Hi Dan You may be able to deduce from my spreadsheet, Weights and Balance Excel Document 1 - Latest data on certified scales, that I stay in the front 6.45 inches of the C of G range (I was aiming for the front 6 inches).
I achieved this by having the most forward configuration (full fuel plus 80 kg pilot) at the very front of the C of G range. My worst case scenario is fully loaded (122kg passenger plus 16 kg baggage plus me) with minimum fuel. I have flown my KR2 configured as such, though I had 14 litres of fuel on which gave me a C of G 6.16 inches. I have never loaded the KR2 like this since testing, maximum loading for normal operations does not have a C of G of greater than 4.2 inches which is myself plus 100kg passenger and no baggage. 95 percent of the time there is just me plus 5kg of baggage so TOW is 366kg (808lbs) and C of G of 1.3 inches.

This will be very helpful. I keep coming up with quite a bit longer mount for the KR2s. That may be because of the extra length fuselage. From reading through the forum on a search of cg, I am led to believe that the real cg range is more like 8" behind leading edge to 13.5" behind leading edge, so makes for a long engine mount on mine. I am still working on thinking this through so really appreciate your input. Dan
