Ultimate Bipes
I know you said kit, and I have seen other people suggest the Dave Patrick Ultimate, but I really do think you should at least consider the DP Ultimate. I have one with a siato150 and it is hands down the nicest plane I have ever flown.
Yes it is and arf and you will find things you dont like. For instance the firewall is very far forward and needs a little work to get the saito muffler on.
It is really light, around 10-10.5 lbs with the 150, thats about a 20oz/sqft wing loading.
Just my 2 cents.
