There is an option for a lighter rudder. Moves CG fwd about .75" because it is about 20# lighter than a fast build rudder. All for the low price of 20amu. Yikes. Oh also remember your CG moves aft with the wheels up. But the CG limits take that into account.

It does get pitchy when aft. But not terrible. I plan on redoing my panel and interior. When I do I plan to take the opportunity to move anything I can forward. I'd like to lighten the rudder. But the 20k coming out of my wallet up front would offset any gains. So that's not happening. Been considering adding tks to it. But that's a lot of work. Brad and I were talking about rebuilding the leading edge so the panels would closely resemble the original airfoil. But that would involve slicing the front off. Sounds worse than it really is. Not to go fly all over in ice. But as an oh sh$! Card. Live in MN so limits the winter flying. Usually icing here in winter is only a few hundred feet thick though. On the other days total no go.
How does your ES load up?

The ES is Like a station wagon frankly, it will haul pretty much any configuration i've thrown at it so far, 50% more wing area will do that though- for my mission, the ideal plane would be a turbine ES-P, i've talked about doing one with brad, if an unfinished kit or opportunity comes along, i think we'll give it a go, i want the reliability/stability of the ES wing/gear, and the climb rate/smoothness of the turbine, my flights are 250nm or less, so 90-104gal of fuel is plenty of reserves at 35gph cruise burns i LOVE the evolution but for 1.5m to go 250nm, it doesn't make sense-

What is the diff between that and IV-P ES-P has same fuselage but fixed gear, 40% larger wing/tail area, excellent safety record, cheap ~(300k hull around 3500/year) insurance http://www.controller.com/listings/airc ... ncair-es-pI think this guy would be good in the mid 200's, he just put it on eBay and it didn't sell, highest bid was 180k didn't hit the reserve, when i see people listing airplanes on multiple different sites, changing prices weekly, and then resorting to eBay, i assume they really are motivated to find a buyer

Username Protected wrote: thank you. 6'3" 240 any problem you think? well, it's an experimental- you can adjust the seats as you like, some sit comfortable, some sit cramped- easy fix of adjusting seat attach points and rudder pedals, mine is like a cadillac- seats out of a sports car, european leather, seat heaters....inflatable lumbar... i'm 3" shorter than you and have plenty of headroom, i imagine it would be similar to a cirrus- thing is, you'll have the same fit in a IVP that you would in an ES or ESP

First off, a T-6 breaks cleanly, but there is no scenario where it requires 8000 feet to recover. I do lots of T-6 training and I full stall them, including falling leaf manuvers all the time. A base to final cross controlled stall will tuck under and roll. Even that will lose less than 1000 feet. Secondly, I have stalled a Cirri, and it is recoverable from stalls normally. It is not spin certified, but I have personally talked to Cirri test pilots who have spun and recovered in Cirri. The Cirri was going to have a parachute from the outset, so they saved money and gained performance by foregoing the spin certification in favor of the chute.

It's been awhile since I stalled an SR22, but my recollection is that the stall characteristics were pretty benign. IIRC, that's the primary purpose of the "cuff" on the wing. I also believe that Cirrus did do spin testing in Europe as part of that certification (but I might be making that part up).
