Slide Creek Landing.
Landing in Slide Creek, Alaska. Southern Alaska Range Foothills. Unfortunately my camera whited out the horizon.

Hey Garrett, I think you need to remove the "s" in https for the site to accept it.
fixed. Thanks.
that is really cool. can you give a lat/long for the airstrip?
yes great video garrett looks like you might have to watch for doll sheep on that runway.
Awesome video and landing spot and great piloting skills. That looks like a Gibbo Mako 15 wing, can you share your experiences with this wing...in term of flight characteristics, I would like to know the pros and cons of this wing...can you enlighten us with your opinions? Regards, Rizzy
Thanks all! Coordinates are 64.02320, -147.31865.
Yes Rizzy it is a Mako 15.
Strengths:
speed
It is ok in turbulence but a streak is better (I have been borrowing a friends streak 2b lately).
Easy to land.
Weaknesses:
Power off glide
Sink Rate
Take off distance
Climb rate
Takes a lot of rpm's for level flight
RPM in level flight 5600-5800 1 up with 582 (I fly at low density altitudes) 2 up 5900-6200.
Sink Rate power off at trim 1200/minute
trim level flight 55-60kts
Mark Gibson is sending me a trimmer block that might help.
More pros:
Responsive in lower speed ranges.
It handles well too.
The one I flew had a pitch block and flew faster than that.
cburge did the one you flew drop out of the sky like a brick when you cut the power?
What were your rpm's in level flight? What machine was it on?
I’ve flown most of Gibbo’s wings and have owned three. I've commented several times before about how they need to be flown a little differently to extract performance out of them.
Their low aspect ratio requires more push-out to get the whole wing (tips) working. If you pull in excessively during turns, climbs and power off decents (like most trike pilots) you will only have the nose working (predominantly).
Dive-ability is something that some (but not all) of us trike pilots like. A low aspect ratio wing has substantial dive-ability. Only the nose is creating much lift and the tips, due to twist/washout/tip area aren’t doing much due to their comparatively low Angle-of-Attack (AOA).
If you pull in…it will dive…but will remain yaw stable at all speeds. Some people love this feature and others don’t. The Manta 12.5 was even more noticeable...and some guys absolutely love it. Sounds like you don’t. Nothing wrong with that. We all have our own flying quality preferences.
If you are going to fly a Gibbo wing you need to explore the lower speed end of the envelope if you want the whole wing creating lift and fly more efficiently.
When you need best glide, best climb, reduced fuel burn you’ll need to get the tips working. If not…enjoy the dive-ability…and overall sportiness of it.
Thanks cburg, I noticed that when flying it. I don't pull in during turns, climb out, or dives. I coordinate my turns, used to climb out with the bar neutral but with this Mako I have to push it out or it descends a bit at full power (yes I tried changing trim position). I used to pull in my wizzard on landing approach for excess airspeed like a gang glider, but the gibbo wing will come down at a 2:1 if I do that. That said, pushing the bar out all the time gets annoying and my power off sink rate with bar out is still 1200-1000fpm and a max 4:1 glide. I am waiting on pitch block, hopefully that will at least make keeping the bar out all the time easier. If not I will likely trade/sell the wing. It doesn't PIO at all, but neither will a streak if you stay ahead of it.
Be careful with the pitch block until you get used to it. It will be a different wing with much more pitch authority. You may or may not like it. I doubt it will resolve the areas you have an issue with. Sounds like you like more of a floater (larger and/or higher aspect ratio).
These typically have improved performance, but lack yaw stability throughout their speed range (tip walking). I really do not like this, but some guys love flying these what I call "one speed wings" that are only happy at one speed (my Stranger was an example).
I like being able to dive wings and have good directional stability at all speeds...but also enjoy "one speed" floaters too...I have a 29 meter floater.
Did you try the pitch block yet?
I was thinking that you should get an hour in a helicopter doing autorotations. It sounds goofy, but I promise that you will feel much more comfortable in your trike than you do now. In an auto you would swear you are going straight down, but you aren't. Especially in a 300. R22s glide pretty well (but will also seem very steep to you). It will completely change your frame of reference and allow for a new sight picture. I really do recommend it.
When you get back in your trike you will feel like you are flying a sailplane.
What is a pitch block? Any pictures?

Hello Gang
For quite sometime pilots have been asking me when I was going to come up with a trim system for my Wings....My standard answer was my Wings don't need it....The real reason was I hadn't come up with a system that I thought would actually work and was more then just a marketing gimmick.....For the past 35 or so years we've been attaching our Wings the same basic way....the hang block is fixed to the keel and the Trike attaches and pivots below the keel of the Wing.....This works fine....."BUT".....it puts you at a mechanical disadvantage (leverage) when its comes to pitch authority.....You are basically pulling the nose down from 5" below the keel....Can you imagine how much easier it would be if you could use the weight of your Trike to your advantage and move the pivot point above the keel ( 7" above the standard pivot point)?....Well I could imagine it and I decided I needed to do it....I designed and built the proto system over the past couple of weeks and couldn't wait to fly it.....a few of my flying buddies knew of it and were excited too....I knew it was going to work but had to prove it....the holidays and weather kept me from test flying it.....Finally yesterday was perfect and myself and Steve Burns were able to fly it.....WOW.....GibboGear has a pitch system that works!!! What it does is vastly reduce the pitch pressure when you have the bar pulled in past that comfortable cruise position....instead of using your arm strength you use the weight of the Trike to hold down the nose....it's different then just moving the CG forward because when you move the CG forward you change how the Wing behaves, all the GibboGear device does is swing the weight from a more advantageous place thus reducing pitch pressure but not changing how the Wing behaves.....Other advantages beside reduced pitch pressure is improved roll and a smoother flare feeling when landing....Tugging with a Trike and my device will be so much easier too....Check out the pictures....Happy New Year....Gibbo
Can't see the picture without joining the yahoogroup. Can you cut and past it at alltrikes?
