that 8lbs is not good news for me. im putting a O.S. 91 4 stoke in mine. My U-Can-Do 90 had this motor in it. it weighs 8.2 LBS and will not hover because of power. the advertised weight is 6 to 7.5. A 91 will hover that weight... I hope their weight advertisements arent Bogus. I am going to use the stock mounts and horns. and the stock tank... I did a CC to OZ conversion. the tank is 10.9 oz. that is close to 12 by 1.1 oz. I have a 14 in my U can DO. It will fly 18 min. so my guess is 15 min with this tank. I am finally going to have time to start on it this weekend. I will try to get some pics up as i run in to bumps in the road.[8D]
