Assembly:

                In the small, but efficiently packed box, are the fully assembled fuselage, hatch, wing panels, horizontal and vertical stab, cowl, gearbox, carbon fiber landing gear and all of the hardware. 

                Construction begins with the wings, of which there is not much to do.  The wings are plug-in style and do not require any work to mate them to the fuselage other than the attachment of the ailerons with 3 mini-CA hinges.  All hinge slots are pre-cut and the ailerons go on extremely easily.  Following the Aileron hinging, two servos are installed and the included hardware.  The wings are then attached to the fuselage with the carbon fiber wing-tube and two 4-40 cap screws.  There are two positions for the wing!!! One forward for extreme 3D and one that is further back for precision and sport flying.  As per the recommendations, I installed the wing in the rear-position to start, and then aligned the tail group before gluing them on, and hinging their surfaces and installing the servos in the tail along with the included hardware.

               Installation of the motor includes gluing a hardwood stick to the front two bulkheads of the fuse, attaching the included gear box which is designed for a stick mount.  Prior to mounting the gearbox to the mount, I mated the E-Flite Park 400, 4100KV motor to the gear box and insured proper mesh and backlash of the pinion and spur gears.  This is simply done by slipping a piece of thin paper between the pinion and spur gears, and tightening the motor to the gear box.  If you do this correctly, you should be able to remove the paper by turning the gears by hand. The gears will leave an imprint on the paper, but will not cut it or bind up. I followed up this installation with a small dab of lithium grease to lubricate the gears (I check this frequently and apply as necessary)   Taking the proper time doing this will not only ensure that your gear train will have the longest life possible, but it results in a very quiet drive train and eliminates the often loud and annoying whine of gearbox drive trains.

Following the motor installation, the cowling is attached with four wood screws, the landing gear is attached with 2 4-40 bolts and the wheels and wheel pants are installed with the included hardware.  At this point, you install your ESC, receiver and hook up all wires.  Check to make sure you motor spins the correct direction with the gear box, if it does not, reverse any two wires from the speed control to the motor and the motor will change direction.  Install the prop and included spinner, battery, and check the balance and your ready to go flying!!!  I had the Mini-Funtana flight ready in under 3.5 hours including all of the soldering for the various ESC, motor, and battery connectors which is excellent for an impatient person such as myself!

Flying:

Overall, my initial impression is WOW!!! This thing is great.  No real bad characteristics and flys like a much larger airplane.  I am extremely pleased with the flight quality and capability of this airplane.  I would definitely not hesitate to purchase another if I destroy this one!  A quick rundown on the flight characteristics:

Takeoff:  Take offs are un-eventful and as easy as they come.  With all the power from the Park 400 motor, the Mini Funtana is airborne in just a few feet.  Vertical climb-outs or pop-ups into a hover are always fun as well as a lift off to positive snap to knife-edge climb out are also no sweat with this bird.

General Flying:  This airplane tracks very well (much like a pattern plane) with crisp, axial rolls, excellent snaps, loops, hammerheads, and the entire assortment of precision aerobatic maneuvers.  If you a guy that likes to fly laps with the occasional loop or role, this airplane will definitely meet your needs.

Landings: Uneventful.  Like a larger airplane, keep a little speed up until final flair and the airplane will settle right in with no bad tendencies.

3D Flight:  This airplane was designed for 3D and 3D it does! Hovering, Walls, Blenders, Positive and inverted harriers, torque rolls, waterfalls, positive and inverted harriers, high alpha, you name it, it does it all! If you are looking for big 3D performance in a small package, this is definitely your bird! I was so comfortable with this airplane on the maiden flight that I had no reservations bringing it down low and slow.

Hits:

Super-high quality and excellent construction

Extremely Light

Minimal Assembly time

Hardware is excellent

Flying quality is outstanding!

Misses:

None at all with the aircraft

The E-Flite Park 400 4200KV motor does get pretty warm and running for long periods and high power levels is not recommended by the manufacture. This is understandable upon realization of the power level and the performance of this setup.  As a safeguard, I have since purchased a 20mm heat-sink from HiMaxx for around $2.50 that is ultra lightweight and seems to have made a dramatic difference in engine temperatures, well worth the $2.50!!!
