Nosewheel

• Our nosewheel is free-castoring, so it aligns itself instantly upon ground contact, to help eliminate any tendency to ground-loop. Second, our nosewheel features an ingenious high-viscosity shimmy-dampening system which provides unsurpassed stabilization at all speeds. Third, our nosewheel uses double swing-arm suspension with twin high-impact compression bosses (which are actually an integral component of the shimmy-dampening system) giving SPORT COPTERS unrivaled stability and controllability-even at high speeds and over very rough terrain. In short, our nosewheel system design is amazingly simple and effective…and the only one of its kind.
  
• Steering a SPORT COPTER on the ground with a free-castoring nosewheel. Traditionally, non-steerable nosewheels have displayed rather demanding taxiing characteristics, but in the case of the SPORT COPTER series, steering is easy and smooth. There are three primary reasons for this :
• The high-viscosity anti-shimmy mechanism defeats the "hunting" tendency of a free-castor to amplify or over-steer answers to steering inputs. The viscosity mechanism instantly "brackets" all steering commands.
• Primary steering input is accomplished by independent toe-operated hydraulic disk brakes, integrally mounted with the rudder pedals (all four pedals in the two-place model). These brakes are thoroughly effective and show no propensity to fade.
• It is axiomatic that for any ground vehicle, a properly-designed steering system will seek to center itself in the absence of any other input. The SPORT COPTER accomplishes this by a simple spring-loaded centering device which effectively maintains whatever steering input has already been "bracketed" by the viscous damper.
  
• The net result is not only authoritative steering, but an aircraft that practically "nails" itself to the runway centerline during take-offs and landings.

Rotorhead

• All rotorhead components have built-in, replaceable bumperstops (made of a new broad-temperature polymer) which protect all moving parts from each other as they reach the limits of their respective movement-arcs. The components of other rotorheads simply mash into one another when they reach their arc-limits, leaving dents, scoring and an occasional crack.
  
• The rotorhead itself is actually shock-isolated from the aircraft by a compression-type shock-mount for the roll axis pivot. This isolation is achieved within the longitudinal carry-through by means of specially-formed polymer and Teflon bushings, compressed and mounted with machined stainless steel retainers, caps and bolts. This results in a significant reduction in shock and vibration transfer between the rotor and the rest of the aircraft. In the upper portion, between the tower plates is a replaceable polymer stop to prevent damage to your hub if your blades should experience flap. Both the bumper/limit-stops and the rotorhead isolation are intelligently engineered features found in no other gyrocopters, but in time they will almost certainly become accepted design standards throughout the industry.
  
• The heavy-duty upper rotorhead has double-bearing stack and taller towers for the proper undersling for heavier loads and a stabilizer bushing to prevent side-load flexing of the tower plates.
