ModelAero Polaris XL Sea Plane Build Series for FPV - Part 7 - Pedestal and Main Wing Install
In this video ( we glue the pedestal to the rear of the main wing and then glue the main wing to the fuselage. It's starting to look like a plane now!

Music is "A Bath Full Of Joy" from the Magix Video & Slideshow Sound Archive 8 - they don't say who the artist is.

The Polaris XL is a 133% version of the standard size Polaris, and the larger size only enhances the flight characteristics that made the original such a popular airplane. The wing loading is even lighter and the gentle flight performance will amaze you, yet the XL is capable of some impressive aerobatics and a surprising turn of speed!

The kit includes precision laser cut 6 mm Depron foam, nearly 10' of carbon fiber spars, laser cut hardware, pushrods, and fully illustrated construction guide on CD. The decal set is optional.

The Polaris XL is a full build, but we've incorporated additional locking tabs to ease construction and speed up the build. We think you’ll find the build to be very straightforward and enjoyable.

Recommended Power Setups:

Package #1: Polaris Motor (2212-6 with 6x4 prop)

This package uses the standard motor recommended for the 100% Polaris, the Suppo/Spinmax 2212-6, which weighs 47g. This motor has a KV of 2200, spins a 6x4E APC propeller at 19,000 RPM, and can take up to 28A for 60 seconds. The motor will draw about 20-22A at takeoff and in full throttle flight and cruise at 12 to 15A.

Recommended ESC is 40A (with optional heatsink) and the battery should be 3s 2200 mAh 20C or better. The Polaris XL with this 220 watt motor flies beautifully at moderate speed and can maintain a steep climb. It gets off the water or grass easily. Typical all-up weight should be 30-32 oz.

Note: We only recommend the 2212-6 if you are building a very light plane. Power is somewhat limited compared to the 2810-9.

Package #2: Larger Motor (2810-9 with APC 8x6 2-blade prop)

This package provides higher performance using a Suppo/Spinmax 2810-9 motor weighing 78g. It has a KV rating of 1350, which means that it turns more slowly than the 2212-6 on a three cell battery. The best propeller we have found is a Master Airscrew 8x6 three-blade; an APC 8x6E two-blade prop also works well, but doesn’t fully exploit the power of the motor. The motor will draw up to about 30A for short periods and 26-28A in sustained high power flying. Throttled back, it will cruise at about 14-16A.

Recommended ESC is 40A (with optional heatsink) or more. While the motor will work well with a 3s 2200 mAh battery of 20C rating, given the heavier current draw a 25-30C battery will give a little more power, generate less heat and may have better life span.

With this motor of over 300 watts, the Polaris XL accelerates rapidly on the water or ground and can go directly into a sustained vertical climb. It’s significantly faster than with the smaller motor. Typical all-up weight is 32-34 oz.

Note that with this motor, the Polaris XL can easily carry a larger battery, such as 3s 2500 to 3000 mAh.
