Depending on the position of the pilot during the flight or the height of
the trike hang points, the R-BUS has the possibility of moving the brake
pulleys to a variety of positions to ensure pilot comfort.
The pulley is fastened to the riser using Velcro and can be adjusted easily.
The riser has 5 possible fixing points (distributed along the entire riser) to
accommodate the pulley.
2 positions for lower hang-points on the higher part of the D-riser,
3 positions for higher hang-points on the lower part of the A-riser.
2.8 USING THE TRIMMERS
The R-BUS does not have a speed-bar, although that does not prevent it
reaching a high cruising speed.
The use of Computational Fluid Dynamics (CFD) in the development of
RSP Reflex System Profile allows us to have the right trimmer settings to
maximise the useful part of the polar curve.
The R-BUS is also equipped with a high efficiency profile, offering
excellent top and cruising speeds.
Neutral position - trimmers closed, all maillons are at the same height.
This is trim speed, better for gliding and less fuel consumption.
Accelerated position- as the trimmer is released, the travel of the C
and D-risers increases progressively and therefore the angle of attack
changes. This way the wing will attain more speed in exchange for more
acceleration, consumption and increased sink.
The R-BUS trimmers have been redesigned and no longer have the
classic metal cleats which made it difficult to make small adjustments to
the trimmers.
This new ergonomic trimmer system allows more progressive adjustment
and the pilot can accurately control the speed at all times.
To put the trimmers in the neutral position, pull the small handle down.
To release the trimmers there are two options: use the handle and pull
down hard to allow the tape to move to the desired position; or pull the
handle up with small movements, allowing the tape to move slowly.
3. THE FIRST FLIGHT
3.1 CHOOSE THE RIGHT LOCATION
For the first flight we recommend going to your usual flying area and that
a qualified instructor is present and supervising the entire procedure.
3.2 PREPARATION
Repeat the procedures detailed in chapter 2 UNPACKING AND
ASSEMBLY to prepare your equipment.
3.3 FLIGHT PLAN
Planning a flight before taking off to avoid possible problems later is
