Installing your gear and skis well forward of the Center of Gravity - 1" to 2" has improved takeoff and landing performance. Or as
far forward as practical. Remember to maintain COG for your aircraft.
Wire landing gear:
When you receive your skis you will need to make one bend in the torsion bar to align it with your gear wire.
(see pictures at right).
Stock landing gear wire has proven to be the most supple on rough grass fields. The addition of a cross torsion bar between the two legs of the landing gear has added more shock absorption (see pictures at right).
The rear boss on the ski (un-used in the pictures to the right) can be used if you are experiencing problems maintaining attitude of the ski. A second optional torsion bar is installed the same way as the front torsion bar. You will need .040 music wire for the BLGL-9.
The BLGL-12 comes standard with front and rear torsion bars. You will also need to use wheel collars or larger surgical tube and zip ties to secure the additional wire to the main gear wire if you decide to use the rear torsion bar,
otherwise it's a spare.
Using wheel collars or zip ties will make smooth landing more necessary as the surgical tube/ fuel line only installation was built to come apart and save the the ski and torsion bar.
Remember the attitude of the ski is adjusted by moving the sugical tube up and down the main gear wire.
Make sure you have a rigid yet supple installation.
Maintain 4 to 7 Degrees positive attitude of attack of the ski in flight.
Aluminum strut landing gear:
Using a control rod connector mounted on the landing gear strut to receive the torsion bar has proven to be a sound attachment method. (see top picture).
Ground Handling and Flight:
Gun the throttle to begin forward movement and gain momentum - smooth application of power when approaching liftoff speed.
If you are experiencing a difficult time getting un-stuck
from snow or grass you might try teflon spray on the bottom of the ski. Or a paste car wax.
Increasing rudder and elevator throws is recommended.
Rudder use on the ground when taxiing and taking off.
Glide power off on your approach and then use your throttle to gain and desend in altitude.
Practice landing approaces at 50 ft. to determine your aircraft's sink rate and apply what you have learned to your actual approach. Every plane has a different sink rate so best to know when to apply power to stop the sink.
Smooth approach and flare the landing.
Touch down on the heel of the ski.
And remember have a great time and grease those landings!
