I'm going to order Radical G30.
Im wondering which engine to choose from this 3 zenoah's:
1. G231 (http://www.centuryheli.com/products...html?pageid=332)
2. G26 (http://www.centuryheli.com/products...html?pageid=330)
3. G29 (http://www.centuryheli.com/products...html?pageid=323)

What u guys say? Which one to choose? I'm flying for 1 year, and not going to fly 3D with this (but who knows....)

Which one of this 3 engines will be optimal? More durable.
More power it's better but in case that i'll choose the g29 and fly in normal, will it be less loaded than g231, and by this - it will be more durable?

I prefer the G26 best. More power than the 231 and likes to rev higher than the G29.

Rev means revolution per minute (RPM), how fast the engine will turn. The G26 is very flexible, it runs well at low RPM's and high RPM's.

All of the Zenoah gas engines are very durable running 100 hours or more before needing servicing

A gallon is good for what? About 3 to 4 hours of flight time,depending on the displacement? That's 25 to 30 gallons of fuel! That's a lot of flying!

Yes gas engines are much more durable than nitro engines.

What makes them good for pilots that like to fly often is the engine durability and low fuel cost.

The gas mileage does vary greatly depending on head speed and engine RPM. I would never see 3-4 hours from a gallon of fuel, but it is cheap enough that it is not an issue.

one more question, about blades.
In manual is:
Main: 690-720mm
Tail: 95mm

I would like to buy assymetrical. What u'll say about that choice:

Main: Spinblades 710mm
Tail: Spinplades 95mm

Is the 95mm enough? Maybe i should but 105's??

If you can clear them

The 105mm will be better than 95mm tail blades. By clear I mean not sure if your model can handle 105mm without the 710mm mains touching the tails during 3D flight.

Each pilot likes different blade size, types and brands. On the Radikal, I used the 690's so clearing 105's would not be any problem. The RotorTech 690's sold by Century are very nice blades if you are alreay paying shipping for the HWC from the USA.

I need assymetrical for normal flights so far.
But i'll left 95 on tail for safety and 710 main.
Thx again ;D

Most pilots use symmetrical for all types of flying

G30

I had a Hanson Mod, G26 and Edge 693 FBL and Edge 105 and a Align FBL head on it and It had a ton of power, the reason I had a Align head on it because I could not get parts for the Century head at the time, they had just came out with it and I crash mine(my fault), good helicopter. Bobby

So I'll choose symetrical - easier to do autorotation, no need extended flight time - because gas heli flight costs are very low...
thx for tips
