Thanks god the rotax 912 does'nt need a mixture mechanic,only a choke
cable! After 15 years using a push-pull friction knob on my Kitfox I made a
simple throttle quadrant with bowden cables ,very comfortable and quick to use.

the conclusion of the German Test of the Kr Spar and WAF's calculated by
Otto Bartsch is: Any reliable built Kr with a MTOW of 1050 pounds is a 4,2 G's
plane with a 1,45 safety factor,or a 3,8 G 's x 1,6 plane!
Otto Bartsch assured me,that the calculation was carried out somewhat
Hello netters,over here in Germany ,I had to do a spar and WAF load test for my
Kr. Mr. Otto Bartsch from the OUV(the German association for experimentals and
a aerodynamic ingeneer at Messerschmitt Boelkow Blohm (MBB) did a very simple
but efficient Job.To demonstrate the strength of the

The manner how you will land the Kr is called in Germany as "Lufthansa
landings".That goes back as Lufthansa still Ju 52, DC3 and other tailwheeler

Any theories,which can be read in books and magazines are good for the head but
not for the hands.Therefore,it is essential to coordinate theory and
practice.As Mark said,it is very controversial to find a suitable human/Pilot.

this Bing carb. are standard carbs on Rotax 912 Engines (very successful!!)
They are also
used on BMW motorcycles.
Beside my Kr ,I restored a Pelican Ul with a Global half VW engine and
replaced the old Stromberg cadb. and mounted a Bing carb. Works fine !

- Even a miracle needs more time!
I built mine from scratch,nearly finished- appr. 2300 hours +.
I think with prefab. parts ( it depends how many of them) it could be done in
650 to 1000 hours.

...I made a very simple calculation :
1100 rpm's comply with about 52 mp/h,when you use a 54 inch Prop.I supose, your
approaching speed on short final is about 25-30 more. That means, with the
powersetting you use at the final,the prop does'nt produce thrust,he'll brake
you.

...the reason way I plan to install VG's on my Kr is to prevent loosing aileron
effectivety in some worse flying situations. For example,when you must handle
a forced landing after an enginefailure,or you approaching a short airfield
with a small pattern.I think it's always an adventure to

I will do that on my Kr in the area of the alerons toward the wingtips and
probably on the bottom of the HS.

when you make a weight calculation for the wings,I think it does'nt matter
what kind of airfoil you use for your kr .( I approve all thoughts of Mark
Langford's reply).A very important point is the choice of the wood what you use
for the spars, or the entire airframe.(you know that Sitka

When I have done the bodywork on my Kr I've got the best results by mixing
resin and micro ballons (no matter what epoxy-resin you use)at first, to a
