I'm having a problem with the FEDS regarding medical issues, and it sounds like the sport pilot plan may be all I need to be happy in my flying career. I would guess that the primary structure may be adequate at the reduced flying speed, and that we could "Hershey bar" the wings and add span to meet the requirements.

If any airplane should be short-coupled and pitch sensitive (just by observation), it would be the Questair Venture. But it isn't (read the flight test info at http://www.airbum.com/pireps/PirepQuestairVenture.html ) so it must be "something to do with the elevators" ;o) Far better minds than mine have tackled this issue and have come up with redesigned tails, aerodynamic counterbalances, different linkage ratios, biasing springs, and other things to change the pitch feel of the KR, and the jury is still out on many of these things because they haven't flown yet. But I'll bet that by this time next year there will be some actual data posted here, so stay tuned.

Using those numbers, you would have a tad over 4 hrs. endurance and a range of 720 miles. But to be realistic, using VFR reserves and allowing for unusable fuel, (not to mention personal endurance limits) you could say you could preflight a solid 3.5 hr. typical flight leg time and around 650 SM no-wind range and nobody would argue. But everyone knows that only the KR in the Rand-Robinson promo literature cruises 180MPH anyway ;o) Oscar Zuniga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net _________________________________________________________________ Add photos to your e-mail with MSN 8.
