Hi

I got a midwinged plan from a friend who got it as payment for a job. After finish building it I have problem to find were the CG shall be. What I have done is that 1/3 of the wing is balanced with everything in it except fuel. On the maiden fly it wanted about 5 degrees of up elevator. After some reading I try flying inverted and found that I needed down elevator. Applied 10g of lead on the tail with no success after applying 40g more it started to be better but now it wants to go up if I reduce power. This thing is starting to drive me nuts but I hope that some one out there can help me.

Regards
