Thanks for the replies everyone. Good to know about the ac. I guess I'm just used to my Cherokee which doesn't have much ventilation on the ground and doesn't climb like an RV so usually pretty hot in flight as well.
I guess I'll have to try and sit in a few 7s to get a real feel. Thanks for the offer of assistance Martin. I'll let you know.
As for the 14, I would love to but the kit is about 10 grand more (u.s. $$$) and the engine they talk about is pricey as well... (the CinC watches the finances quite tightly!). Anyhow I'm just starting to ask questions as I still have 5-6 years before my Cherokee is due for engine OH so I have time. I'll keep everyone posted.
Keep the great info coming!
