Tired of pump me up

Postby THE POWER » Thu Dec 03, 2009 9:24 pm

I cannot believe that all these years later pump me up is whinging on about foil kites!
I really enjoyed the initial arguments and how hot under the colar people used to get. PMU used to have some fairly sarcastic points.

But NOw?? Three years later when the market place has changed to offer people such a variety of tube kites perfect from beginner to pro. Its not like it was when there were only c kites and foils and people could be convinced away from tube kites into trying an alternative. Why does he still hanker on about areodynamic inferiority. People aren't duped easily. I thought PMU was a young
guy but he must be some old bore with ADHD or something or Aspbergers (sorry to anyone with Aspbergers)

Can't PMU please go someplace els and annoy another group of people maybe like a dogging site or something??

Oh come on,
I thought you 2 were girlfriends,
but that was a long time ago....
haven't seen a sign of PMU in ages
-not on "ignore" but I don't search for it either.
Troll much?

You have to kind of feel sorry for the guy.

My 11 year old son has a kid on his soccer team just like PMU. Not many friends, kind of stays to himself over in the corner, and does not have very good social skills. He compensates for his lack of social skills by lashing out and attacking the other kids verbally and some times physically in an attempt to make himself look cool and tough to everyone.

No one really cares about what he says and no one takes any of his arguments seriously. He is basically a legend in his own mind.

In a crazy sort of way he is actually helping FS out. His constant rants keep the FS brand in the spotlight on this forum and expose more people to the FS brand each time he tries to tear them down. So he is actually doing the opposite of what he is trying to do.

I say he is harmless.

Inflatables are vastly superior to ram airs. I've summarised the reasons for the superiority of inflatables:

- Rams have a HUGE drag ("D") coefficient compared to inflatables, making them more inefficient. This is reflected in their poorer lift and inability to fly as close to the window's edge as inflatables. Large rams can pull steadily enough, but lack the aerodynamic finesse of good quality inflatables.

- Because large ram airs contain a much larger mass of air compared to inflatables within their pockets, inertia is HUGE. Large ram air kites contain OVER 11kg of air in their cells vs 2-3 kg for inflatables. It is very difficult to move this mass of air across the sky. This causes a multitude of problems including poor lift, slow turning, slow sining, and difficulty kitelooping. Excessive inertia also means that ram air kites to have a much narrower "sweet spot" for unhooking, which is one of the reasons ram air kites are poor choices for wakestyle riding.

- Semi-rigidity improves consistency, stability, turning, and handling. It means inflatables are able to withstand gusty conditions better than ram airs. Ram airs often fold, collapse, and twist in gusty conditions. Kite makers are always looking for ways to make kites more internally rigid, eg by joining the struts firmly to the leading edge, adding fifth lines, and bridles.
- For stability problems in ram airs stemming from lack of internal rigidity, see: ... sc&start=0
- Inflatables have a consistent foil shape because they are semi rigid. Rams deform and change their foil shape which causes an inconsistent aerodynamic profile.

- Far from being a hindrance, the tips of inflatable act as rudders, enabling faster, more controlled turns.
- When in the air, the semi rigid tips of inflatables create a "sled effect" whereby the kite sits stably and predictably above you. This effect is noticeably less in bow kites and ram airs.
- Rigidity facilitates turning. Bar input TWISTS the WHOLE kite, causing a rudder effect at the wing tips to accelerate turns. Lack of internal rigidity means that rams can't twist as aerodynamically as inflatos, meaning their turning and feedback is sloppier and less precise.

- Luff curves vary extensively. Inflatables with flat luff curves sit forward in the window whereas inflatables with deeper luff curves sit further back in the window. It is the same principle as sailing: If you want more "bottom" end with a sail, you deepen the luff curve (eg letting out the outhaul on a sailboard). If you want more "high" end, you make the luff curve shallower (eg sheeting in the outhaul on a sailboard). There is a lot of difference amongst luff curves on kites; this determines a lot of handling differences. It's a matter of trying different inflatables until you find one you like.
- The excessive drag and inertia of ram airs causes them to sit further back in the window compared to inflatables. Hence, there is less scope for ram designers to modify the luff curve.
- Because of the semi-rigid structure inherent to inflatables the luff curve is much easier to standardise and maintain. Semi rigidity actually enables variables like the luff curve to be really optimised. Ram airs don't have this capacity.

- Ram lovers make a big issue of this. It isn't a big issue. Beginners find relaunching inflatables easy after a few sesssions. Yes, some rams can reverse launch, but so what... a lot of inflatables can reverse launch. Rams can launch directly downwind in the water, but so what... so can a lot of inflatables. Anyway, downwind launches are dangerous for beginners because of the risk of being flung or carted downwind. For intermediates and above, relaunching should not even be considered in the equation because a) they won't be dropping the kite much anyway and b) Relaunching inflatables is EASY. Commonly, ram airs will not relaunch properly because of twisting, bridle tangles, or waterlogging. These aren't such big problems with inflatables.

