My last KR just had foam with glass over it and the wing ends got a lot of hanger rash that 3/32 ply would have prevented.

If you have a look at the pictures in the construction manual ( pictures N0 3, 26, 27, 28, 30, 31) they clearly show plywood ribs with large lightening holes at each end of the center section, and at the inboard side of the outer wing sections. On the other hand, drawing N0 68 page 79 shows no plywood rib anywhere near the WAFs; and it shows a 1"foam rib at the inboard side of the outer wing section. Confusing.

I used two 48" ribs on each side in the center section as sanding guides and a ply rib on each end of the outer wing panel for a sanding guide.

After several false starts it finally all came together. The weather was perfect, nil wind and silky smooth air. The take off was a little jerky but I soon settle down to 90kts for the climb out. I climbed through very broken early morning cloud at 3500ft to 4500ft all my temps were good, CHT 50F below maximum. A few turns straight an level then power off and simulate an approach 2000ft above the strip, round out to stall, felt soooooo good. Now descend and join circuit, the water on the near by lake was like a sheet of glass, not a breath of wind. Lined up perfectly. I read somewhere that your first landing will be your best and they are so right, I greased it on like I'd been doing all my life. Back to the hanger and my wife. I went over all the suspension bolts, engine mounts, prop bolts and anything else that I could check. All was OK so back out to the strip and out for a short circuit, a small bounce on the next landing and a very long roll out, back track and take off again. The next approach was way to hot and at half strip I went to full power went round , this time a much longer approach and I notice about 5kts wind at 60 degrees to the strip. This was a rough old landing with several small bounce. So back to the hanger (and the wife) and another though check over. Half an hour air time in total. Yeeeeeeeee Haaaaaaaaah and grin that will have to be surgically removed, if at all possible. I have to wash the bottom of the aircraft as I'm operating from a grass strip and the early morning dew covers the bottom with water and grass, etc. This morning, 29th Dec 2004, I woke well before sun up, Doh. Out to strip, pre flight the KR2, perfect weather. A quick circuit with a near perfect landing (not as good as the first one), back track and take off again heading for our ceiling height of 6500ft. Now for some stats. Engine is a 2.2L Jabiru 4 cylinder - total engine time only 1.3 hours on the ground, engine red line at 3300 RPM Prop is a Richard Sweetapple 56 X 56 timber prop Static RPM is 2800 Initially max RPM was 2900, very tight motor. By 2.7 hours max RPM had increased to 3000. Best climb is 980ft/min at 80kts but the CHT's are climbing. Ideal climb is about 750ft/min at 100kts, Oil temp of 100C and CHT temp of 290F Cruise at 115kts no wheel spats or cover strips and still 2 big holes where the retract gear came from. 6 touch and goes and then run low on fuel, all not to bad. Only 40 Litres capacity and I was down to 15L so back to the hanger and another check all over. I cann't get refueled to this afternoon. :-( Next flight is planned for tomorrow (or maybe late this afternoon).

That might work, but I am running out of room on the firewall. I was thinking of screwing them to the back of the Diehl case if I could see a pic of that. Another option that someone sent me is to hang them from the motor mount.
