It does seem like a large plane but it is mostly due to the wing other than that its not much more than a bulky trainer so most agree it will fly then but avoid potential power demanding situations. I have a 12x8 prop on it now and it would pull my four star out of a hover (Gradually). It has good power and only has around 4 jugs of fuel through it so its fairly fresh, just dont want to be in a constant close to stall attitude. Made a little seat and pilot torso set up to go in too, will every ounce be critical , should i leave this out at least for the first few flights or am i overly concerned. This is going to fly circles and take off and land.
