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 D12-7. The large size and moderate power capability allow
PISTON STAGER to be flown in athletic size fields with F80-4 to D12-7 or
G60-4 to E12-8 motors. PISTON STAGER a superior flyer
on even fairly low power motors!
29mm or 3-24mm
has been successfully tested with as high of power as H90-8 and as high thrust as H120-4. |
Its very strong and lightweight construction makes it fly surprisingly high compared to other rocket kit brands. Test it for yourself! Best flights are with black powder upper motors when flying with F or below
on the booster.
