Speed system
Mounting the speed system
Most harnesses have two pulleys on each side. Some light harnesses have
simple rings instead. Guide the accelerator ropes (included in the delivery)
from top to bottom through these pulleys. Then fix the speed bar on the bottom
of the ropes.
It is important to adjust the length correctly. If you set it too short, the glider
might fly accelerated all the time, which definitely has to be avoided. If you set
it too long, you might not be able to use the full accelerator travel.
We suggest adjusting the length quite long and then try to estimate the free
travel in flight to shorten it after the flight.
Using the accelerator in flight
The speed system is very effective and smooth running. The glide performance
is very good up to the maximum speed of the MENTOR 3. Please consider, that
the wing behaves more dynamic if a collapse occurs in accelerated flight. You
should be aware, that you might need more height to recover to normal flight!
Attention:
It doesn’t make sense to apply the brakes during accelerated flight. This will
reduce the glide performance considerably, and it will make the wing more
unstable. (Unlike in non accelerated flight!)
To turn, simply shift weight, or push the speed bar asymmetrically. (If you push
the right side further, the wing will perform a left turn.)
You should also use the accelerator for pitch control: If the glider pitches up,
push the speed bar more, if it pitches down, release the speed bar.
Measurements of the speed systems
(publication required by EN 926)
If you use all the available accelerator travel, the A riser will get about 18cm
shorter than the C riser on the MENTOR 3 S and MENTOR 3 M.
