Many thanks 'Discorde' - hadn't seen that one before. The performance figures quoted seem pretty fair, and if you want to get anywhere with reasonable alacrity (like when I ferried mine from deepest Kent up to North Aberdeenshire) then setting 2400/ 24" and sensible leaning will produce at least 110kts TAS at 2000ft , for about 45lts p.h. The way I'm operating it right now with lots of circuit work burns more like 50lts. Using a 500 metre hard runway is pretty tight for it, and requires 50-55kt approach to ensure bringing it to halt - even with brakes ! So heavy, it just keeps on rolling, even lightly loaded.... The article rightly suggests 60kt would be better for a more predictable round-out, but beggars can't be choosers.
