Default Where's the CG on the Cermark .40 F-20?

I bought this plane used, so I don't have the plans or instruction manual. I noticed all the radio gear goes in the back. Does anyone have info on the CG location? This isn't the .60 ARF, but rather the .40 kit. Also, what engine did you power yours with? Thanks.

Default Cermark .40 F-20

I have the .60, and the .40 .
My .40 has a Rossi .45 long-pipe in it, and "hauls"...but no retracts.
I had to mount a regular 4-cell flat-pack in the extreme rear or the plane....flat up against the rear bulkhead.

"The optimum CG is 4 1/2" from the leading edge at the start of the wing saddle." (right out of the manual)
