I fly at around 3K feet and a 140 is the most i would put in this plane. ... Lets me fly it like I stole it, and landings slow down ok, but i'm using almost 90deg flaps. 90 del vertical accelerating take offs with full fuel too .. , and I rarely ever go full throttle. the plane is too delicate ( when compared to something like an Ultra Flash, or Bolt)
Just my opinion, and i'm usually one to severely over power everything and any thing 😁
