Can anyone give me the distance from The leading edge of bottom wing of the cg of this plane, annoyingly ive scrapped the plans as they were damaged, also not been able to check against plans but it looks like the top wing has couple degrees neg incedence compared to bottom wing, ive built biplanes like this before, just wanted to check this is standard on this model and that ive not done it accidentaly through bad soldering of cabanes ..........
