Hello All, Next month I'll start cutting wing spars for a KR2S, and now I'm doing my usual last-minute dithering between different options when I have to make important decisions. I'll have enough wood to construct 5048-15 airfoil spars. Since I might ultimately go with a smaller engine, I'm

I'll also bring some ramps that are perfect for those scales. I have two of them, anyway, and they are something like 1.5" thick. Another of those would be nice, along with something like a 24" stool for the tailwheel planes, although a cardboard box or two might get that job done. If

The Diehl wing ( longer wing ) weighs more than the stock KR2 wing. If you stand a stock KR wing up along a Diehl wing, it is like standing a KR1 wing up beside a KR2 wing. I am just estimating here, but if you got a stock KR2 wing, no tanks, fully painted, with counter balance, in at 45#, you

Thanks to those that responded to my question about weight. I tried the archives but I rarely have any luck finding what I am looking for. I don't know why as others get along just fine. My KR2S 0200 was heavy at 775 lbs. but since have added some instruments and several miles of wiring and

I'll add another thought to my earlier post. Adding horsepower for more speed is , again speaking in generalized terms, a loosing game. As your speed doubles, the drag is squared. To get the best performance from moderate horsepower, keep it light for low end performance and streamline the

Netters One more weight and balance question. Where should the CG be on an empty airplane? My KR2 plans say the CG envelope is 4" ahead of the aft side of the front spar to 4" behind it.By moving my battery and ELT as far back in the tail as I can, I come out right at the forward CG. When I

Hi Ralph, The empty CG is not relevant. The CG of the plane when loaded is the issue. If you have a header fuel tank then you want to be right on the forward limit with minimum pilot weight, no baggage and a full tank of fuel, the CG will move back as you burn fuel off. On the other hand if
