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.

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!
Chad
