I agree with making sure the CG is correct, however with the 1.60 this airplane will be grossly underpowere. That is a 50cc gasser airplane and the 1.60 glow engine has about the same power as a 30cc gas engine. 17 lbs is also a bit heavy for an airplane with just over 1,300 square inch wing but not too bad provided you have enough power behind it. IMO you should not even try flying it with the 1.60. I would strongly suggest you get a 50cc-55cc gasoline engine. I know this is not good news but my hope is that it will prevent you from bringing the airplane home in a bag.
