There was no F-27. But great list anyway.

Confusing. But I can clear it up... it was the prototype constructed from the 280FX airframe which had a strict seating of 4. Further design studies allowed the installation of a fifth seat into the production designs, I believe in a 2-by-3 layout.

Silly me.

By the way, here is a diagram showing some of the 480 series seating arrangements.

I have some to add to your list:

Enstrom Model-800 --- five-seat helicopter project with two Allison engines,

VIKI --- coaxial-rotor version, not sure if it was just a prototype or kit-mod, or an officially modified variant.

Whoa.... I didn't expect this thread to fill up so fast! Thanks for all the cool stuff. I've added those other ones to the list.

Thanks Gunship, for the photo of the F-27. Never knew about this one, but it now seems that the first prototype had the 2-bladed rotor and a steel tube tail section and was known as the F-27, while the other 2 prototypes got the later standard 3-blade rotor and the fatter closed tail section (F-28).
Learning every day.
Regards, Walter

None, it was a private modification who'se owner died back in 2000. Engine is an Allison, it also has Hughes Model 500 avionics and hydraulic controlled cyclic column. The rotor system was a Gyrodyne, believe it or not.

It was really working, but I don't think it was ever flown.

Hi HannetonIII, here is the Spitfire Mk. 1.

Pepper · Veteran Member - Level 3

No, what you have there is the Mk.2, second prototype.

Rudy Enstrom did some earlier homebuilt work too. Here's one of his designs from 1957:

Enstrom helicopters date that far back? O_o

And the VIKI model looks awsome. Shame it wasn't flown. cry

The recent TH-180 isn't here (the one that crashed)

280FX (also called "Shark", or is this a mistake?) - updated Model 280F

Being called that on Enstrom's official website should answer that question.

The 480B was developed to meet New Training Helicopter (NTH) requirements for the Army to replace the UH-1 trainers at Rucker. Eurocopter AS.350 and Schweizer 269D competed too but the Bell 206B-3 was selected in 1993 (became the TH-67. 480B-G is equipped with the Garmin G1000H all-glass avionics suite.

Hi,

as I said before;

F-27 was a three seat light civil helicopter;

Should I take the liberty of editing Hanneton's list in light of new information? He has a habit of disappearing for a long time thus prolonging these obsolete postings without updates. I'm a bit torn. :P

Stingray · Administrator

He consented to it before so go ahead.

N1135 was a trainer , designed by an ex-employee at Enstrom , it has a standard swash plate and fly weights and paddles to reduce control forces, no doors as the body slides forward to exit, it was bought by a guy who contacted me for advise on it's rebuild (it had been sitting out too long) I told him to keep it stock. but he thinks he knows better...to bad, It could of been a goodie. It was a one off design.
