Riser turn estimate

[ManBird 0]

Crossfire (1) 109 loaded at 1.7. Flying it tomorrow. Trying to mentally prepare a bit. < 1,000 MSL, 75 degrees tomorrow. 650 - 700 ft for 5 seconds in a slow front riser carve?

650-700ft seems a bit high to me, but then again, I'm flying a Heatwave, not a X-fire, but at the same wingloading.

I usually go into my carve at 450ft.

BUT it is much better to be high then low.

Yeah, I'm definitely not hooking it right down to the basement on the first one.

that may be a bit high, but just try it. if it's too high, eithet A. use that same altitude and make that turn longer or B. use that same turn, but start at 550 instead of 650, and so keep going a bit lower until it is right.

I start my turn on my velocity (180 riser) @ 650-700 ft. That been said my first jump on it I landed straight in, then started working up the turns until I got back to my 180.

I personally feel it's always a good thing when stepping down to a new canopy size and type to start at the very beginning and work up over a few jumps - not only is it safer, but I find it helps me get dialed in quicker, but thats just my opinion.

Either way be safe and have fun. I'm sure you'll like your new "toy"

Thanks a lot. I'm essentially going to spend the whole jump (dumping at 13k) checking the flare and front riser turns (monitoring the alti to see what I'm losing). On final, I'll probably front riser and only get through about 2/3 of the "power band", so as to have forward speed, but not exactly a swoop, for a straight-in landing without bringing it to a halt.

My Sabre 120 drops about 350 feet in a 4 1/2 second riser turn before the riser pressure goes way up. I know that there is a big difference between these two canopies. I was just trying to more fully form a hypothesis before the "experiment".

My Crossfire 139(original) loaded 1.4 with weights and camera stuff. 300ft. 180 degree front riser = massive swoop.

I can believe that. How long (in seconds) do you spend on a 180? You can snap a 180 and only drop 280 feet, or you can spend a full five seconds on it and lose 500+. That's why I'm more interested in the altitude loss over time, rather than the degree of the turn.

I'm not making assumptions or criticisms or anything... I can drop my Sabre 120 350 - 400 feet with a 180 that I spend my entire power band on. I would assume that the same kind of turn would drop much more on the XFire.

Ya, that's a snap turn for me. I'll hold a 270 carve for about 3-4 seconds at about 400 ft. I can't hold a carve for much longer than that, the riser pressure is too great.
