Just an observation on my part. Would like to hear your thoughts. I am an average sport flier who enjoys building as much as flying and I like to customize or kit bash everything I work on and always use light-weight construction methods to ' keep the weight down', as we all like to do. My planes fly great and suit my flying style; realistic flight and realistic aerobatics, no 3-D(umb). Something really neat happened this winter when I added floats to my clipped-wing Venture 60 for flying at the lake. Imagine bolting 2-3 POUNDS to your 60 size flier and scooting around the pattern, rolling, looping, stall turning, etc, etc and landing like a feather. I did not even touch the trims as they were set for land based flying. As a bonus, the plane penetrated the 15-20 mph breeze better than without the added weight. Now, I am not suggesting that one shouldn't pay attention to keeping things light, just don't sweat the nit picking stuff and go enjoy yourself. Your thoughts?
