The 109 came with no visible defects or warps when delivered. Used the supplied glue for assembling the tail, intake and control horns. Using 850mah 3S which fits just snug in the battery cavity. receiver sits between the firewall and the battery. and balanced without landing gear right at the factory recommended distance.
only needed a few clicks of elevator and it flew nice and level. Handles winds pretty well with the 3S. Great flyer overall and have a nice presence in the air when doing wide sweeping turns.
Only issue with assembling was the z-bend for the rudder was a bit off, and I had to cut it off and redo it to have the rudder straight and not maxing out the clevis threading.
