SPEED SYSTEM 

Certain Trike manufacturers give the option to use a speed-system acting on the front of the risers to accelerate the wing, which may be 
used in conjunction with the trim system. We have designed the F3Bi risers with this in mind. 

ASSEMBLY & ADJUSTMENT 

Before the first flight, it is imperative to make sure that the speed system will not be applied due to being adjusted too short. 
We recommend following the trike manufacturer’s instructions for adjustment.

RISERS 

 
The F3Bi is supplied with risers featuring a split A riser. The 1st A-
riser attaches to the central two A lines (A1 & A3). The second A-
riser is attached to the outermost A line (A5). At no time should the 
pilot change the risers or use risers not intended for this specific 
glider as this will affect the performance and safety of the glider. 
The riser is equipped with both an accelerator and trimmers. 
 
 
 
 
 
 
 
 
 
 

WARNING: 

The use of the speed system in turbulent conditions or close to the ground is dangerous. While flying with the 
accelerator, the wing has a reduced angle of attack and is therefore more susceptible to turbulence and may 
collapse or partially deflate. Gliders react faster when accelerated and may turn more. The accelerator should 
immediately be released in this case.
