Bell407 Vs 350b2

[heliwolf]

As for a 2 bladed systems at altitude, i think an astar landed at 29000' and has climbed to 44000'.

 

WTF you really confused me, you are talking a two blade system, then talk about an Astar????

 

????? What Astar had a 2 blade system ?????

 

Sort of like comparing a Piston Engine to a Turbine, NO???? :prop:

"i think an astar landed at 29000'"

 

They put the toe of the skid on the top of Everest with no fuel and a pilot. Just an Eurocopter publicity stunt.

If it was so easy why doesn't Bell do it? :up:

 

Even in a low cost B or BA you can fly circles around any jetbuggy or longdog. I agree with WTF's money maker math! 2 trips DOES make more money than one....lol

[Over-Talk]

WTF wasn't saying an Astar had two blades. He was saying (in an ambiguous way) that some aircraft with multi-blade systems can do well at high altitude despite what Bubbles had said about how well two-bladed systems work at altitude.

 

A toe-in on the top of Everest may be a "publicity" stunt......but you have to admit it was a h*ll of a stunt which no other aircraft has done. It still says alot about the aircraft's great performance.

It was more than just a case of doing "whatever you want with horsepower".

 

Astars, L4s and 407s are all derivatives of old technology.....but they are still the leaders in the field......unless you want to go all the way back to Lamas!

It would be nice to see something new in the 5000 lb gross wt. category (and don't say 429!!!).

 

As always in the 407/Astar debate, there are different opinions for various reasons, which are all valid, but can't we discuss the differences without being unpleasant to each other?

There've been 8 pages with no bloodshed or violence threatened, hardly an insult thrown, just a couple of mistunderstandings causing irritation.

 

 

Good job people.

 

The 407 you have to put your collective elbow into the ribs of your passenger at the bottom of an auto after leveling the flare if you are taller than 5'8.

 

Would anyone agree?

[T-rex]

What about this?

 

What came first, the chicken or the egg?

 

Probably make the same progress as the last 8 pages...

What came first, the chicken or the egg?

 

the rooster...

Concerning the subject about the L-4 high altitude tailrotor being very heavy... A friend of mine just told me it's the elastomeric greaseless bearings that are causing it and that the newer style jetranger tailrotors of the same type are very heavy in cold weather as well.

 

This L-4 has fairly heavy pedals in the summer but it's definitely manageable and you can get used to it, but whoa baby... -40 C is another story. She gets hellishly stiff on the feet and vibrates some when the tailrotor is flapping. I'm not a big fan.

Flew 35 hrs last week in our L4 with standard tailrotor and still feel like a cripple today...put some boost on that thing...please

[skullcap]

As don't know anything bout L4 I ask if it has similar t/r pitchchange as jet ranger. As a jetranger in cold temps if has too much grease in boot will cause extremely heavy loads. If you ask nicely of your AME to clean it out and just put in a small about of grease helps tremendously. Often wondered if Tannis kit which heats t/r gearbox helps this.
