Finished ours yesterday and flew in the evening.
OK, the kit is OK. Great wood, good cutting, a few design problems. The directions are fairly useless, and the plan is not highly detailed, but then the airplane is not a first build (or even a second) design. An attempt to build this after flying dozens of ARFs would leave one cursing Exclusive Modelbau.
OK, my personal dislikes. The wing does not have the strength for snappier fun flying. All walls and parachutes need to be performed slowly and gently. I have heard too many stories about wings snapping not to take this seriously.
The tail left without flying wires is a recipe for disaster. Full flying wires seem more like a must have than a smart option.
The elevator was hitting the rudder pull cables and had to be trimmed . This was not discovered before finishing, but everything turned out OK. Of course, the airplane is designed for a rear mounted servo, not a pull-pull. Then it is supplied with a pull-pull horn. I can't think of why it was designed that way. I find pull-pull rudder to be by far the best way to control that surface.
OK, so, the airplane came together with a fair amount of work, fuel tank was mounted on the wing tube socket, battery right behind the OS1.60EFI (which is truly an incredible motor), and rudder servo on a honeycomb tray in the rear of the main compartment, and a beautiful set of flying wires on the removable tail (another potential weak point which could easily be glued on if you are not planning on traveling around the world to fly).
Other than these fixable preferences, it turned out beautifully covered in metallic silver, pearl red and metallic charcoal (anthracite) oracover. I'll shoot some photos this weekend.
OK, the best part of this airplane is the way it flies. It's a big fun flyer. It lands at a walk, flips and flops like a Madness, does nicely in high alpha knife-edge (but takes more throttle and speed to maintain altitude in low alpha). Inverted elevator is super stable, normal more wing waggly. Snaps are not F3A snaps and I do not know if it will do a real snap. However, we put only two flights on it so far.
It hovers easily enough, although the winds where pretty high for our test flight and that made trying these manuvers more difficult to feel out.
Anyway, it is a Fun airplane, hence the name Funtana. One word of caution. If you are searching for an airplane that does it all and can be used for beginning in pattern, look elsewhere. It is not an F3A model.
Overall, it's worth it to build and fly if that's what you are looking for.
