I spent my airplane time replacing the Balsa stringers with Bass stringers. Way in the heck better. I think it only added grams extra. Don't have a scale.
It was actually easy to get the Balsa stringers out. I did not even break one of them.
I also mounted the engine mount. This is going to be a side winder installation, engine on it's side. I did this to get the engine carb and the fuel tank to line up. If I had stretched the tank compartment 1/2" I might have been able to get the tank up high enough, but i didn't think of it. The back of the tank protrudes thru former #2.
But I also got a few minutes on my
Pacific Ace 74 today, painting frame work that the windshield and windows will leave exposed.
