I must say that the GWS set up by Daniel is great for planes in the 12-14 oz weight category. I found that the ST Model power plant (370 turbo motor) with a 11x5 prop (3S1P batt) is amazing for a cheap brushed unit. It can haul my GP Micro Whizz (16 oz) with nice verticals. I hate to say this but after flying a lot of foamies, I am leaning more towards balsa planes. They seem to fly better.
