The Tower (or Flyzone) Millennium Master is a favorite sport plane of mine. It has great performance and quality and is a terrific value. No other plane of it's type flies as well for so little money. But, no one said "foam is forever" except as a joke! As time goes on, and with many trips to the flying field (a very rough field, too!) the MM had become "not so fresh". My rough field conditions weren't the best for a trike gear plane, and I really wanted to either convert it to a tail dragger or just eliminate the gear and belly land. I had eliminated the gear on my 3 other Tower 1 meter foam planes, the Hellcat, Corsair and P51, and they all improved their already great flying characteristics after ditching the gear.

The need to start my modifications happened when I put an 1800 4S battery in the MM and attempted to hand launch it. I'd hand launched it many times before with various 3S batteries no problem, but this time, I might have had the CG a bit too far forward. Whatever the combination of reasons, it nosed in hard at the launch, and obliterated the lite ply motor mount box, flush with the foam fuselage nose. The flimsy cowling was split in a few places as well. The X mount on the motor had 2 bent legs. The X mount is one of a very few weaknesses of these motors. Once they bend, they cannot be straightened as they break at the motor fastening screws where there is very little metal. The bolt pattern of the motor is unique, and Tower will sell you another motor with the mount for $19.99, but they do not sell just the X mount. I hope to 3D print a replacement X mount once I'm able to use design software successfully.

The shattered cowling situation can also be remedied using parts from Tower that both cost less AND look better than the original MM pieces.

The Tidewater is a great first seaplane. The water handling is easy, precise.  Takeoff runs are quite short and non-tricky. Landings are also very manageable and enjoyable. It's the flying in between the water handling and water landings that can get somewhat stale after many flights. Not that it flies poorly,  or demands that it be flown fast lest it fall out of a turn like a shot duck, but it does have some shortcomings that begin to become tiresome after a while.

The first of these annoyances is the continual wing rocking if even the slightest breeze is present.  It would seem to be the result of the wing's dihedral along with the side area of the tips floats. This was neatly solved by the installation of a Lemon stabilized receiver. In addition to eliminating the wing rocking,  the Lemon makes the Tidewater fly like a bigger,  more stable plane.

The second annoyance is the effects of high, pylon mounted motor.  Increasing the throttle also increases a nose - down force that effects ground, water and flight handling negatively.  Ground (and snow ) takeoffs have the nose burying itself in the ground (or snow ) as  the throttle is advanced  (even slowly ) and  full up elevator is required long into the takeoff run. In flight,  the off axis thrust makes rolling maneuvers uneven and awkward. Inverted flight, while possible, has to be worked at. An eighth inch of up elevator trim is required for normal level flight with the CG set near the recommendation.

The third...Continue Reading
