I used to fly an AA5A G-BFIJ, 160hp and long range tanks, which was very comfortable for long 4 hour flights. Very good performance at 2400rpm/115kts. Very good visability and a really clear panel. I was told by a maintenance organisation at Biggin that in fact they are very cheap to maintain. I like the way the cowlings open and the slide back canopy that is safe and great for taxying in hot weather. I think the AA5B with the 180hp is slightly better at load and speed, but does used more fuel. If you are looking for a LAA type, but only two seats then you cannot beat the simplicity of the RV6/7 or the 4/8 if you want tandem seating. All of them will cruise at 130 - 150kts.
