Well guys, I am flying mine for almost a month. I have ZDZ40 in it and weighs 15.5 lbs. I am not bragging but I am having unlimited vertical with this plane. Three other club members have flown it and they were pleased with it, these fellows fly big birds all the time and holds first position in IMAC competitions. By the way, I have 20x10 menz ultra and I will change it to 20x10 standard after 5 gals. 1/2 throttle take offs and glides in for landing. The plane is built solid and holding gas engine very well. I am a happy camper with this plane (my first gas plane). Will recommend it to anyone!!!
