My MVVS1.6 hovers my fat (12lbs) 24% CA Extra300L at full throttle, Menz s 17x8, 8100RPM. That's the best prop to practice IMAC. I have unlimited vertical with Menz S 18x6 at 7900RPM and 3D stuff.
I am using an incowl Bisson Pitt muffler.
My flying buddy is flying a light CaP- 232 at 10-11 lbs, 72'' and OS160FX. He has unlimited vertical at half throttle. He flies 3 flights and come back to home, 1/2 gallon glow burned. He broke the fuse last weekend in two parts. That's the cost for overpowered plane...
I fly 10 flight, cost nothing of gaz!
Ask me if i want an OS160FX? No way man!
