IO540
I would have thought that the cost of fuel on “conventional” machines such as the TB20 would have had an impact on the second hand value. Most UK pilots are VFR only and there are much less expensive ways of touring VFR which were not available 5 – 6 years ago.
I sold my AA5B 4 years ago for about £43k, but it is now unsold and advertised at £32k in very similar state to when I sold it. On the other hand Rotax 912 powered kit is selling in large numbers, and with new 912 kit selling for less than 100k, the old tec aircraft are suffering.
