I bought 4 sheets of 20" x 30" Elmer's acid free foam board from my local Walmart, without knowing that it is quite heavy. I had an ambition to build the
Flite test Fokker DR1 as my first foamie… well that was a mistake. Yesterday I test fit the three wings with the assembled fuselage (it's all scratch built)
It's way too heavy. I don't think it will get off the ground with the power pack F I ordered, so I'm going to chalk it up to practice and look for a new build. I don't have a precise scale handy but it's at least 1.5 lbs without the landing gear and electronics not to mention the battery.
I don't mind at all, it was important to practice scaling, cutting, beveling, etc some things I had never done before - but this thing is never going to fly.
I think you have to buy 25 sheets at a time though. I have three dollar tree stores near me; none of them have a box opened on the floor. It's not the cost that I'm averse to it's the space, I wouldn't even know where to put the other 20-23 sheets until I need to use them
