Just do some jumps with a GPS and fly chasing whatever you want to chase . Then post the log if you can sustain a vector velocity of 80 mph while also getting a decent L/D of like 1.8. Then you will understand what I am trying to say. Kris.

The point is that even if exiting in the opposite direction of flight has a 25% effect(this is equivalent of being at the exit point going the right way, 400m lower than where you first exited...impossible if you turned immediately.) on the overall L/D, the total speed is 96 mph, still too slow. Kris.

Exit in opposite direction to flight path does not do anything, if, you did a fast turn. If average downward speed was 39mph, the total speed is 80 mph. I don't think 80 mph total speed is fast. It can only be achieved by someone of your build if they are flying at a high angle of attack. Since you were flying better than Robi and we all know that he will Instantaneously Combust if he flies at a high angle of attack, that 1.8 does not make sense. Unless, you don't really know how to fly for distance and Robi was just messing with you. Kris.

Exit at 2500 meters, opening at 900 meters. I can only estimate glide ratio (covered distance) to approximate 1:1.8 (without wind). At particular jump I was more concentrated not to be catch by Robert than to the ground marks... 1.8 is too low an estimate. Kris.

Boris, 39 mph average on straight line flights is definately possible on a Phantom. I asked Robi this question in PM. Can anyone (while flying for distance) fly a slower vertical speed(average) out of an airplane than they can on a WSBASE jump? For a WS BASE flight the following factors are favourable to having a slower vertical average speed. a) Lighter rig(especially the rigs with the Trango canopy) b) Denser air. Kris.

Jarno, If I was a moderator, I would have deleted the quoted post. Kris P.S: Still Suspicious?

Hey Boris, Who is flying from Smellveggan(exit altitude 930m) in the Kjerag_07.wmv clip? Robi emailed me that clip, I am assuming it was him. That is a 46 second flight(44 secs thru 1 min 30 secs). Assuming 150m opening altitude, that is an average vertical speed of 38mph. I would be a bit skeptical of any reading of lower average vertical speed while flying for distance from an airplane than my average vertical speeds on a WSBASE jump flown for distance. These numbers you have quoted, what is the exit altitude? What kind of airplane(exit airspeed)? Kris

Yup, a 1.7(distance challenge numbers) is hardly worth mentioning these days while talking about big suits. He later posted 2.4 L/D for a 7000' flight(vertical altitude used). Would like to know what it is these days if he has that data handy. Kris.

You know me...I usually don't care about fallrate, but 34 mph average fallrate is fucking impressive. Kudos. Kris.

You should stop pulling the numbers out of your, errr, back door. If you spent one sec thinking it would have been obvious that the 157.5 was posted to show that 75 mph is an unrealistic downward speed. Jeez, you seem really eager to jump at a chance to ridicule me. I gotta ask. Did ya score some brownie points? The 2.1 came from this post . Are you in the habit of posting numbers out of your, err, back door?

Possibly the ability to use a calculator or keyboard

Jeez . I was being sarcastic with the 157.5 mph. About the 15m/sec, he was not talking specifically about the prodigy. But said any speed sustained below 15m/sec in GPS data should be discarded as spurious. Kris.

Yuri posts here as Outrager. 75 mph is way too much downward speed. Yuri is flying his Prodigy at 2.1 L/D that makes the forward speed 157.5mph. The other way around it is 35 mph vertical. This is what Yuri has said (15m/sec in his words) is the ballpark vertical speed at best glide. Kris.

Czech Martin said you were flying back to the landing area at the ITW. That is no easy task. Please post your thoughts. Kris.

Body position may be different due to the shape of the suit but if you want to fly for glide, the most important thing is the angle. Fly steep. Kris.

We have a long way to go... Justin, Based on what I have seen, I'll skip buying this version of the suit. Have you flown the Apache steep? I mean like 10-15 degrees steep? Please post your findings or PM me. That is how steep wingsuits must be flown for best glide during a BASE flight. Kris.

Solid arm wing inflation is more important than leg sleeve inflation. The shoulder inlets also inflate the legsleeve. To do this the air has to inflate the body of the suit first. Look at the location of the shoulder inlet and the paths the air has to take to inflate the armwing and the legsleeve. The air will prefer to flow down the body to the legsleeve vs force itself into the end cells of the armwing. If the wrist is just a tad loose, the air will want to leak out from there instead of inflate the end cells. Its not rocket science. The inflation is closely tied to the volume of the suit. To inflate the suit a given Net* amount of air must enter the suit per sec. Are the inlets dependent on the net volume they have to supply air to? To supply air to a suit with more volume, the inlets must be bigger or the speed at which the inlet is moving thru the air must be faster. In other words, the inlets will only provide the required level of inflation in certain conditions. This is what makes the performance of the suit very closely tied to fit. A bit too loose and arm wings may not inflate correctly. Kris. * air is entering and leaving the suit from several places, not only the designated inlets and outlets.

Only in your mind. All I am saying is that there is room for improvement on the V2 (more consistent inflation of the arm wings. The legwing has solid inflation BTW) and that it is beneficial to everyone if more manufacturers make wingsuits for BASE. I want more choice. Kris.

Thanks. Arm wings don't look like they are too much bigger than V suits. It seems to have back inflation vents(?). Would prefer having a bigger legwing. Kris.

Do you realize that you are implying that Robi is flying using an incorrect body position ?

I was refering to Arm wing flap Luka. To make it even more clear. Look at how the air entering the shoulder inlets has to travel along the body adjacent to the cutaway tabs to reach the leg sleeve. Cutaway tabs are used as air inlets in many suits. So the bottom cutaway tabs would be inlets and the top cutaway tabs would be outlets. This would make the performance of the suit very sensitive to how the tabs are made. I can put a finger thru the gap at the top of the tabs on each side. If I take the suit to the DZ(flying a canopy I won't jump wingsuit with) this weekend I'll post a picture. Also note how there is less restriction for the air to move along the body and to the leg sleeve than for the air to move towards the far part of the arm wing. Kris.

Cool

Tony, The biggest suit(due to lower wingloading) will look like it is kicking everyones arse at Breakoff. This may not always be true if the same people have an opportunity to have an even race. Like the one you guys had at Zhills and the one at Stupino. Yuri, Even BASE has its fair share of polluting factors. a) Zero winds at the landing area don't always mean zero winds all the way to exit altitude. Even though we like to sell it like that . b) Like any glider, if the mountain allows flying in the region of local conditions(ridge and thermal lift), a wingsuit pilot should take advantage of this. Smellveggan allows 1100m+ of the flight to be in a region of ridge and thermal lift. ITW has strong updrafts in the bowl. Best taken advantage of during the cooler months. Best glide performance at a mountain is always tied into the local conditions. Having said all that the best suit someone can get for BASE is a V2. That is not to say that the V2 does not have problems. Just take a look at 'Fly the line'. The V2 itself can be improved a lot by making the armwing inflation more consistent. Any suits that will perform well in the BASE environment will look like the V2 Planform. The sooner more manufacturers realise this, the better. Afterall, PF has gone in a new direction with the Ghost. Why can't other manufacturers do the same? Kris.

Based on Mike Ehlas's description of how the suit is built, it seems like every other one of Tony's suits. With a worse characteristic...a narrower(as narrow as an S3!??!?) legwing. Any BASE suit should allow a PC location that can be reached in full flight with no chance of the wing covering it. That is why any suit with a arm wing root extending too far below the hips is a no no for BASE. Don't think I am knocking Tony's suits. I simply don't believe in that design. I'll gladly pay 2-3 times the price he's charging for his top suit if he make one for me with the characteristics that I specify. Kris.
