Alfredbmor:
Congrats on your flights, glad to see maiden flight day for you.
Sounds like your plane is in need of cg adjustment, however i have spoke with some pilots who prefer their plane slightly tail heavy for aerobatics.
After a good rain yesterday the grass was only a little damp this afternoon, and low wind So i got my plane ready for flight.
I had installed a 12 oz. sullivan fuel tank, so after filling i removed about 2 oz.s in keeping with 10 0z. recommendation for first flight and trimming.
I double checked engine and engine mount bolts, servo screws, control horns screws, and after satisfied everything was tight,
It was time for range check and flight.
Take off was very smooth and straight with just a nudge of right rudder. A couple clicks of right aileron and couple down elevator trimmed it for level flight at 3/4 throttle.
One thing the inst. manual omitted was adding differential to the ailerons. I set mine at 3/8in. up and 1/4in. down to help with rolls and aerobatics.
Elevator low rates at 5/8in. up and for outside loops- 3/4 down. Rudder was full deflection
No exponential on low rates. On high rates i left all control surfaces full deflection (for now) with 40% expo on ailerons/elevator and 60% on rudder.
The plane tracked very well after trimming, I flew a couple rounds to get the feel for how it reacts, then took her a little higher for safe margin and tryed a couple inverted passes.
It does this very well with a little down elevator input . (may need ajustment)
Still at safe altitude i tryed a couple snap rolls, this plane does them very well (fast!!) The rudder on this plane is as big as some 60 size planes so knife edge was not only possible, but easy to do
I looked at my timer and unfortunatly it was time to land.[&o]
Landing was a pleasure with this plane, like a low wing trainer,probably thanks to the wing dihedral.
It didnt show any signs of wing drop as it slowed for landing.
As i suspected it keeps a good momentum after throttle cut so i gave it plenty of runway to land.
Shortly after landing a a couple small rain drops hit me in the face, so it was time to call it a day.
After flight nothing was found to be loose, and the renforced landing gear seemed to smile right back at me.
I will try to fly again this weekend .
Good luck on your flights guys![8D]
