Plane identification?

Not sure if this is the right place for this but... I'm new to the forums and only been around rc planes for about 2 years. I bought this plane last year, and I'm just now getting around to flying it. I have little info from the previous owner as he bought it from another guy etc,etc.
I believe it's a .40 size plane, but it had been converted to electric. It has a wing span of 56inches and is about 42 long. It is an older plane for sure but I haven't found anything in catalogs or such that has anywhere close the body lines. As you can see the wing tips is rounded but the front fuselage is very boxy looking. Any help would be great! I need to find the CG for this model as I'm not sure if the guy that converted it to electric has it anywhere close. Thanks in advance.

Very cool looking plane, looks a little like a Shoestring C/L plane but the cowl and canopy are different. I would balance it on the main spar ie. 1/3 of the wing cord, and go from there.

you can find the CG by locating the average wing chord and let the cg like 28% of that spot back from the leading edge. To find the average chord just measre the root chord and the tip chord and add them. Then divide by 2 = ave. chord. Locate the line where the ave chord is on the wing. You can also just draw a line from the front center rib to the trailing tip and the leading tip edge to the center rib rear. The spot where the two lines intersect should be your mean average chord. Take the length of yur MAC and multiply by 28% (.28) and measure that distance back from the LE at the MAC. This will get you in the ball park. Trainers usually balance 30-35% The more aerobatic/scale planes are like 25 -30%.

It reminds of a WorldModels Rambler 30. Thats a decently close guess I think.

Well I converted it back to glow power, I had Saito Fa65 4 stroke that looks mean on it. The only draw back is it won't fit under the cowl. I have had it up about 4 times now and it flies awesome.
