    Well all...... Here is my update! Flew the airplane this weekend past with a 30 plus year , 25,000 hour pilot! It was my only option, as even Zenair didn't have anyone they could reccomend. So, we just went at it. First flight was scary, as we had a BRUTAL propellor vibration and had to get her back on solid ground. We could only muster 4800 rpm! It still climbed 700/min. Changed the prop, hub and spinner from the GSC wooden, set pitch to 14 degrees and went at it again! WOW!!! Climbed 1300'/min at just shy of gross, with a cruise at 5100 rpm of 105kts! Open it to 5200 and I see 110kts all day. Fuel burn was amazing, and all worked well. Oil temps creeped a bit, and I think they'll give me some issues. Any idea if a tab of aluminum under the cowl will help like on the 701's? My cooler is fed by two naca openings. I just don't think the cowl is venting properly. CHT's are great though. So, onto the flight review. We flew 5 hours which is what the insurance co wanted. I flew the first half in the right seat with no brakes, radio access to tower and a crappy T-Bar throttle. I made my first 7 landings there! Not a problem at all. Only two issues we found was that it shoots off the runway abruptly, which I'm thinking is too late of rotation. 65kts or so. The second issue was the landings. No matter how hard I try to hold the nose off, it still THUMPS down HARD! Flapless landings went better then expected, as long as you slow the airplane WELL in advance! It refuses to slow down actually! Lol I performed the balance from the left seat, and was at home there! I flew the airplane completely unassisted the first time, and needed no help in doing so. What a beautiful airplane!!! Killer climb, GREAT cruise..... I'm not touching a THING! Seems set up PERFECT! I don't even run out of trim like everyone else on final with full flaps. It CAN be tricky in the flare solo, wanting to float for days, but almost ALL of my landings were still inside 400'. I LOVE LOVE LOVE LOVE the airplane! However, I am still a little nervous because of all the bad press the airplane has had over the years. But, if it doesn't try to kill me, and the engine runs as well as it does, I'm IN LOVE! MAN! What a plane! Now...... If I could figure out how to get that nose wheel lowered without the thump...... It would be perfect. Total weekend, 5 hours, decent conditions, breathtaking climb rate, and I'm MORE then content with 100kts getting 3.7 gal/hr burn! Just..... What. A. Ride! I went for a solo flight, and didn't really notice the missing 150lb instructor. Same climb, same cruise, but floated on landings much more. I love that Rotax 912ULS. I'VE got the airbox, so I'm sure that helps with power. One MAJOR thing I noticed is how on a takeoff, application of power was unreal! Really pushes you back in the seat on take off and climb out. Feedback encouraged! Either way, the type training is done, very successfully as well! Thanks for all the help! Chad C-GYXQ Photo below is after 20 landings and five hours of flight time. She LOVED it almost as much as me! Here is the second flight quick video. http://youtu.be/4r4VVXhYZuI Ps..... It is for sale. $35,500 cad. Not sure ill have the time to fly as much as I'd like this year. Three kids and one is a newborn. I'm a busy guy.... :-( -------- C-GYXQ. 912ULS. 601XL-B Read this topic online here: http://forums.matronics.com/viewtopic.php?p=401157#401157 Attachments: http://forums.matronics.com//files/image_164.jpg

    I put VGs on the elevator of my 601 HDS and that stopped the thumping of the nose. I can hold the nose off as long as I like now. Nice airplane.

    I should have said that I installed the VGs on the horizontal stabilizer, not the elevator.

    Hi Chad, I'm far from an expert after around 50 hours in my XL. Still, I will try to answer a few of your questions. On take-off it sounds like you are waiting too long to rotate. If you take off with no flaps your stall speed must be no more than 45 knots. If you use flaps (like I do) it is even less. You might try rotating shortly after you start your take-off roll and let the plane decide when to fly. I've found 1/2 flaps to be ideal for take-off. Full flap take-off works but the airspeed isn't enough for good control in the first stage of flight. I've never measured my take off roll but I would guess it is between 200 and 300 feet. Of course your take-off roll will be longer due to your smaller engine - I have a Jabiru 3300. On the landing issue - it sounds like you are not slowing down enough on your final approach. I try to approach around 60 knots but that is probably too fast as well. Ideal approach speed should be 1.3 times your stall speed in your current configuration. Excess float on landing can be fixed with flaps and slower approach speeds. When you get close to the final landing altitude you should adjust your pitch to your desired landing pitch (this is called flaring). If your pitch has the nose just above the runway on touchdown it seems unlikely the nose will crash down. If you touch down with the nose wheel very high then it can fall and hit the runway harder.
