RISERS
The risers feature coloured long range Rollercam trimmers; stronger brake handle magnets; TST steering
system; fully adjustable brake pulley height settings and coloured risers for easy identification. See pg 30.
Trimmers
The Roadster 4 comes equipped with a new trimmer system featuring Roller Cam buckles and printed
webbing. This system allows for easy adjustment of the trimmer position and prevents the trimmer
buckle from slipping. The coloured webbing includes a black and white line with an arrow to indicate the
recommended trimmer position for takeoff. Additional marked lines on the webbing assist with symmetrical
trim adjustments. The Roadster 4 has been flight tested to EN 926-2 standard (flight test) with the trimmer
fully pulled to its slowest position.
The wing inflates well in the slow (standard) setting but the trimmers can be released, up to the white
arrow for faster inflation behaviour during the take-off, this is especially useful in light winds and/or at high
altitudes. The white arrow position is a good setting for 'normal' powered flight, it allows you to cruise
around with a relatively high trim speed whilst retaining efficiency. The lines on the trimmers indicate a
reference for symmetry.
The standard (slow) trim setting is ideal for climbing under power, whilst thermalling, free flying and when
flying in turbulent conditions, brake pressure is at its lightest and the handling at its best.
To increase cruise speed you can use the accelerator system, release the trimmers, or do both. Using the
speed system has exactly the same effect as releasing the trimmers. Unlike some other PPG wings, it is
safe and possible to fly with the trimmers in the standard (slow) position whilst using the full range of the
foot operated speed system.
With the trimmers fully released it is possible to use the brakes for directional control. However when flying
faster by accelerating further with the speed system directional control should be maintained with the TST.
Using the brakes at speeds faster than the trimmer-released position can lead to a collapse.
