RE: kangke laser2000 what size engine?
Tail Heavy
Don't use the ZDZ 60, too much weight. I have a Laser 2000 with the DA 50 and it has plenty of power for the laser, it will hover at around 50% power with a strong pull out from hover. By the way I am using all the stock gear that comes with the plane and total weight is 16,5 Lbs.
