I'll keep you informed on its maiden flight with a debrief. Previous to this style plane all I have flown are 1/4 scale IMAC airframes.
You asked about the build. I'll start out by saying, looks are deceiving. The color scheme certainly looks appealing but the covering job leads alot to be desired. I had air bubbles and sags all over the entire airframe. After many hours it finally looks presentable. I'm not a professional "Monokote" expert but I no how to apply it properly. There work staff either does not or don't care. Another area of concern is the elevator mounting plates. I had one seperate from the fuselage structure whyile installing the servo. The other one was ready to seperate also. The next area to fault is the installation of the fuel tank and also its removal. If
you install the throttle servo before installing the tank you won't be able to install the fuel tank. Leave the throttle installation alone if you have to work in the fuel compartment.
A word of caution. After I ran the engine in the airframe I ckecked for anything coming loose and I found both wing holdown screws were loose. This is caused by engine induced airframe vibration. Apply some silicone adhesive to the threads and this should cure the problem.
