#95223 Video on Android Smart phone

Posted by Captainbob on 26 July 2014 - 06:29 PM

I decided a couple of weeks ago to try shooting some HD videos using the camera on my smartphone, since it is capable of shooting HD 1080p definition with an 8 mpixel camera. Some phones have much more than that now, since my is a Nexus 4 which is almost 2 years old in it's design.  In order to do this, I purchased an inexpensive tripod that would hold the phone, from Amazon for about $17, and a camera clamp mount to hold the phone for another $14 or so. I experimented with this rig this week, and brought it to the field this morning. 

 

The major problem I had was trying to see the screen in the very bright sunlight on the field, even with the brightness set on max. I may bring a towel or something next time, to drape over the phone while I set it in place to capture the area where I intended to fly. This morning, all I could do was to try and have the bottom of the view, on the ground, and get as high as I could by angling the phone up with the tripod. It took me a minute or two, to guestimate where it should be aimed.  I started the camera and took a couple of videos. The hardest thing was trying to figure out where I could fly and not fly out of the range of the camera, but I think I was pretty lucky in figuring this out, because I managed to keep the kite inside the camera view for almost all of the flight. I was concentrating more on positioning the kite more than flying it, so my flying was kind of sedate, but what I was trying to accomplish as fare as staying in view worked pretty well. 

 

This video is of my Rev SLE with magic sticks and race rods which I have been flying for several months.  The wind was around 3-5 mph on the ground at the time I made this video. 

 

 

 

 

The second video is my B series midvent in about 12-14 mph. 

 




#94732 Maintaining inverted hover help

Posted by Captainbob on 27 March 2014 - 03:35 PM

A quad doesn't go left or right, i spins on it's center (clockwise or anti-CW).

 

The correct practice session right now for you is the leading resting on the ground and you back it up.   With enough hours you can do this to the top of the wind window, like it was riding on railroad tracks.  This will take many hundreds or thousands of hours to perfect.  Every kite can go slow downwind to crash (or land softly, it's still just going forward though isn't it?)

 

Please ignore forward drive entirely, work on reverse flight instead, otherwise you are not using the kite to it's full potential.  It is easier to control & predict plus more stable in fight INVERTED.  You don't chase children in a stroller or land on someone's head with the leading edge facing anyway but down!

 

I want to see slow descending control (and then rising it back up again) at the same speed and kite orientation.

 

With reverse control you can fly in any direction, hovering is just your neutral (your naturally resting position), the handles can be balanced on one finger in each hand and the kite is completely rock-solid stationary.  (the location of this balance point is why leaders are used on the flying line-handle point connection)

 

 

Had some good steady wind today, for a change  Eventually,made about 10 climbs to the top of the window, inverted. Started out climbing to about 10 feet, and then gradually increased it. Prior to doing this I adjusted the trim on my Rev B, with alot more down, top leaders all the way out on the last knot.  ani_victory.gif

#94579 New Rev fliers experience

Posted by Captainbob on 10 March 2014 - 05:29 AM

I just got into Kite flying about 2 months ago. Within a couple of weeks, after buying my first foil kite, I joined Kitelife.com and started hearing about the Revolution Kite. Having a background in flying RC helicopters and aircraft, the idea of a kite that was controllable like the Rev, seemed to be just the kind of challenge that I would enjoy. I purchased a 1.5 SLE as my first kite, and started watching all the tutorials by JB, over and over again. When I got the kite, I did the same thing with the DVD. The winds and weather did not cooperate at first, so it was a couple of weeks before I could even attempt to fly the Rev. The first day, that I had some good winds, I was able to launch the Rev, and fly for a couple of hours. I first started working on hovering at high altitude, and then gradually worked my way down. Several hard landings, no crashes, but a couple of dive stops on that first day, gave me alot of confidence that I could actually fly this kite with nobody to show me how except videos and reading. 

 

Within a couple of weeks, I decided I was hooked on Revs, and ordered a mid vent B series and a Race Rod frame, which I just got last week.  In the mean time, I flew the SLE some more and probably had 12 plus hours total flying time. Started working on forward flight, at lower and lower altitudes, slow flight, reverse flight, figure 8's, hovering in different positions of the kite, inverted launches, slides. and spins. The first time I tried a spin, I was really high up and had my fingers crossed, but it was much easier than I thought it would be. Now I am doing 3 spins in either direction in the middle of the wind window. 

