The Montana/Frenzy style kites are depowerable systems that are designed to be used in a harness. Flying these kites without hooking in can be
difficult and cause some strange behavior in the kites.
A little bit of understanding on the kites:
The bar slides along the chicken line of the kite. This changes the profile of the kite and will increase power as the bar is slid towards your body
and decrease power as the bar slides away from your body. This is different than simple angle of attack (AoA) on a fixed bridle kite. When you slide
the bar in, it pulls on both the trailing edge of the kite as well as the B & C risers (center bridle attachment points). This changes the
airfoil shape of the kite dynamically as you sheet in and out on the bar. Oversheeting the bar in (close to you) will cause the kite to flare and you
will lose power and the kite will begin to reverse and drop, this is similar to pulling in the brake lines on a fixed bridle foil. Undersheeting the
bar (furthest away from you) causes the kite to "flag out" and lose its shape which will dump the wind out of the kite and lose power. Think of this
like holding a bed sheet in the wind and letting it flap. By controlling the amount of sheet in and out on the bar, you can find the sweet spot of
the kite where it will be powered up properly for you to fly. This ability of the kite to completely sheet out or oversheet in is the reason the
Montana/Frenzy kites have such a huge wind range. It is also the reason they do not produce quite the same power output as a fixed bridled foil of
the same size. By depowering the kite fully, you are able to take a larger kite out in winds that would normally be way overpowering. Nice thing
about this is that when you do power up the kite you get to experience the full size of the kite and big air's are very possible. Think of it like
taking a 7 meter blade out in 20-25 mph winds but the ability to automatically size it down to a 3 meter when you want to.
Ok, now on to the depower strap:
The depower strap is the adjustment that is located on the front flying lines that are hooked into the center of the bar. The adjustment strap is
usually located right above the chicken loop line and starts where the sheeting of the bar ends. This adjustment changes the angle of attack of the
kite just like pulling in the brake lines on a fixed bridled foil. Pulling the power adjustment completely in (so it is at its closest or shortest
adjustment point) will pull the leading edge of the kite forward and depower the kite at its maximum amount. Now when you sheet in the bar, you
should not be able to get full power out of the kite and oversheeting will be very difficult to do. Letting the power adjustment completely out
(furthest or longest setting) will fully power up the kite and oversheeting will be possible but depower will be limited. Usually the power
adjustment strap is pre-set for the current wind conditions and power is controlled through sliding the bar. If you find that you dont have enough
power when you sheet in you can power up the kite more with the power adjustment strap. If too much power, depower the kite the same way.
Ok, to put it all together:
Normally, it is poor safety habits to hook into a harness on a fixed bridled kite. I always suggest learning to fly the kite fully before hooking
into it. BUT-with the release of new depowerable kite systems such as the Montana & Frenzy (and others that are popping up on the market),
hooking into the kite is part of the overall design and you lose a lot of the control and safety of the kite by not hooking into a harness. Without
hooking in, you can not depower the kite like it is designed. You will also have a very difficult time getting the kite to fly properly and turning
will be very difficult to do as well. Launching the kite without the depower means that you might be launching the kite fully powered which can be
very dangerous.
Wether you are hooked in or not, always depower the kite before launching by pulling the depower strap in to its shortest point. Once the kite is in
the air then you can adjust the powerstrap to fit the conditions. Pulling in the leading edge of the kite will also help it launch and fully inflate
the quickest. If you want to fly without hooking in at all then you may find that the best way is to fully depower the kite and then pull the center
line in about 2-3 inches and hold it with one of your hands. The amount of chicken line you pull in will vary depending on the conditions. You may
still need to give the center lines a good tug to get the kite to launch but it should be flyable. You will only want to do this in the lighter winds
and I still recomend hooking in to get the full safety and control from these types of kites.
Most of all, do NOT be afraid to use the safety releases. The cost of an emergency room visit will be tons more than the cost of several sizes of
kites....and a lot less painful!
Kite safe, practice in light winds first then move up from there.
Hope this information helps!
