Macx Posted December 13, 2003 Report Posted December 13, 2003 Hi, does anyone know, why Flexifoil has changed the wingspan of all Blade III on there specification page. I thougt the wingspan of my Blade 6.6 is 5m. Now there are other values. Blade 6.6 = 5.8m wingspan. Were the first values wrong?? THX and Greats Nils Quote
Adrena1in Posted December 14, 2003 Report Posted December 14, 2003 There was a post the other day where someone was questioning the Blade 3 wingspan. Flexi has stated 4.3 metres for the 4.9 Blade 3, whereas the Blade 2 was 5.2 metres. It seemed Flexi made a mis-print...and it looks like they're corrected it. (...goes to the Blade 3 specs page...) Well whaddaya know. By a simple calculation for aspect ratio, I calculated the 4.9 Blade 3 would have a 4.95 metre wingspan, as opposed to the 4.3 that Flexi stated. The spec. sheet now says 4.95 metres. Quote
Airborne1599968603 Posted December 14, 2003 Report Posted December 14, 2003 Adrena1in - what is the formula that you used for that calculation? Quote
Adrena1in Posted December 14, 2003 Report Posted December 14, 2003 Aspect Ratio = wingspan squared / area. For the 4.9 Blade 2 this means : AR = 5.2 * 5.2 / 4.9, which = 5.518 For the 4.9 Blade 3 we knew the area and the aspect ratio already : 5.0 = x * x / 4.9. Therefore, x * x = 5.0 * 4.9. x * x = 24.5. x = 4.9597 Quote
Airborne1599968603 Posted December 14, 2003 Report Posted December 14, 2003 Cheers, but I'm sure mine is less than 4.7M wingspan from when I measured it for that previous post you mentioned. I feel a letter coming on... Quote
Adrena1in Posted December 14, 2003 Report Posted December 14, 2003 Perhaps, because I'm always right, Flexi just took my word for it. At the end of the day, does it really matter? Quote
Airborne1599968603 Posted December 14, 2003 Report Posted December 14, 2003 Probably not - if it had been any bigger today I would have looked like a splattered fly on a car windscreen... Quote

What do you mean?! If Flexi had misprinted and said it had a 49.5 metre wingspan, rather than 4.95, it'd still be the same kite, with the same power. Quote
Macx Posted December 15, 2003 Author Report Posted December 15, 2003 Hmm, that was my problem: Since now I own two Super10. Each one 2.86m wingspan as you know. Two weeks ago I thougt: Lets buy a traction kite. Blade sure, but witch size??? 4.9 or 6.6! I compared the wingspan of the super 10 (2.86) with the wingspan of the 4.9! Only 1.5m more (Flexis first quote: 4.3m) than the super10. I decited to buy the 6.6 with there 5m wingspan. But in real its 5.8m now, couse ot Flexis misprint. I'll hope I can handle the kite. Quote
rasga Posted December 15, 2003 Report Posted December 15, 2003 its a VERY big leap, the same area sized kite as a super 10 has moer power than the super 10. . all due to the way it behaves in flight VERY light winds would be wanted, or a slightly smaller kite>? Quote
Macx Posted December 15, 2003 Author Report Posted December 15, 2003 Yea sure, both are completly different. But I can only use my Super10 stack from 20mph on to have fun. So I wanted a kite for 10-20mph. I hope it was the right choise. I used the blade only one time yet. in about 10 mph wind and I could manage. Quote

What I'm saying is, that according to your formula, the kite I have is not 4.9M squared but is in fact 4.418M sq. As you say, we know the aspect ratio =5.0, and I have the wingspan = 4.7M (just re-measured to be sure) i.e. 4.7M * 4.7M / 5.0 = 4.418M sq. In actual terms compared to a kite that is 4.9M sq, this kite has half a sq. M of surface area missing. Or have I missed something, O Ye who is always right? Quote

So I wanted a kite for 10-20mph. I hope it was the right choise. I used the blade only one time yet. in about 10 mph wind and I could manage. mate, i don't know how much you weight but 2 tens are really toys next to a 6.6 - my 4.9 is good for 10-20mph - in 20mph of wind i am easily clearing peoples heads with my feet during jumps, and thats just on the way up - with a 4.9! - for all their good points you will soon get annoyed with the lack of rear lines on a pair of 10's - i would get something smaller first as the power will surprise and possibly (but hopefully not) hurt you - 3m blade 3 would be good to start on but if you have to have a 6.6, be aware it may well decide to hurt you for no reason than that it felt like doing it - i know my 4.9 has the demonic streak. you will have fun on whatever blade 3 you get, so take it safe and please don't get hurt:) Quote
Macx Posted December 15, 2003 Author Report Posted December 15, 2003 Sure your right. But I'm a student. I can't afford the money for a 3m blade. Two month later its boring and I have to buy a larger kite. The prices of the smaller blades are to high. First time I tried out my Super10s was in very strong wind. I managed it. So I have to manage this too. Normaly there is very low wind in my surroundings but I need a kite for every day. I dislike these sitting and waiting for wind. But these times are now over. Hope the rain will end up soon. Quote
the_lone_wolf Posted December 15, 2003 Report Posted December 15, 2003 fair enough, but there are going to be days now when you cannot fly, which is annoying - i know, i went 3m, 4.9m, 8.5m, and i am also a student but i got a good job;) - please be very careful with the 6.6 as it is a huge power step up from a super 10:) Quote
rasga Posted December 15, 2003 Report Posted December 15, 2003 mate. .you seem to only want to buy one kite .. . . .look at everyone and eventually you end up with at least 3! i.e i can cover most wind ranges, with a 2.1, 4m, 6.6, and shall get something bigger next year (fingers crossed) Oh. . and i am a student too, and have paid for my kites myself! Quote
Macx Posted December 16, 2003 Author Report Posted December 16, 2003 Sure I'll be very careful. By the way: On my first flight I tried out the two knots at the brake bridle. The longer one was too loose the knot near the kite was too tight. Is it right that I have to add knots in order to find the right length? Quote
rasga Posted December 16, 2003 Report Posted December 16, 2003 yep just fiddle around with it, (the knots that is ) and definately know your limits, (just so people know, i would never ever ever ever recomend a first four line traction foil to be this size) Quote
Macx Posted December 16, 2003 Author Report Posted December 16, 2003 I think my first try was ok. I'll not go out in conditions which are too difficult for me. And I'll never fly the blade in more than 10-12mph wind in the first time. And I'll never go alone. I think I'll learn when I try hard. Quote