 

I flew almost 4 hours yesterday on my new B midvent, and am finally realizing that I am starting to really feel in control of the kite. I don't have to think that much about inputs, it is starting to come naturally. I see the kite do something, and I know how to correct it. Not an expert, but don't feel like a crash or hard landing is around the corner anymore either. I even made some neat tip landings yesterday.  The point of this post is to show that with some organized study, a list of things to practice, some patience,and working on the basics, will have anyone flying one of these kites if they really want to. In the mean time, I learned about equalizing lines, tuning the leaders, modifying the handles with the no-snag mod. using stakes, winding quad lines, etc...... The forum on this site, and on Kitelife.com are invaluable in learning all there is to know about kites in general and the Rev kites. In addition, there is a chat room in the evening on Kitelife.com, when I can always ask a question, and get answers on the spot, from some very knowledgeable kite pilots. All this makes learning easy and fun. 

 

Can't wait to fly my Revs again.    




#94562 New Rev

CB - I agree with 1 exception - if numbers are gonna be used - understate them!! Then instead of pushing a piece of equipment to the breaking point, because it says it's rated to X mph, keep it in a safe operating zone!! 

 

More or less it comes down to two sails are really all that's needed - a standard and a vented - everything else is just filling personal likes in flying styles! Yes there are high and low end (wind wise) options for consideration, how many use them on a regular basis? 

 

With the 2 sails you've got just about everything covered, again everything else is your own preference!

 

Makes it simple enough for me!!

 

 

So it would appear that the performance of a certain Kite and frame combination, would be a bell curve rather than a stated high and  low wind speed, and the ends of the bell curve would be the less desirable conditions to fly that particular model in. I think a bell curve would probably be a better way to illustrate the performance of a kite-frame combination for the beginner. 




#94547 New Rev

The New York Minute Line is like the B-Series line (not Pro), but with an additional venting option. It's my understanding that they use the same leading edge material and sail cloth as the B-Series, so the performance should be very similar, when framed alike and in comparable conditions, especially with the std sail. The green Race frame happens to be a favorite of the pattern's designer, Ben D'Antonio, but any dealer including Revolution will frame it however you like. Order a NYM with a couple frames and it competes directly with the B-Series, IMO.

After 7 years of the B-Series being the only option, it's great to see another pattern on the higher-end Revs!

 

 

This may all be true, but the information on the brochure is very confusing to say the least. It doesn't mention what the wind ranges would be with 3 wrap, or black race frame in any of the 4 sail versions. It does state that it has a 25 panel sail, and a "no fray" leading edge. The info on the Rev site says that the Green race Frames are heavier and stronger than the Black race Rods, so it seems very odd that a single vent kite NYM with the Green Race Frame would have a wind limit of only  3-6 mph. An unvented 1.5 SLE with a Black Race frame ( the weaker one) has a much  wider wind range than that, according to people that fly that combination.  Doesn't make any sense to me. 




#94441 Loose ferrule?

Posted by Captainbob on 11 February 2014 - 07:02 AM

Thanks for the advice Tom.
I followed your steps almost exactly, but used crazy glue in place of the epoxy.

The reason I said epoxy is overkill is I've had to fix a ferrule on almost every center spar I own. I've fixed them all with crazy glue, and after the fix, not one of them has broke loose again. I'm thinking I will change to epoxy though, not because of its adhesive properties, but because I can mix it so it doesn't set instantly. On this recent repair, I dropped the spar, and literally within the 5 seconds that it took me to pick it up, the crazy glue had set into all the little rough areas I had purposefully sanded onto the ferrule/spar. It is glued very well now.

Nail polish remover awaits! Tonight.

 

Not a Rev expert, but many years of RC aircraft building and maintenance. The advantage of epoxy versus super glue, is that epoxy is a bit more flexible when it is dry. Therefore it would resist shocks, bending, etc, where the superglue joint could fracture again. In addition, if you use a good 5 minute epoxy, it will give you plenty of time to properly set the position of what you are gluing. 




#94415 It's Here!

Posted by Captainbob on 06 February 2014 - 06:57 AM

UPS is delivering my Rev SLE this afternoon.  I have been watching the tutorial videos non stop for days, especially JB's tutorials on line equalization, line management, launching, and basic hover . He seems to cover everything.  Can't wait to get it set up and try a launch.
