I have one of these under construction just for fun. I plan on flying it to warm up for the 1/4 scale ww1 warbirds I fly. Was considering using a .52 4stroke I have but this sounds like a poor choice. I have converted to ailerons with tail wheel and plan a candy drop hatch. Looking at the 4 stroke weights OS has a new .70 4s that lists a weight of 18.3 oz. Magnum lists a weight of 21.2 oz for their 70 and a weight of 22.4 oz for the .90 4 stroke. I would rather own the larger 4 stroke if I am going to need the nose weight.
Any thoughts?
