Blown Fuse

Written by

If you were having a hard time deciding what day to come out to HellFire the decision was just made for you…This is the biggest single motor launch HellFire has had. Blown Fuse will be flying on Thursday, July 31st 2008 during the Tripoli Research Launch portion of HellFire. 

Blown Fuse is built and flown by Ron Weigel, Jerry Hughes and  Jack Blair. The rocket has flown before, the first flight was at Balls 15 where it reached an altitude of 17, 200 feet AGL and again at Balls 16 where it reached an altitude of 15,200 feet AGL.

Blown Fuse is a 10" fiberglass filament wound airframe with 1/2" Baltic birch fins that have a fiberglass overlay. The complete rocket is just about 16’ tall and weighs in at about 90 lbs without a motor. With the motor installed the rocket weighs in at just around 200 lbs.


The rocket will fly on an EX motor which was also mixed and cast  by Jerry, Ron, and Jack that equates to a P7000 and utilizes the Wimpy Red propellant formulation.


Recovery of the Blown Fuse will be dual deployment configuration. Deployment will be controlled by a pair of Olsen altimeters (Go Olsen or Go Home!)  With a Rocketman 8ft ballistic drogue chute stuffed into a Rocket Rage deployment bag. The Main parachute will be a Rocket Rage RRQS210 also stuffed into a Rocket Rage Deployment bag.

Jack has been a HellFire Hellion since about 1998 and a rocketeer even longer than that. When he moved away to Washington we'd see him for HellFire most years anyway. It seems the salt is in his blood. In May of 2004 Jack succesfully flew his Level 3 project "Rumble Bee" up in Bellevue, Washington. Now, Jack's back in Utah and he has a whole lotta rocket to show us...

This rocket is called Homer and it is  5.5 inches in diameter. Homer stands at 9 feet 10 inches long and weighs in at a spry 28.5 pounds fully loaded. Homer will be flying on an M1315 motor. Homer's  first flight will be at Hellfire 13 on the Bonneville Salt Flats, Saturday, August 2, 2008.  The projected altitude for this craft is right around 9,000 feet AGL. 

Should be a spectacular flight!

Nike Smoke

Written by

nikelogo David Spencer's beautful Polecat brand Nike Smoke is making its way back out to the salt this year. It is 10" in diameter and measures up at 11' 8" tall.

The rocket boasts a 98 mm motor mount (2/3 scale). The big Nike Smoke weighs in at about 51 lbs loaded. Deployment is done by a BlackSky AltAcc2 and a MissileWorks RRC2. He is planning to launch it again at Hellfire with an Aerotech M1419. According to David, the other Nikes will also probably fly at Hellfire, and will be on display with the big one.

The 5.5" dia  54 mm (1/3 scale) is another Polecat Aerospace kit, he has flown it about a dozen times on motors ranging from an I284 to an AMW K670GG. David will probably fly it on a K550WL or K670GG with an expected altitude around 6000'. 

The two small Nikes: a Quest kit 1.4" dia. 18mm (1/12 scale), and the tiny one is a scratch-built 0.3" dia. (1/55 scale) micromaxx with altitudes reaching a whopping 150' or so.  David certified level 3 with it at LDRS 26 on an M1297 Aerotech motor.

Little V2

Written by

ImageThis is the original Overmoe V2. They call it the "Little V2" but there's nothing little about it. Based on an original Hott Rockets kit, this V2 is 9.25" in diameter and weighs in at 65 lbs when loaded!

This craft flies on an M1419 and hits about 7000 ft each time. This V2 Has flown about 9 times all on the M1419 motor. Brad did his level 3 on this rocket. Even after all of these flights it still has only a few scratches on it for damage.

Jerry Hughes - Aces High !

Written by

Here is Aces High, it's 7.5 inches in diameter and as you can see, big. The motor is sitting to the side of the rocket in this picture. the Motor's designation is an "O" 10,000 with a blue flame. I think that might be a little agressive of a designation but BurnSim is what we are trusting here.{vsig}jerryhughesaceshigh{/vsig}

This is an Experimental motor so the rocket will be flown during the Tripoli Research Launch portion of HellFire on Friday. It's simulations show it hitting around 16,000ft at apogee.


Aces High suffered a motor failure on the pad at Hellfire 17. The rocket was a complete loss.

Tim Thomas is Thunderstruck

Written by

thunderstruckI will be launching my Talon 6 "Thunderstruck". I will power it up with a M2400 Blue Thunder. This should be the rockets 4th flight. I am flying it at Chile Blaster on the 28th. on a L2375 White Thunder. The Hellfire flight should be around 12,000ft.

Thunderstruck is 12'-8" tall and around 50lb. at liftoff. The rocket is all glass, with Fly-lite fins and has a 98mm mount. She has extensive graphics by Mark @ Stickershock. There is a video @ YouTube--' Tim Thomas Level 3' The Talons are beautiful rockets, and so far Thunderstruck has been a great flier.

