I worked for OFT for a while, but as a Heli CFI, i recon you wanna go for the fixedwing stuff, right?
OFT is pretty busy when it comes to fixedwing, they have plenty of instructors, even good instructors from Europe (mostly Norway).
Plenty of planes, range from stone old 152s to brandnew 172s with glass cockpit. They also have a few multis (Seminoles and a Duchess) and a couple of Piper singles.
ATC in Kissimmee is very patient, because they are used to (foreign)students.
At the moment there are at least 70% Indian students, so bring your dictionary.
A couple of small uncontrolled airports in the area, which comes handy for the early training, but also the Orlando Class B overlaying, which is good for instrument training and general radio communication training.
The appartments are crap, there is no other way to describe that, but there is a lot of action around Kissimmee/Orlando. (Disney, Bars, Malls etc.) Shuttle launch in Titusville is a great thing to see. BUT, Kissimmee is as far away from any Beach in Florida as it gets. (Bummer, because the weather is NICE)
NAC is definetly the nicer place to live, but i can't tell you about the school, i visited them, but i don't know about the training.
I have no idea who EFT or OBA are. But you might wanna look into Hillsboro Aviation Oregon, that would be my recommondation.
Well, i hope i could help you
Take care.....
