As found in the Piston Pilot Training guide:
Also how do you secure the main rotor if you have to leave it on the ramp for a couple days?
Enstroms are relatively quiet helicopters due to the installation of the turbocharger,
and the slow turning main and tail rotors. They can be equipped with an
optional secondary muffler that lowers the noise signature significantly.and the slow turning main and tail rotors. They can be equipped with an

Finally delivered
My 280C was finally delivered today. First time I was in the pilot's seat and noticed a large gap at the bottom of the door. I don't recall anyone on here complaining about poor fitting doors. Is this a common issue and if so has anyone been able to re-fit the doors so they seal around the edges. I know it is difficult to have these thin fiberglass panels retain their shape so I assume this is a known issue. I am interested in your replies.

In the 28's the door has no fiberglass at all, it is just plexiglass. The last time I looked at a 280 the doors appeared to be constructed the same way. Mine were a little loose, so I used Home Depot weather strip which worked just fine.

The right door on my 280c had a big gap at the bottom as well.... Fairly common I see... Be ready for it to pop open at about 105 mph indicated.... It'll scare ya the first few times!

The small gap at the bottom is to let the water out from the leak at the top in rain!:
Plus the doors pop open as you near VNE to help slow you down.
All these features come at no extra charge.
ps just don't put maps between seats and doors unless no longer required.

It's just like driving a Land Rover - make sure you have a knee length rain coat so you don't get out with soaking wet trousers!
P.S. I know nothing about driving trabants! I was referring to Solihull's best but seem to have been auto edited!

I just noticed: I think what caused the door warping was the addition of neumatic actuators, installed in 2008. Too much force continually being applied outward on the flexible material without a latch at that point. Not a good thing unless the entire bottom of the door would have been reinforced with rigid material. Whoever came up with that STC should have known better. I've got another question for those in the know. Is there a throttle friction knob on the 1977 280C? The knurled knob below the throttle doesn't budge.
Therefore, to write Land-Rover .. one must insert a hyphen between the Land and the Rover!

I took a closer look at the knurled collar. It appears to be riveted from the inside of the collar to the chrome shaft. Does the shaft turn with the collar? To loosen the throttle is the collar turned to the left or in other words the top to the outside? Does anyone have a picture of a 1977 vintage collective on a 280C showing what the throttle friction collar is suppose to look like? This may have been altered some time. I just got around to reading all the logs on this ship, I know --dumb-- before buying, but I trusted the owner and mechanic. In 6,900 hours there has been lots of things replaced, upgraded, or added to her.

Thank you. That's what mine looks like and I got a confirmation from Roger Sharkey that it is a friction adjustment. Question is which way does it turn to loosen. I assume it is in the direction of the top towards you when standing outside or same direction as throttle increase? Roger told me to put a strap wrench on it and free it up. I think the previous owner just left it where it was when he go it and got use to it. The current feeling on the throttle is when applying force to the throttle it all of a sudden breaks and turns a little bit more than you would want. No way could anyone get precise throttle position as it is. I think that is why I am constantly fighting too much or too little adjustment when raising or lowering collective. Hopefully I can loosen it up a bit and still be able to tighten it if I wish.

lvflyer,
Don't put a strap wrench on it. Get an A&P to take a look at the friction mechanism. It's probably a case of corrosion, and if that mechanism is frozen solid who knows what else in that collective is corroded as well. I would not trifle with it.
Sounds like your ship needs a good inspection, and some corrective and preventive maintenance.
