I'd call that a success for sure👍.I've heard these type of planes can be a bit troublesome to dial in, and the pitch thing is to be expected, so it's no surprise she needs a little tuning. The fact the plane flew so well with only minor issues right off the bat is a great start and shows your experience. I'm sure I'm not the only one here who would have had a lot more trouble getting that to even fly controlably. Looking forward to hear/see how this one flies when you smooth the bugs out.
You are correct but not for the reasons you might suspect!
The fuselage was the first I rushed together and I made an error in the plans which meant that the required side and down thrust was not possible as cut, so I squared off the fuselage nose on purpose!
With the different power plant I was going to require different angles over those from the plan and also I wanted to see how severe the thrust angles could be! Best way to quantify the issue is to determine them for yourself so this version was always going to be my test bed to determine the required thrust angles for the different motor/prop combinations I may use.
With a SF prop there is no real requirement for side thrust but as mentioned there is a need for down thrust. The required angle can be plotted simply on this type of plane and so the down angle has already been set and no awaits the verification test flight!
Have fun!
