I have both the old version of the 80" Hangar 9 Cub ARF and the newer version as the PNP. The PNP came with an Evolution 46 that was very undependable. I sent it to Horizon for warranty repair as it is within the two year warranty. I am going to go with the Saito Fa 62 when I get the funds together. My old one has a Saito Fa 56 and it flies very scale- like. I think the 72 will be great just throttle back as the plane will be over powered.
