On the Century site, the Predator Carbon Gasser SE W/Z260HP Engine is the Pred w/ the Hanson 26? Or is it a normal 26?

so the one in that option I metioned above is modded, but not the pro version...do I have this right?

The pro version is selected by itself?

Yes one is the 3D max and the other is the Pro.Century is selling the G26 pro mod. You have to get the 3D max from hansen. They also sell the stock G26.But it vibrates realy bad. It is not balanced.

They better NOT !!

No, the sales staff there is NOT allowed to sell a stock unmodified G-26 puh.

Personal preference is the stock 231.

I've been talking to Bruce Hason and he has a new motor coming out next month. He has it in a predator but as of last week it hasen't flown due to wind but he might have flown it this week.
its another g26, new double bearing crank, new piston.
he said the Smoothest one yet.
He said 2 more HP.
You should call him.

I've got a bird with a double main gear that might hold on to that much power!!

'Course a STOCK G26 makes plenty of power by itself!!

How much horsepower would you say a stock G26 makes?

Chris, instead of doubling up on the main gear to handle the power, why don't you come up with a damper in the single height main gear with 20º compliance (on the main gear) to take up the power pulses of the motor ?

That way, the main gear doesn't have to handle the peak torque pulses of the motor and vibration will be less.

Well, 2 reasons really, no 3 reasons,

It's simple,

It works,

It required very little in the way of redesigning something that's more complicated.

Well, it let you handle the power but it didn't help the vibration problem.
More power, more vibration.

We don't seem to have the vibration problem so why fix something that ain't broke??

My Turbine has a LOT more power, but I don't see any discernable vibration!! Neither does the Industrial Twin.

Wanna try that equation again?

Are you really trying to equate the power output/vibration of a turbine to a one 110º power pulse per revolution internal combustion engine ?? Really ?? In your position ?? As a manufacturer ?? Really ?? Let alone the natural vibration that all 2-strokes have from the counteballance weight of the crankshaft ?? Really ??

Not at all, I'm replying to your statement, and I quote "More power, more vibration"

Her we go again. . . .

At that time we were talking about internal combustion ONLY.
THEN you brought up the turbine . . . which brings my question !

I wasn't expecting you, as a manufacturer, to be confused by that.

Fine, forget the turbine, Might check this by the way http://en.wikipedia.org/wiki/Internal_combustion_engine

Wanna try the Industrial Twin then? It's a 2 stroke gas powered engine with more power and less vibration.

Oh wait, we're only talking singles here, OK, I reiterate, we don't seem to have the vibration problem, why fix what ain't broke?

Good save, yes a turbine is IC . . . . But I don't believe anyone else has any confusion about the vibration levels of a turbine compared to a recipricating engine.

An oposed twin can eleminate the lateral vibrations but it still has the tortional vibrations just like a single because it still fires both cylinders at the same time. Which is what I was getting at with the dampened main gear.

Well, again, vibrations aren't a problem, in my birds, why make it more complex. (One caveat of course are the mistuned engines, then even a dampened main gear won't help!)

A good idea is just that, a good idea. Since I don't see the need for it, why don't you build it and market it.

Vibration is ALWAYS a problem, sooner or later. Simply calling it a non-problem does not make it go away.

I will do that. But my solution is quite a bit different. It's in the works.

Will a perfectly balanced 2 stroke engine still vibrate?
