I've just dusted off my C140 and taken it for a few twirls since layup last summer.
Since then Ive been flying a YT Adrenaline and an EF 68" Yak.

Flying all three on the same day leads me to the following impressions:
Adrenaline 3rd place (I've a heavy 140 engine upfront) good all round performance, can stall and catch the unaware.
Yak 2nd place, excellent all round performance.
C140 1st by a considerable margin. Flys light and presents well. Never looks laboured. It may not look that pretty but it flys better than anything I have touched. Expensive to run though, 8 gallons of MT Yamada20/20 please.. ouch...

Aside: after three flights I snapped a rudder cable so when I got home I thought I'd check the model over. The engine box/ former F1 (engine box attaches to this) was coming away from the fuse. Another few flights and I reckon the YS would have had the front pulled off. Watch for this.
