Well, I flew the Laser this morning with the O.S. .91 II 4-stroke.
As expected, it had GOBS and GOBS of power and the motor isn't even broken in yet!
The C.G. is a little bit too far foreword. I'll need to move the battery further back and maybe add a touch of tail weight. Not really nose heavy, just not where I like it.
It flew every bit as well as my first Laser 3D (with a TSI .46 2 stroke for power) and in some ways better. I flew it 5 times this morning , a couple of trim flights and a couple of "let's see how much stress this airframe can handle flights" I loved every second of it.
The Laser is by far my favorite airplane to date, I know there are several similer designs out there so don't flame me for saying that. I'm sure all of you Dioblotin-no limit-diablo-seduction-u can 3D-extreme 3D etc..etc.. owners are very happy with your planes as well, i'm just happy with this one.
The plane weighs in at just over 5 1/4lbs dry with the .91 in the nose. I'm running an APC 14 x 6 prop at the moment, this thing hovers at less than 1/4 throttle with the engine still burbling rich
and accelerates out of hover like a rocket. About what I expected with the bigger motor, what I didn't expect is that the plane still flies very light even with the extra weight in the nose.
Spins are lots of fun, although not super tight. Waterfall and snaps aren't as "snappy" as I would like, but thats probably due to the slightly off C.G.. Moving the C.G. back a bit should improve
it.
Blender with this plane (and my earlier Laser 3D) is a blast. You can easily flatten out the spin and it just stops dead in midair, Add a little power and you've got a really sweet climbing inverted flatspin. Climb a bit nose it over and start the manouver all over again, like I said , sweet.
Gonna make a few small adjustments tonight and try it again ASAP. I'll post again after I fly it again.
