You do raise a good point,some planes just dont benefit from light engines,as they need all the weight up front.
But you are telling me,if I built this one with an OS 120,I would have to add one full pound of of lead or whatever to the firewall to get a CG?
I have build 60 aircraft,some needed a few ounces here and there,but a full pound of weight in the nose is something I would argue to be completely incorrect. As stated I dont own it,and cant make definate statement.
