Hezik ... okay I read you, 5kg plane trying to pull a huge loop up there where there is a strong wind unlike a 3D plane that is flying at eye level most of the time. You want that reserve power when you need it. I seen some F3A birds fly really well on about 500W/kg and they tell me they hardly push to full throttle for a P09. Thanks for the info ...

I have seen all the new F3A designs and they are suppose to be designed for P09 etc etc etc. How come a design like the YAK55 can come in 8th or is it a combination of a decent plane and a darn good pilot? Any takers?
