Well your not going to fit a strecher in the 66 either. Hpw long is the floor space front to back. Enstrom make a stretcher kit for the 480

Old article, but this shows one concept for 505 in EMS configuration:

And anyway, with its L-4 drivetrain and 504 horsepower engine,
L4 drive train? Really? According to Bell reps at Heli Expo, Bell ditched the L4 nodal beam transmission mount for a less costly approach. I am hearing persistent rumors that the ride in the 505 is not exactly "smooth" as a result. When I questioned Bell about this, they said if one doesnt like the ride of the base 505, they offer a Frahm damper option which mounts between the front seats and weighs "about 25 pounds."

Bell rep also quoted a delivery date for an order placed now as "2019."

Did I misunderstand what you meant by "L4 drive train"?

My first close up look at the 505 was at Heli Expo this year and, overall, I was quite impressed. Lots of value for the money IMHO. Cant help but wonder how long initial pricing will hold.

Yes you did not understand. The nodal beam is not part of the drivetrain. It is the pylon support or basically part of the airframe.

As to vibration suppression Bell's attempt to have no nodal beam to reduce cost resulted in unacceptable vibration. To correct this Bell installed a liquid vibration reduction system on production models which is similar to a nodal beam in purpose. The Frahm is a standard device to reduce vibration further if desired and can be found along with active hammers on 429's, 350s, 76's, 92's etc.

Got it. I was interpreting "L4 drivetrain" in the broadest sense. I am familiar with the Frahm damper as a result of flying the B407 for awhile. Smooth, fast, quiet (relatively speaking)! My standard of reference for a light single helo. If the 505 comes anywhere close in terms of ride quality, likely to be a big winner for Bell.

The 505 probably has more in common with a 47J than an L4.

Had a look at one at HAI in Dallas and in all honesty it looks crude.

So much for an elegant and simple solution.

I think the cab section is made in Spain.

It looked to be about as elegant as an R22. Lots of screws everywhere.

Tubular frame - cables to the TR control.

I doubt that it will be as durable as a 206.

Time will tell.

The fuel line looks horrible. I would re-route that straight away.

You guys are looking at the marketing mockup. Production bird looks completely diffferent back there, notice that the transmission mounting system doesn't look like the fluid damper version in the production design
