The Grumman G-44 Widgeon was the little brother of the famous Grumman Goose and the smallest seaplane ever produced by that manufacturer. The prototype Widgeon first flew on July 22, 1940. With the advent of World War II, the 6-person Widgeon was quickly placed in service with the Coast Guard and U.S. Navy for use on search and rescue missions. It would later serve the Navy as a transport and even as an amphibian trainer. The U.S. Army would also use them as observation planes. Of the 276 G-44 Widgeons produced, only about 35 remain in flying condition throughout the world today.

Possibly the most famous Widgeon was featured in the opening sequence of the popular 1978 TV Series "Fantasy Island". Referred to as "De Plane!, De Plane!" by actor Hervé Villechaize (Tattoo), N4453 had a somewhat checkered past that included drug running prior to its starring role in the series. This very famous Widgeon now resides in the aircraft collection of an antique dealer in Hollister, Missouri.

The ElectriFly Widgeon accurately captures the graceful lines of the original Grumman seaplanes and the colorful Monokote trim scheme is very pleasing to the eye. Reliable electric power takes much of the worry out of twin motor operational risks and greatly speeds up the build process. I think it's about time to get started building this one.

The 24-page instruction manual includes numerous illustrations and pictures and helpful building tips. Seasoned ARF builders should have no problems with this plane. However, newer modelers may need to get a little help from someone with more building experience.

Assembly begins with the wing center section. The first order of business is the installation of motor mounts, motors and motor lead extensions. I chose to route the motor leads through the top opening of the motor mount bulkhead rather than take them through the larger opening lower in the mount. My hope was to keep the leads as high on the wing as possible and as far away from water exposure as possible. The motor leads were binding slightly on the top motor mount opening, so I used my Dremel and raised the opening a little to clear the wires.

Next comes the installation of the servos in the outer wing panels. The recommended Futaba S3114 servos were a perfect fit in the cover plates. I used Vaseline petroleum jelly to coat the top of the servos and the servo output shafts before I installed them in the plates to help waterproof them.

Once the servos and linkage were installed, I discovered that the linkage would bind up as the servo tried to move the aileron surface through its full travel at high rates. The solution was to bend the linkage so that the servo horn and Faslink could move parallel to the wing surface and not be forced up by the surface control horn.

The next step was to trial fit the outer panels and the wing joiners to the wing center section. I found that the joiners were a pretty loose fit in the wing pockets. The result was that the outer wing panels could move over 1/2" at the tips -- from 1/4" dihedral to 1/4" anhedral! I used a long flat ruler to insure that the top of the wing surface was flat and the outer wing panel taper gave the wing a little dihedral effect. A flat top wing surface, or an outer panel with dihedral shouldn't make much difference, as long as both outer panels have the SAME amount of flatness or dihedral.

The fuselage assembly was very straightforward and the pre-installed windows were a big timesaver. However, the rudder and elevator pushrods were hard to install and difficult to operate. A closer inspection revealed that some fuselage paint had flowed into the pushrod tubes and was causing the obstruction and binding. A few minutes work with a hobby knife opened up the tube ends and the pushrods worked fine. I coated both pushrods with CorrosionX before I installed them in the fuselage to keep them from rusting.

I decided to omit the kit's water rudder assembly because I did not like the looks of the non-scale water rudder hanging below the fuselage. Instead, I choose to program throttle differential to provide directional steering control on the water. I found that a 30% mix of Rudder over Throttle gave excellent slow speed and high speed water control.

Radio Installation

Before I began the radio installation, I treated the Receiver, the ESCs, and all the servo and battery connections with CorrosionX. This product is specifically designed to protect electronic circuits and has a 40,000 Volt dielectric strength. Over the years I have found that Murphy's Law has a special clause for seaplanes, and it's not a question of "IF" water will get into your electonics, it's a matter of "WHEN".

Before I installed the ESCs in the fuselage, I ran each ESC with its motor to confirm proper rotation. I found it very helpful to then color code the ESC leads to match the motor extension color code.

