Great, keep us posted!
By the way, can you post pictures of your engine mount and where you did put the lead-stuff.
I tried to balance this bird yesterday with an ASP 61 4-stroke in the nose, and an arm going out from the firewall with the receiver-battery mounted on.
Still not even close to the recommended (3") CG [

Considering getting a larger engine.. the ASP 70 - 91 weights 200 grams more than the 61. But that means this beautiful plane will have to wait a while longer before getting airborne.
