Saito 1.25 will fly it fine. I have had a Saito 1.80 in my first one then went to the zenoah g-23 was so much more fun and cheaper to fly with the zenoah. The evo 26 is awesome since its real light and more power then the zenoah. The Saito 1.25 will be a blast with it too have fun with it they are nice flying planes.

The 120 ax is a really nice fit. Vertical is maybe not unlimited but sure is close. Today was my first flight and all was good until the motor died due to losing tank pressure. The muffler had been in a prior nose over and broke both stingers. They were JB welded back and that was where I made the mistake to use it. The stingers came loose in flight thus the tank pressure issue. I had no chance of getting in back to the runway so I landed in a field nearby. Fortunately the only damage was to the landing gear. The ply that the landing gear is mounted to is unbelievably light. It needs to be beefed up before anyone attempts to fly the Cermark.

Howdy all.
I just picked up a perfect shape blue version at our club swap meet.
Can someone give me the forward and aft balance limits?

Thanks!

Okay I lust looked at my instructions to see what it says. It says to balance it 1/4 inch in front of the rear cabane strut. There is a nice picture in the manual that shows this. I do not want to assume you don't know but because I would not know without the picture I will explain better. The Strut/frame work that bolts to the center of the upper wing is the cabane strut securing the wing with 2 bolts. The rear most bolt goes though this rear strut. At the leading edge of that rear strut measur 1/4 inch forward and balance there.

Well in an effort to over do everything I picked up a new OS 1.60 fx with a Pitts muffler for my Cermark Pitts. Should be somewhere between balistic and rediculous

Mr67Stang,
thanks. I also saw on another post that 1/4 inch in front to the lower wing. I need to go look at hot the rear cabane lines up with leafing edge of lower wing at the fuse side.

As far as the OS160 and Pitts muffler, the guy I picked up my Pitts from started with one in his and needed 12 oz of lead in the tail to get it to balance.

It will fly it fine its lighter then the g-23 and almost the same hp. If you own the engine all ready I would say use it if considering and gonna buy a engine I would go with the evo 26 lot lighter and more power.

I think You misunderstood me so I took a picture of the balance procedure.

18 X 8 APC but think I might switch to a 16 X 8

This was plenty of engine for a little Bipe . Def requires a new set of skills to fly but its a blast.

Keep an eye on those little 440 bolts that hold the metal wing connector brackets to the fuse. They loosened up from vibration when I was breaking in the engine. The are a royal pain in the a$$ to tighten.