Fast and sleek, the Aero M2400 should put on a fine show!

Here's some shots of the rocket the Overmoes (Alan and Brad) plan on flying at HellFire15. I showed it at the last meeting. We are planning on putting it up on an N1000 which is the long burn N which has a 12 second burn. The rocket is about 10 ft tall and 5" in diameter. We are calling this project Sgt. Pepper.  It should be cool one way or another.

Bruce Bell's Doberman

Written by

I have always built short fat rockets because I liked seeing them take off slow. So for Hellfire this year I decided to go in the opposite direction and build long and lean. My project started with a Liberty Launch Systems Competitor 4. This is a 10 foot long all fiberglass kit with G-10 fiberglass fins, coupler and a 5:1 nose cone, and comes equipped with a 24" long 75mm motor mount tube and centering rings. The booster section is only 48" long, which could present some problems with a few motors that I might want to use and not provide enough room for a proper installation of a drogue system. So I also purchased an additional coupler and 24" airframe section. With the additional section added on, the booster is now 72" long, plenty long enough for even the longest 75mm motors.  

I started with the motor mount by gluing the forward CR on to the motor tube about 2" from the end. I drill a ¼" hole in the forward CR and feed the Kevlar shock cord through the hole and tie it around the motor tube. I fill in with generous amounts of epoxy to hold in place. I drilled 2 small holes in the other centering ring (CR) and mounted (temporarily) a pair of small screw eyes.
This way I can slide that CR on and off while gluing the fins in place and gluing the motor mount tube in place. Once the 3 fins are glued in place, I pull the rear CR off and now apply the fillets to the fin roots. Once that is done, I glue the rear CR on, leaving enough MMT tube to glue on the SlimLine motor retainer. I cut about ½" off the base of the nose cone and use this ring to reinforce the tail of the rocket by gluing it in behind the rear CR. This helps with those hard landings out on the Salt Flats. I now apply some nice fillets to the fins on the outside using some thinned JB-Weld.
The Liberty kits do not come with an electronics bay, but they do come with a coupler and end caps. I purchase the hardware including ¼" threaded rods, nuts, nylon locking nuts, washers, wire, terminal strips and a 9v battery holder. The altimeter of choice for me is the PerfectFlite ALT-WD. I start by gluing the end plates together after dry fitting them in the coupler tube. I marked where the threaded rod holes and the U-bolt holes need to go and drill those.
I then cut the 2 threaded rods to about 3" longer than the coupler. I mounted the hardware in the mains side first including the threaded rods and the U-bolts. Note, I used nylon locking nuts to make sure nothing falls off at a time when you most need things to stay together, like just before your chute deploys.
I mounted the drogue side end plate to the threaded rods as shown below. I cut out a piece of 1/8" plywood so that it fits comfortably inside the bay and marked along both sides of the threaded rods with a pencil on the plywood. Then I glued on some heavy ¼" I.D. tubing for the sled to slide on the rods.
I then very securely mounted the 9v battery holder and the altimeter on to the sled, on opposite sides. If there is a crash, the battery would normally be a projectile, so this keeps the battery away from the altimeter.
Now with the electronics mounted, I glued on the charge cups and the terminal strips. I used #20 gauge strip wire, and went ahead and wired everything up, leaving a generous loop of wire inside the bay to allow accessing the bay for battery replacement. I used a on/off switch from Aerocon to turn on the electronics from the outside. I notched the bottom of the mains compartment to accommodate this switch.
I painted the whole thing with a coat of "glass-friendly primer" and a coat of black enamel. I then added a pair of PML rail guides. I plan on flying the Doberman on a Aerotech M-1297 at Hellfire, will weigh 25 pounds and fly to about 8,000 feet.

Gemini Titan

Written by

Bob Morstadt's HellFire project this year is a beautiful, scratch built Gemini-Titan. Bob's Titan is a 5-inch diameter model that uses 2 extra long H-motors (Aerotech H268-M). The highly detailed capsule is made from the Revell plastic model.  Bob is utilizing a Q-Burst relay system.  The forward propellant grains are painted with Quick-Burst pyrogen. The Gemini has clear plastic fins, rail buttons, a ten-foot diameter parachute with piston ejection, and weighs about 10 pounds.

Von Braun

Written by

vonbraun3Steve Anderson is planning on staying busy at HellFire this year, he has lots of big projects. His biggest has been named "Werner von Braun" in honor of the Chief V-2 Scientist. The rocket is a PoleCat Aerospace kit and weighs in at 11 pounds empty and could weigh nearly 20 pounds with motor, recovery and electronics. Steve is planning on using dual electronics with PRM to support dual deployment. He's considering his Rocketman R7 parachute but is not sure if it will be big enough.

His engine choices at this time are the J570, K185 and K700.  He hasn't settled on which one quite yet but he does have the K motors ready to go.
