The Roadster 3 is well damped in roll but under certain circumstances it is possible for the
pilot to induce oscillations. This is caused by a combination of the engine/propeller torque
and pilot weight shift and/or brake inputs. To stop oscillations it is best to reduce the power
slightly and ensure that you remain static with weight shift and brake inputs. Once settled
you can once again apply full power. Under full power the torque effect will attempt to gently
turn the wing, using weight shift or adjusting the trims asymmetrically is the best method to
correct this.
Normal Flight
Once at a safe height you can release the trimmers for a faster cruise speed. If your motor has
enough power, the Roadster 3 will achieve very good straight line speeds whilst maintaining
level flight with trims fully released and full speed bar applied. Be cautious when releasing the
trimmers beyond the red line, only do so in calm conditions.
For better penetration in headwinds and improved glide performance in sinking air, crosswinds
or headwinds, you should fly faster than trim speed by using the accelerator system, or the
trimmers. In turbulent air the reflex profile is very stable. It will resist reasonable levels of
turbulence with a high resistance to collapse without active pilot input. The faster the wing is
flown the more inherent stability there is, as the reflex has a greater effect. In mild turbulence
it may be best to not attempt to fly the wing actively and let the profile absorb the turbulence
itself, indeed application of the brakes whilst accelerated will reduce the inherent stability of
the profile. However in very strong turbulence Ozone recommends to return the trimmers to
the fully slow position and fly the glider actively. This way, you will be in the best position to
react correctly should a collapse occur.
For maximum efficiency whilst flying downwind, release the speed bar and return the trimmers
to the slow position. By pulling the trimmers to the slow position and applying a small amount
of brake, the Roadster 3 will achieve its best minimum-sink rate; this is the speed to use for
thermalling and ridge soaring whilst free flying.
IMPORTANT
Never apply the brakes
whilst using the speed
system - it makes
the wing more prone
to collapse. During
accelerated flight use
the TST for directional
control.
