Hi Guys

I have YS 120 and Zenoah G-23 to install in Hangar 9 Edge 540.

In your opinion, witch will pull better?

Is this a good model for 3D and knife edge loop?

Thank you for help

I have the H9 Edge running RCS 1.40 at 12 lbs RTF. It does very well.

I would say definitly go with the 1.20 for now... the G-23
would barely lift it's own self bolted to the Edge.

Now....for 3D I would recommend the ZdZ 40...less weight than the g-23 and TWICE the cc's...about 25 lbs thrust.

If I had to do it all over again....defintly would bolt the ZdZ 40 to it.

But for now...keep it LIGHT as possible...with the 1.20. You will be happy with it...The G-23 is only good for more wing area like UltraStick at 1200 sq inches and Trainer types....

I've never seen a G-23 do 3D bolted to anything....Thrust to weight is just not there.

Hope this helps!

I would not recommend either engine for 3D. If you are going that route then I would recommend any of the 2.4 or 3.2 engines with electronic ignition.

I'll second that!!.......neither of those two choices

Anyone try a G-38 in this puppy?

3.2???? Thats nuts.
