The ULTIMATE extreme performance helical piston made of a 50% stronger polycarbonate resin, with embedded steel teeth specifically designed to work with Extreme torque up helical gears (ref#17164) to give a extreme heavy tuning of 170-190 m/s.?All dimensions of the piston has been reworked to fit perfectly inside ULTIMATE gearboxes and gives a smooth low friction performance.?The length has been adjusted to make a perfectly even contact between the first gear and the first teeth of the piston preventing breakage and minimizing wear.??With ULTIMATE Extreme performance helical piston you get: • Increased strength. • Increased durability. • Low friction. • Perfect fit in ULTIMATE gearbox. • Perfect combinations of polycarbonate teeth and steel for impact-energy absorption and strength. • Optimal angel for first-contact between piston and gear. • 50% stronger polycarbonate (then ULTIMATE high performance piston) • Reduced stress on motor. ?In extreme tuneups for power, the forces acting on the piston and gears are huge.?Every little detail in design and size of the components are very important.?When the gear makes first contact with the piston, it slams with great force against the first section of teeth on the piston.?ULTIMATE pistons have been designed with polycarbonate teeth for the first section, to allow it to absorb impact fare better than steel.?As the piston travels further back, the pressure on the teeth increases dramatically, this is where steel teeth gives maximum strength against breakage.??Most be used with appropriate ULTIMATE® upgraded internal components to secure the best performance and durability.??For use with classic Army gearboxes modifications are required.
This piston is comprised of new materials never before used combined with innovative processes. The Madbull PX piston is designed with full metal teeth and hardened polymer. The metal teeth is produced with MIM (Metal Injection Molding), which gives the teeth a degree of flexibility without breaking.? ? Features: • State of the art composition • MIM full metal teeth • Alien green polymer 14 teeth (one tooth removed to reduce stress on gears)
Madbull PX piston er designet med full-metall tenner og herdet nylon fiber. Metalltennene er produsert med MIM (Metal Injection Molding), hvilket gir tennene en viss fleksibilitet uten at de knekker.
