Anyone have a POH for a Mk3 Classic that I can use (will modify the V-speed numbers for my airplane)? Thanks.

Mark,

Did you get the info from someone?

Mark, Denny, Attached is AC-90-89A, "AMATEUR-BUILT AIRCRAFT & ULTRALIGHT FLIGHT TESTING HANDBOOK."Not exactly what you asked for, but with this you can determine all the "V" speeds, calculate take off distances, and fore and aft limits for the CG, etc.

 For first flights, use 45 for Vx (stall speed 37mph + 20%(8 mph)), and 50 mph as pattern and approach speed. The reason for the difference is that the Mk III, either version, will not do a conventional departure stall. It will just mush along on the prop.

 If the previous owner didn't set a maximum take off weight, start at 1000 lb.and work your way up 50 lb. at a time. I found 1100 lb. was a good upper limit, although I tested to over 1200 lb. in both models, but control travel becomes an issue (at 1240 lb. I had less than a half inch between the stick and the seat frame in the "X").

 Hope this helps.

I don't think it is a good idea to indicate in any way that maximum weight of any airplane can be increased just because it flies at that weight. I had a long talk with a engineer that helped design the MKIII and he would not budge on the recommended 1000 LB limit. Yes the airframe is very strong and is conservatively rated as all aircraft are. His concerns are things like builders skill, aging airframe, and turbulent air. At least one builder/pilot flies his plane loaded to 1200 lb. but only after a number of modifications to the airframe.  

 



Without a extensive background in aircraft design and considerable testing it is dangerous to recommend exceeding the manufacturer's limits.

Check your indicated stall speed on first flight.  I have been told by a very good source that 55 to 50 (no flaps) is normal for a Mark III Xtra.



Mine is in that range.  If that is the case 50 is not a good pattern speed.

If 50 to 55 is your normal stall in a Mk 3 of any flavor, you have an airspeed indicator error.

I also thought 55 was too high for stall.  I pulled the static line from the tube and put it inside the cockpit and but got the same result.



The next thing is to get some good test data with the indicated airspeed and actual GPS speed.  I've got about 4 hours on the plane but am waiting for a new fuel pump as mine was on the recent Rotax service notice.



My pitot tube is about 6" down from the nose and about 2" left.

You'll find some error in the asi for sure. No big deal as long as you know where the stall is