Inflatables are safer than ram airs because:
a) Downwind launches are bloody SCARY and can be dangerous. Eg viewtopic.php?f=1&t=2359529 . Because only a small bunch of slightly odd people use ram airs, there is confusion about their correct use, leading to potentially dangerous situations eg viewtopic.php?f=1&t=2360971
b) Because they lack internal rigidity, rams deform, twist, wineglass, and jellfish in the middle of the power zone etc when they are downwind of obstacles, in rotors, and in VERY gusty conditions. This is VERY dangerous. Some of the most frightening kitemares witnessed have involved ram users in gusty conditions - their kites have been virtually uncontrollable and have endangered both the rider and other beach users.
c) Surf conditions
-- While it is always a gamble if your kite gets caught by a wave, at least you've got a fighting chance if it is an inflatable. If it is a ram air, it's all over.

Bridle tangles are disturbingly common with ram airs. Check this thread viewtopic.php?f=1&t=2354115&start=30
In particular, note the statement by "schmoe" that goes: "A bridle tangle on flysurfer can mean that you do not go out... For me I had many lost hours where the wind is cranking because of the bridles. I rather inflate 5 tubes and know that the setup time is exactly 10 minutes, no more no less, than have setup time that is 70% 5 minutes and 30% an hour. And now with one pump, the setup time of a tube is less, so it is not an advantage of the foil anymore."
Ram air bridle tangles can be very dangerous. A lot of riders have reported how their ram airs caught seaweed in their bridles, causing their kites to wineglass and spin out of control.

Bridle breakages occur surprisingly frequently with ram airs. They can be expensive (US $500 plus) (eg see the thread titled "Flysurfer Warrior Exploding:" phpbb/viewtopic.php?t=4612 ) .

- Ram users struggle to pre-inflate their kites in a lot of situations eg cross- offshore conditions. I once witnessed a Flysurfer lover trying to launch at a point break in cross offshore conditions. He had to get a friend (inflatable rider) to grab one tip while he grabbed the other tip and they both ran up and down the narrow strip of beach, trying to pre-inflate - to no avail. He had to pack up and go home while the inflatable riders were able to do drift launches. Without pre-inflation, ram users find it very difficult to drift launch, a skill that is often required eg Promontory/headland launches.

- Contrary to the propaganda of ram lovers, ram airs and inflatos have similar lifespans. The major determinant of lifespan is obsolescence. In 2-3 years, whatever you're using now won't be worth much and will be superseded.

- Ram air repairs are generally a LOT more expensive. For example, this phpbb/viewtopic.php?t=4612 required a PARACHUTE repairer to fix his kite, costing well over $1000. Bills over $1000 are common, eg viewtopic.php?f=1&t=2348790
- In the first example above, Flysurfer refused to honor the warranty, even though the kite was less than a year old.

Ram lovers frequently make ridiculous claims about upcoming competitions that they will "dominate." They then go on to get blown out of the water. For example, they said that various kites from Flysurfer (Psycho, Silver Arrow, Warrior, Voodoo, Titan, Insert Name Here..... etc) would dominate the pro kitesurfing circuit. It has never happened. No ram riders have ever made it into the top 20 on the PKRA - ref . Ram lovers said ram airs would dominate the Cabo Verde Wave event... They didn't. They said ram airs would dominate the "low-wind" showdown in San Diego - They didn't. The top pro riders ALL ride inflatables because of their superior aerodynamic properties. It's interesting that ALL the world records in hang-time, as well as unofficial records like Eric Eck's crazy jump, are held by inflatables. Ram airs aren't even on the same page.

Check out this thread viewtopic.php?f=1&t=2355153 Not only are inflatables superior on water (because of better aerodynamic performance, jumping, stability, and safety), they are also superior on snow and land for the same reasons.

