Matt Chapman Eagle 580/4 /Stroke Engine
I have the Matt Capman ARF that I want to put a Magnum XL52 on. I'm not sure if this engine will be strong enough to really perform as expect. Do you think I should upgrade it to the Magnum 70 or 91? Also I have an old O.S. 91 sitting on the shelf collecting dust, but that may be to big for this plane.
Thanks,
