Okay that makes me feel a lot better. I expect you will have a nice short flight in a local flying field. I have put a lot of effort to get a Guillow kit down to 86 grams for flight weight but I believe if you can do that, they will be very good flyers. I just put my Me109 on the scale and it is 79 grams. That is balanced but now without prop and rubber. That plane flew for 38 seconds and was enough to get my 3rd place in an FAC event. My new planes are just a bit lighter. My goal is 75 grams AUW.
My latest build, the Zero trainer is in the condition of yours... that is, not balanced and no prop and rubber... It weighs 60 grams!

And once again, very nice build and Good Flying!
