Ive flown a Kitfox-7 across Southern Africa as well as a bit in the Savanna with John. Im very impressed by both! The Kitfox-7 is a designed as a tube & fabric taildragger and the Savanna an all metal nose wheeler. Both are fully closed in, have strong landing landing gear and capable of carrying a large load for a 2 seater and this is very important for a "Bush Plane".
Although maybe a bit off this topic, but I do think worth mentioning is 4 seaters, there are many choices in both the NTC and certified range. However I have noticed that many of the 4 seaters are underpowered. A bush plane should have more than sufficient power up front! Ive test flown Bundu Aviations Zeneth STOL 801, it performed well however in my opinion the 801 should have a 200-230hp engine. A 4 seater certified competitor for the 801 is definitely the old pre 1962 Cessna 182, 180 or 185.
With regards to certified 4 seaters my money is on Cessna! My 1962 C172 has no rear window or seats in the rear, it is a 2 seater most of the time with loads of available capacity for luggage and equipment. There are STOL kits, engine and prop mods available for these planes. Its also good to have an engine that can run on mogas.
