Had my maiden flights today,this plane is awesome! Am using a YS.91 FZ up front , twisting a APC16x8 7800rpm at WOT, however this plane doesn't need no where this much rpm to keep it flying at scale speed.This is hard to believe, but I had the throttle only 3-4 clicks up off of idle for scale speeds. The YS pumps out MASSIVE amounts of power,had to gently roll the throttle to maybe 1/2 for a chrisp takeoff then back it down for flying.
I've read quite a few threads about members p-51s nosing over at takeoff. Mine did the same thing, but found the cure. The trick for non-noseover takeoffs is to hold full up elevator and steer with the rudder. The plane rolls out well and will lift off on it's own at 30 to 40 ft.
This bird flys very stable, I set the CG between 4.5 and 4.75 inches back from the front of the wing seated in the saddle, used the perscribed settings in the instruction manual for elevator, came out exactly neutral on the trim and one click to the right on the aileron trim.
Landings were very straight and level, was able to slow the plane way down without any suprises and settle on the mains. Just remember, as weird as this sounds, up elevator is your friend to keep the nose out of the grass. The plane didn't porpoise at all on landings. To everyone getting theirs ready, you're gonna love it, just remember to use lots of extra epoxy on the firewall.(I smothered all joints and painted the firewall with epoxy before flying) Hanger 9 apparently skimped on the glue in this area.
