    Thanks everyone for all the feedback! I agree, that the rotation speed is too high. As for the landing, I cross the numbers between 60-65kts. I go into the flare, and the mains touch ever so lightly, and I hold the nose up as long as possible. I think this is where the issue is arising. With the nose held off, it suddenly loses elevator authority on the rollout and drops the nose. Next time I fly, I'm going to try to lower the nose fairly quickly, or maybe even fly it onto the runway at a lower speed. These are all flapped landings, usually using full flap on final. I mean, other then these two items, she comes off with authority and flies really well. As for the lesser power of the Rotax, I've flown a jabiru 3300 in a 601XLB and it had no where near the pull this Rotax does. It accelerates like nothing very rapidly and climbs unbelievably. This is actually the most surprising part of flying this plane! It still shocks me every time I advance the throttle! The airspeed winds up fast! Thanks again!

    I turned my undercart around, when I upgraded to the 'B', best thing I ever did, I can hold the nose off, right down to walking speed. Can do a really short field take-offs - as I can lift the nose wheel long before she is ready to fly. Only thing to watch out for is a heavy passenger climbing in, she can tip on her tail. Jonathan 500hrs + and loving it. -----Original Message----- From: SIDESLIP Sent: Thursday, May 23, 2013 3:40 PM Subject: Zenith601-List: Re: New to aircraft, flying tips needed. 601XL-B Thanks everyone for all the feedback!

    Hi Chad, I understand your Rotax works well and the Jabiru you flew had issues. Perhaps the big question is what propeller is used. Many Jabiru installations use the Sensenich ground adjustable propeller which is really designed to work with the Rotax and doesn't do well with Jabiru. My plane uses a wooden Sensenich propeller (64ZK49) and accelerates quite well. The extra 20 or 30 horsepower should be noticeable in all realms of flight. You may also find a tiny change in the propeller pitch has a large impact in both acceleration and cruise speed. I agree with Johnathan's comment about the installation of the landing gear spring. You need to have the flat end forward. Older drawings show the flat end aft and the angled end forward. This moves the main gear back a few inches and puts more load on the nose gear. You really want the main gear to touch down before the nose gear, but you don't get extra points for having the pitch any higher than necessary to guarantee this. If you hold the pitch higher than necessary then the fall of the nose gear can pick up enough speed to slam down on the runway. If you lower the nose at a high speed you may find the nose gear isn't very happy. You really want to hold the nose off until the elevator won't hold it any more.