The recommended Futaba S3115 servos were a perfect fit in the fuselage and the Futaba R617FS Receiver fit neatly just ahead of them. I ran the receiver antennas through short pieces of tubing to orient the antenna ends at 90 degrees to each other and to keep them away from other wiring and away from the servo arms and control pushrods.

Interior and Final Assembly

I knew I wanted to install the included cockpit floor in the fuselage to help hide the wiring and servos in the fuselage. I also wanted to install a pilot figure to add to the scale appearance of the Widgeon. The problem was that if I permanently mounted the pilot figure on the floor, it was almost impossible to slide the floor in place. I found my solution in hook and loop fastening material. I arranged the pilot figure and applied the hook material to the pilot and the loop material to the cockpit floor while the whole assembly was flat on my workbench. I was then able to install the floor in the fuselage and afterwards easily slide the pilot figure in place.

The next challenge was to connect all the wing wiring to the receiver and ESCs in the fuselage. I decided to use two short servo extensions for the ailerons to keep from having to plug the wing aileron wires directly into the receiver. I guess a short Y-harness would have worked just as well but I wanted to be able to experiment with spoilerons and flaperons at some point.

I soon found that I needed another pair of hands to hold the wing near the fuselage while I plugged in the six ESC connections and the two servo connections. I was glad my wife volunteered to help out. Once all the wiring was in place, I tested the motors and servos to once again confirm proper motor rotation and servo operation before I began the cockpit floor and pilot installation. Only after the floor and pilot were in place, was I able to finish tucking in the wiring and finally bolt down the wing.

The completed Widgeon weighed 3 pounds and 14 ounces. I was able to move the battery around on the battery tray and get the plane balanced perfectly. Before the first flight, I checked the balance on each of the GP 8x6 Slow-Fly props and found they needed balancing. I decided that the best way to balance them was to apply a big drop of thick CA to the tip of the light blade of each prop.

I set the control surface throws at the recommended amounts for low rates and for high rates. Since I prefer to fly with exponential, I then programmed in 25% exponential on low rates and 35% exponential on high rates.



Flying off water adds a whole new level of enjoyment to our hobby. Flying a scale, twin-engined amphibian off water, ramps up the fun and the adrenaline rush even farther.

Taking Off and Landing

The Widgeon plowed up a pretty good bow wave at low speeds and the props would contact that wave and noisily spray water. I found that if I held up elevator as I applied power, the spray was minimized and the hull came up on step quickly and then I could relax the elevator. It was much easier to taxi the Widgeon on step than it was plowing through the water at slow speed. However, there was a noticeable torque effect that required right rudder and right aileron input to keep the left sponson out of the water and keep the wings level as I trasitioned from dead stop to on step. Once up on the step, the Widgeon would accelerate cleanly to flying speed. Just a little up elevator was all that was needed at that point to get airborne.

Landings took a little practice. The Widgeon would bounce and stall if I tried to slow it down too much. Landings needed to be faster than I had anticipated. I had to carry some throttle and speed all the way to the touchdown. My best landings were accomplished by flying the Widgeon all the way down to the water rather than trying to force the flare for the touchdown.

Normal Flight

Once airborne, the Widgeon flew great. The climb out was brisk and very stable. I only needed a little over 1/2 throttle for a comfortable cruising speed and there was plenty of power left when I wanted to show off. I discovered that the torque effect that showed up during takeoff was also present to a lesser degree during rapid throttle transitions. If I punched the throttle, the left wing would dip and if I pulled the power off rapidly, the right wing would dip. This torque effect was not a problem, just something I needed to keep in mind if I got low and slow and then decided to punch it to go around. Counter rotating props might cure this behavior, but I haven't had a chance to try that out yet.


The Widgeon had plenty of power for nice large loops and big stall turns. Aileron rolls were pretty axial but they needed a dose of down elevator half way through to keep them level. Inverted flight needed some down elevator, but the plane was very stable even in steep inverted turns. Snap rolls were very fast and I found that spins took a full turn to recover after the sticks were neutralized. After that discovery, I decided to leave a little extra altitude for spin recovery just in case. It was nice to know that I could wring out the Widgeon with a few cool moves to impress the onlookers when I got tired of scale looking takeoffs and landings.

