I had a chance to test fly my new SUKOI today,plane fly's great after I got the balance right. I have a BME 102 engine installed and all the rudder and elevator servo's are in the tail per instructions from Hangar 9.Three 1800 mah battery packs are mounted behind the firewall. I still had to add over 3 lbs of lead to the nose to make the plane balance (this airplane realy fly's bad when tail heavy, I know from first hand experience). With the added lead my SUKOI is at 27 lbs. If I had to do it again I would probably move the rudder & elevator servo's forward ?
