Just for comparison, I have a friend here with a tidy classic KR2 with the original retracts. It has a Revmaster 2100 on it rated at 75HP (maybe at 4200rpm, but max rpm on T/O is 3300 rpm, so probably 55hp) Basic weight is 625# at the moment and with full fuel (95#) and Pilot(145#) his usual MMTOW is a smidge under 900#. He has the older aerofoil too so I think this is quite representative of that model. I didn't get his fuel burn but I remember doing an exercise converting the 55HP back to FF using BSFC and it worked out to be close to what would be expected, around 4G/H. At 25'C he can climb at 900'/m and normal cruise 138m/h.(120kts). Paul.

I know a guy who must be only 165lb. I can only confer with what I know, which is my Jabiru 2.2 Kr2, 75 hp. It drinks 26 litres at full power 6.5 us. My best cruise figures are at 18 litres 4.5 us per hour, so my cruise is still actually quite high at around 70%, at 120 mph. My kr only weighs 540 lb empty due mostly to the light engine and no flaps or speed brakes or interior trim . All take off performance figures are at max gross anyway, well in my book and every other certified aircraft book they are. So at 900 lb (published MAUW)
