Nice flying Hone. Completed "the build" and flew mine yesterday.
The 60" Laser flies very smooth, precise, and tracks like it's on rails even in light winds. I ran six consecutive packs through it Tuesday morning, and with flight times of 6:30 ~ 7:00 minutes each, the 5S 4000mAH pack comes down at or above 3.75 volts per cell. With an AUW of ~6.0 lbs the Laser flies much bigger than it is and has extremely good low speed stability. It has all the good flight characteristics I've experienced with my 3DHS 74" Edge and EF 70" Extra 300 and not a single bad habit. The Laser hovers and torque rolls darn near effortlessly. I didn't notice any pitch or roll coupling in KE, even with a slightly forward CG. But of course flying in light winds would tend to make slight coupling difficult to discern. Even still point rolls are nice and crisp.
Setup info: HS-7245MH, Torque 4016T/500 V2, Xoar 16x8, CC Phoenix ICE2 HV80, 526g 5S 4000mAH pack. With the light weight pack (compared to a 5S 5000 etc;-) all the way back against the wing-tube the CG is still just a little forward of that needed to achieve a good straight and inverted 45° up-line. Before the next outing I'm going to move the ESC further back from its current position on the bottom of the motor box and just forward of F1, to behind F1. But as is the Laser flies great in windy conditions (CG at the front of the wing tube).
Love the new 60" Laser.
