Launcher, motors, glue, sandpaper, sealer and paint not included.

WARP-1 is a basic large high power model rocket. With through the wall fin attach, single 29mm (1.125") motor mount, ready for your parachute. Warp-1 was designed to withstand virtually any motor which will fit a 29mm diameter. Both low thrust, long duration and high thrust, short duration 'stump pullers' are appropriate for this versatile sport rocket. Try F80-8, G60-8. Go HPR with H160-12 or H80-8.

WARP-1.5 is a derivitive of the Warp design philosophy utilizing through the wall fin attach to the 38mm (1.5") motor mount. Try HPR 38mm motors such as H55-12, H110-12, I70-12, J220-12 with nose eject.

WARP-2 is a derivitive of the Warp design philosophy utilizing through the wall fin attach to the 54mm (2.125") motor mount. Try HPR 54mm motors such as I65-8, I140-12, J125-12 or J220-12.

WARP-3 is a large high performance cluster model rocket. Up to three F type motors can be flown as a model rocket. Motor combinations with more propellant weight fall under the HPR class. Try (3) F20-8, F80-12 for a model rocket flight or 3 H80-12 or G30-8 for a high and fast HPR rocket flight.

WARP-4 is a large high performance cluster model rocket. Up to four E type motors can be flown as a model rocket. Motor combinations with more propellant weight fall under the HPR class. Try (4) D12-7, D24-12, E12-8, E25-12 for a model rocket flight or 4 E100-12, F25-12, F50-12, F100-12, G35-12, G70-12, G140-12 for a high and fast HPR rocket flight.

STILETTO is a large scale-like sport rocket with a 66mm host mount! Interchangable motor mounts allow you to prepare several interchange mounts™ in advance of a launch and change them quickly when at the flying field. The kit includes mounts for 3-29mm, 4-24mm, 1-38mm, and 1-29mm. 1-54mm available separately. Stiletto utilizes a reducer section in the middle for increased dynamic stability and a unique five fin configuration for high static stability. The result is a great flying machine. One of U.S. Rockets' favorite rockets! The motor combinations are endless. Try MR G60-4, (3) F20-8, (4) E25-4, or HPR H80-8, H160-8, 3 G30-8, 3 H80-8, G35-8 or 38mm H110-8 or 54mm I65-8 or J125-8.

BERLINETTA is a large fantasy sport rocket with a versitile cluster mount combination. Berlinetta utilizes long transfer tubes to guide ejection gases to the upper section. The wonderfully appealing design is even better on display as the wicked flights are in the air. Extra time is required in assembly to achieve perfection of the shrouded base cone. Try (4) E25-4, D12-3, (3) F20-8, G30-8 or (1) F80-4, G60-4, or HPR H60-8, H80-8.

TOMAHAWK is a scale replica of the famous D-Region Tomahawk sounding rocket. The U.S. Rockets Tomahawk was the largest sport scale kit ever produced when it was first released. It is an excellent display piece as well as a fun and easy flier. The large size and moderate power capability allow Tomahawk to be flown in athletic size fields with E40-4, F80-4, G30-4 or G60-4 motors. Try HPR H80-4.

PISTON STAGER is a U.S. Rockets exclusive design with a piston boosted upper stage. The concept of a piston launcher is to conserve the gases expelled shortly after motor ignition, prior to rocket movement and convert them to mechanical movement. The result is a 300% increase in velocity versus an 'unboosted' rocket. Taken one big step further, the piston system is incorporated into the lower stage of the rocket resulting in amazingly fast upper stage flights and dramatic in flight staging action! Try F80-4 or 3 E25-4 to D12-8. HPR not recommended.

CCV-1 is a very large model rocket using control configured vehicle design techniques. Simple assembly and large size provide dramatic crowd pleasing flights in short order. Try G60-4. HPR H80-4. The central 29mm tube is ejection active and the two external 29mm and two external 24mm motor tubes are for plugged motors. Cover the delay with epoxy.
