Gentlemen,
Thanks for all information . I don't care who is wrong or right but by sharing our experiences, knowledges and challenging each other, we do the most important thing,
WE LEARN!!
I have used the IMAC calculator (thanks erjpilot) and the formula (JimTrainor) and both give the same result of 10.9 cubic wing loading on my Extra 300. My goal is to build a nice IMAC plane with a 2.5 pounds gas engine in the nose to fly a lot at low cost. 10.5lbs is the lightest possible to do with that plane with full CF hardware and other modifications.
Now i have 2 questions:
1) Can flaperons or spoilerons reduce the landing speed on that plane?
2) If it can, i assume the flaperons will reduce the landing speed by 25%? which inconvenience having 10.9 cubic wing loading?
I am not a 3D pilot but a patttern-IMAC addicted. The only 3D stuff for my flying style is the knife edge and torque rolls.