Ram airs are inferior light wind kites for the following reasons:
1) Excessive drag (bridles, lack of internal rigidity), compromising the Lift/Drag ratio
2) VERY slow turning
3) Inertia. The Speed 2 19 contains over 11kg of air in its pockets, compared to about 3kg in the largest inflatables.
4) Bridle failures and tangling
5) Wind dropouts and gear failure
--EVERYONE experiences a few gear failures (eg broken lines) and COMPLETE wind dropouts every year. You're usually safe with an inflatable. It can be used to "self-rescue" or you can swim in with the kite. If things go REALLY bad, you can just use the inflatable structure to support your weight.
--ALL ram airs become hopelessly waterlogged after 45 minutes - unlaunchable and certainly unable to support your body weight.
eg viewtopic.php?f=1&t=2346569
eg viewtopic.php?f=1&t=2358958&p=608890#p608890
eg viewtopic.php?t=2359156&p=617396
-- The following is an example of "diraklib's" experience with ram airs in wind dropouts: "the SA-19 is huge and can whack you silly if you let it get down wind of you in a low wind launch. It is downright scary - be ready with the QR at all times if not up and riding!!! I can't say I agree with claims that you can ride the SA-19 in anything lower than a steady 8 knots. I made a personal choice to not ride the SA-19 any more. It went down twice in lulls and managed to bow-tie on the way down - there was no way to relaunch. I was not as lucky as others that self rescued. My kite was full of water by the time I dragged my very tired and frustrated a$$ to shore. It sounds simple, "wrap the lines around the bar, fold the kite in half, roll it up on your board and paddle in"... noooo... there are lines everywhere under water that wrap around your feet as you are trying to manipulate the kite. You just pray that a gust won't pop the kite up and slice of an appendage. The kite ... is just too scary when it goes down. My attitude now is - if my LEI won't fly, I shouldn't be on the water. Anyone interested in a slightly used SA2-19m??? Cheap???" For the full admission, checkout the following link: viewtopic.php?f=1&t=2360979&start=40
6) 8 knot limit
-- Despite what anybody tells you, you won't really have fun on any kite (ram air OR inflatable) unless the wind is over about 8 knots. This is the starting point for BOTH ram airs and inflatables, but because of the reasons I've outlined above, inflatables are vastly superior. And this is just the starting point. You won't really be having fun until it hits about 10 knots on an inflatable OR a ram air.
- Ram lovers are prone to exaggeration and just plain misinformation about light winds, eg see the following thread: Ram airs jump 8m in 8 knots ("The future is bright, the future is foil") ... &view=next
gmb13 wrote: Please let me know which Kite you use that will allow me to get out in less than 5 knots. My Speed 3 19 DL gives up under 5 knots, so if you could please let me know about a flying tyre that will outdo my Speed3 please let me know Gunnar
Gunnar Biniasch has been caught out exaggerating the benefits of ram airs - typical ram lover lies and exaggerations. NO kite - ram air or inflatable - will perform in under 8 knots and definitely NO KITE WILL PERFORM UNDER 5 KNOTS. I won't go into the physics of it, but it is simply impossible for a kite to perform under 8 knots; definitely NO KITE WILL PERFORM UNDER 7 KNOTS. The physics is complex, but primarily involves the power that wind moving at 7 knots (13km/h) can deliver. There is simply not enough power or velocity at this wind speed for ANY kite to perform.Gunnar's exaggerations and lies can be found at viewtopic.php?f=1&t=2361421 This is typical of the ridiculous and unsubstantiated claims made by ram lovers. Kitesurfing in under 5 knots.......laughable. :lol: :lol: :lol: :lol:

7) Objective Testing
-- A variety of kites were tested in light wind conditions in San Diego a few years ago viewtopic.php?f=1&t=2319439&hilit=ram+a ... +san+diego . Despite the ridiculous over-hyped claims from Flysurfer reps like Ted Bautista, Flysurfer ram air kites crashed and burned. The overall consensus was that Flysurfer ram air kites are ok in light wind, but they turn VERY SLOWLY. The overall impression was that there are much better inflatables. It's interesting that a lot of the ram air guys who were excited about this showdown were remarkably SILENT afterwards, in particular, Ted Bautista, the U.S. rep for Flysurfer. His alpha-male chest-beating rants in the lead up to this showdown almost defied belief.
For an example of the LIES that ram lovers tell about their kites, checkout viewtopic.php?f=1&t=2350141&p=539227#p539227
8 ) Flysurfer and Light Winds
See the thread about the poor light wind properties of Flysurfer viewtopic.php?f=1&t=2349064

Amongst inflatable riders, there is a certain amount of collegiality. Inflatable riders tend to hang out together and help each other on the beach and on the water. If you fly a ram air, you'll always be a bit on the outside; regarded as a bit weird and not really part of the group. Part of this is because you will always be in a minority on the beach, part of it is because ram airs are so rare that inflatable riders are a scared/unsure of ram airs, and part of it is because, as a group, ram rides ARE a bit weird. Anyway, one of the problems with being part of a weird minority on the beach is that it can be very difficult to find people to help launch and land your kite, eg ... C_ID=51465

Ignore the ram air propaganda. Ignore the lies. Ram airs are aerodynamically inferior to LEIs and nothing can change this.

Maybe you should reread your entire post. And then explain to us again... who is the "geek" here?

Now now PMU,

I gave you the ise vice ize but this simply can not stand. After you berated Fred for his spelling and called him retarded for being unable to properly use the language you go and show that according to your own rules you are indeed retarded.

Here are some examples taken from your above post. I did not do an exhaustive review of all your postings but I am sure there is more to find.

It is e.g. not eg.
It is sessions not sesssions
It is water logging not waterlogging.
It is a jellyfish not a jellfish.

For those of you that might not know what this is about, PMU told everyone in another thread what a great user of the English language he is by calling people with spelling and grammar errors in their posts, retarded, the correct term is special needs PMU. Retarded is a now considered a pejorative. I am just demonstrating that PMU is indeed a special needs individual and thus can not be trusted for his opinion, per his own rules laid out in another thread.

Ha haa - I did not knew he still wrote, till you started this thread 8)

As I've had "Experimental Player" and "Pump Me Up" on my "foes" list for a long long time now, so I have never seen a post by any of them for a long time :D

Works perfect with this feature :thumb:

Don't know him - but I think he has a lot of very valid points.

But in the end if you are a ram air / foil type of guy,,,,good luck to you.
