How 'bout this diesel powered C/L'er. It's an Australian Aero-Flyte Mustang Trainer replica I built recently. My brother and I used to fly one just like it on a tennis court in the early 60's. Thats a 45 Y.O. Taipan 0.9 up front. Very small tank, still runs for about 6 minutes, which is more than enough time on 35' lines.............John
