Servos and weight
Digitals - had the rudder laying around from a burnt up Sig - smooth and fast for rudder. The tail servos just seemed to fit. Wanted to try a digital on throttle to see about a real accurate idle - definitely worked.
Minis anywhere would be way slow but light. Used to always use mini on throttle but an ultra low idle with the accuracy of a digital makes it slow on a dime. Won't use any more slow servos.
Lighter battery pack would be awesome.
Keep it light yes.
Lightest wheels Kavan. I have H9 light wheels but Kavan at least an ounce lighter.
Still push for 4 stroke. A world of difference between a 14x6 to a 15x5. Started with a 13x6. Too much pitch and your back in the 80's with an Ugly Stick on a 60 with a pipe.
Bigger the prop more right thrust and you will need some down.
This plane gains nothing with speed.
I am 1/2" back from recommended rear and it could go much further back. I can literally stop in the air nose up with no stall.
I was hoping for more out of this plane. But it does keep you focused when you ring it out.