Is This For a Beginner?

No. Scale seaplanes are not suitable for first-time pilots. However, pilots with intermediate flying skills and a little floatplane experience should have no problems. The Widgeon should make an excellent second or third floatplane.

The Great Planes ElectriFly Widgeon will undoubtedly be one of the best looking seaplanes at this year's premier float flying events. Whether gently floating along on the water or cruising by at altitude, this Widgeon is simply stunning! Great Planes has done a wonderful job of reproducing a classic seaplane twin in a just right-sized ARF package.

Because the Widgeon is a scale model, it will require more attention to the control sticks than a normal sport model, but the results will be well worth the effort.

Great Review Mike
This one has been on my short list since I first saw it. After your review I think I will give it a try next summer at the lake.
Being a twin and scale it has a huge wow factor

Hey Mike ,

Thanx for this great review , it was a pleasure to read. Good idea to bend to pushrod for the ailerons! Landings in the video are beatifull , nice to see that the plane doesnt come to a sudden stop like for example my seabee but it takes a while to run out off speed.
Cant wait to get mine finished.

How many minutes can you fly on a fully charged battery pack ?

Thanks Bart. I set my timer for 6 minutes and the batteries were only down to storage charge voltage (3.85 Volts/cell) when I land. Most of my flights were at about 1/2 throttle with just a few full-power blasts thrown in for showin' off. I would think you could easily fly for 8 minutes and maybe even stretch it to 10 minutes with a little throttle management.

Thanks Stuart. We are very blessed to be on Lake LBJ which is considered to be a "constant level" lake. Other lakes in the Highland Lakes chain like Buchanan and Travis are at all-time record low levels this year because of the State-wide drought.

Mike, have you had a chance to land the airplane on grass yet? I assume this plane could be hand launched and landed on grass without problem to augment water operations but I'd like to hear your thoughts on this as well. Thanks!

First let me say that I have not hand launched the plane nor have I landed the Widgeon on grass. I do plan to fly the Widgeon at SEFF later this year, so I will be taking off and landing on grass at that event. However, Mac Hodges' grass is like the world's largest putting green - the grass is wonderful. I have flown several float planes at SEFF and have not had a problem. The GP SeaWind did just fine on Mac's grass.

From my flights so far, I would be very hesitant to try a hand launch with the stock setup. I think the motors and battery produce plenty of power, but the left torque tendency at low speeds would spell disaster for a normal hand launch. If you set up counter rotating props, then it might be possible. However, because of the high wing loading, you would have to give it a mighty hard throw to get the necessary airspeed. I think I would try to take it off of the grass before I would try a hand launch. Just remember that grass will have more drag than water so it may take a little longer to get to flying speed than it would on water.

As for grass landings, I think they should be fine. Landings will still have to be pretty fast so you will need a much larger area than you might imagine because the Widgeon needs a low approach and a long "slide" area. The grass would have to be pretty short and well manicured or the sponsons might snag and break off.

I guess I'm just trying to say that the Widgeon is a scale model that needs a pretty large area to fly and operate like a club field or a pretty large pond. The plane is not a park flyer or a foamie, so you won't be able to just toss it in the air and then bend it around in tight quarters for a slow landing. If your club field has a nice grass strip, you should be able to comfortably take off and land on the grass.

Hey Mike what a great review! And who did you hire to fly it for you for the super fantastic video?

You gotta reverse a couple of wires on one motor and slap on a pair of Master airscrew 7x6 three-blade props (one a PUSHER of course), on the reversed motor.

Now I gotta get one.

Great review!!! Thanks! I was just wondering... The kit price is included in the review... mabey it would be useful to give a price on the additional requirments to get up and running by putting the going price for the equipment included in the review. Just a suggestion... It seems like very few who do reviews include the cost of needed add ons... This too is useful information even if the buyer would go with his own or different equipment.
