Default The Rivet riseth!! :) and a few questions

Hey guys, after many years not flying im going back through all my planes and fixing them up in anticipation of spring here in Aus (still pissing down rain and windy )

Stuck on my rivet at the moment. It was one of Vicman's kits converted to E-power (I know, blasphemy).
It seems Ive kept every other plan to any aircraft I've owned but not this one. Does anyone know how far back the COG is from the leading edge at the center of the wing? And, any idea on the throws for Aileron and Elevator??

Attached is a pic in its current state.

I've had to rebuild pretty much the entire nose after it nosing in at relatively high speed when the vertical stab snapped of in a rather aggressive 90 degree turn (was not reinforced at the join with turtle deck, is now!!!) In my first attempt to rebuild it I had pieced together the original parts but it came out not very straight, actually more wavy than anything with the firewall about 10-12 degrees off square (was a great learning process though). So i just cut the front off with a hacksaw and now have a nice straight plane!!!!

1/2a Rivets Build!
Here it is when I first built it a few years ago

Furthermore, does anyone have a copy of these plans (digital) to future proof me in a similar situation (I have the .02 rivet half plans pdf) but I would love to scratch build another one from vicmans plans if at all possible. Was so simple and such a fun plane to fly.

Thanks in advance for any help I might receive from

Damo.....you could try the old standby which is one third of the way back on the root rib. In other words.....if the root rib is 9 inches long put the CG 3 inches back from the the leading edge.

If Vic's plane is a sized up model of Kampen's .020 Rivets and you have those plans, my inclination would be to calculate the COG as a percentage of chord on the .020 Rivets and apply that percentage to Vic's plane.
