There's no question that they are slightly more difficult to land (and perhaps, to a lesser extent, take off). And yes, modern design has managed to reduce the impact of tricycle gear. It doesn't eliminate it, but it certainly reduces it. But it begs the original issue. Is the limited performance we have with LSAs such that we should seriously consider trimming all the weight and drag we can, to the extent of considering tail wheel aircraft? The 601/650 is one of the better designs around (the best, in my judgement), yet it could still use all the additional payload it can get. Tricytcle gears usually weigh more than conventional gears. There isn't too much obvious additional reduction in drag one could get, other than maybe going to a conventional gear. I say all this with considerable trepedation. By the time I began taking flying lessons (1968), most training was done in tricycle gear aircraft, and I've never flown a conventionally geared aircraft. Still, if money and other factors permitted, I'd still be flying my Cherokee 180, so I must consider all factors before making a final committment. > They also eat runway lights for breakfast... :-) > ----- Original Message ----- > From: Gary Gower > To: zenith601-list@matronics.com > Sent: Wednesday, September 03, 2008 12:59 PM > Subject: Re: Zenith601-List: Re: 601XL/TD > > > Paul: > > Real Pilots fly Tail Draggers > > Real Bikers ride Kick Starters > > :-) :-) :-) ;-) > > Saludos > Gary Gower > PLEASE Do not archive. > > > --- On Wed, 7/30/08, Paul Mulwitz wrote: > > From: Paul Mulwitz > Subject: Re: Zenith601-List: Re: 601XL/TD > To: zenith601-list@matronics.com > Date: Wednesday, July 30, 2008, 10:02 PM > > > > There are some down side issues with tail draggers too. > > Tail draggers have much higher accident rates than tricycle gear > planes.

Just how much does the 601's nose gear weigh? One of the questions I was asked when I was getting insurance was whether the airplane was a taildragger; it would have been significantly more expensive if it had been. When you consider that the insurance industry views LSAs with deep skepticism due to their accident rates, adding taildragger into the mix would be a big hit. -- Jay Maynard, K5ZC http://www.conmicro.com http://jmaynard.livejournal.com http://www.tronguy.net Fairmont, MN (FRM) (Yes, that's me!)

I'd like to see what the plans themselves look like in that area. Do you have any pdf files of the wing structure and center fuselage structure where the wings attach? I'd be really interested as to what that looks like on the plans.

I'm not sure I understand ... do you mean the TD weighed more than the tricycle version? I would have expected the reverse. If the coventional gear weighs more than the tricycle gear, then the choice would be more obvious. I have asked Zenith the question about conventional gear vs tricycle gear weight, and was told I'd get an answer right after Osh. It may be that everyone is busy with the new variant coming out, but so far, I don't have an answer. -- ============================================= Those who can, do.
