on 1x F30 + 6x E9-6 + 4x D11-P, a great motor combination for this rocket,
a nice long burn pushing the rocket up 500 to 800 feet.  

The English Electric Thunderbird is a very cool looking surface to air missile deployed by the British from 1959 to 1977.
It has four drop off boosters with canted nose cones and engine nozzles.
This is a 3/20x scale model of the actual missile and a 2x upscale the FlisKits kit.
As built: 11x motor cluster of 24mm engines, 42.5 inches tall, 7.5 lbs flight weight.

 Demon Star     Rocketry Forum thread
Modified version of the R and R Model Aircraft Delta Star rocket glider.

As built 2.3lbs flight weight, 36" long, 30" wingspan.
Flown 3 times and destroyed.

   First 2 flights:   1/14/12   CMASS   Acton, MA
Lifted off fast on G64 engines. Windy conditions made glide control challenging.

Third and last flight of the Demon Star:   6/10/12   CMASS   Sudbury, MA
A gust of wind pushed the glider over on its back as it lifted off fast on a G64. I pulled up one second on the controls before
 realizing it was  inverted and pushing down, but too late. Glider met nearby trees at about 100mph and was destroyed.
