I currently fly a KF5 and love it, That being said, I Changed the Elevevator to the 7, Put on Wide Bush Gear with larger tires, Changed some of the Instrument Panel, Put on an Alaska Bush Tail Wheel. Put on VG's, added a Heater. etc, etc, etc. and I fly it Conventional and wouldn't desire to fly it as a nose wheel plane where I like to fly.

That all being said I still would like to add the 7 engine mount and change the cowling. So If you have a chance to buy a 7 or SLSA I would go that route, You can convert from Tri to Tail wheel when you like, have all the benefits of the items I had to change and you already have the better CG with the 7 engine mounts.

No don't get me wrong, I love my 5 and it does everything I want to do, but I had to make the changes to get it there from a stock 5 to get what I wanted and still would change a few things, The 7 or SLSA is ready to go.
