    During WWII, the P-47 had a few different roles. It served in short and medium-range bombing missions, and could carry over a ton of bombs. The Thunderbolt, or Jug, was also a formidable fighter aircraft. Though it was the heaviest and most expensive wartime fighter, it was also one of the best at protecting its most valuable weapon - its pilot. Surrounded by armor, the P-47 cockpit was roomy and provided a great view!

    Making 2,000 horsepower, the 18-cylinder Pratt & Whitney turbosupercharged engine could haul the P-47 along at a maximum speed of over 430 MPH - that's not too shabby for a plane that could weigh as much as 17,500 pounds fully-loaded!

    New from Maxford USA is the Profile P-47. Designed to be a fun-fly type plane, this plane looks to be a great plane for slow flight, 3-D, and just having an enjoyable afternoon at the field!

  • The Profile P-47 arrived double-boxed, which all but guarantees a safe arrival at ANY destination! Thankfully, the outer shipping box had some labeling on it, because the inner box had no label at all. This does cut down on costs, allowing Maxford to sell the plane cheaper. Besides, how many of us actually keep the boxes anyway? Inside, I found the parts either bagged or wrapped in a protective foam. All the parts were taped together to prevent shifting during the shipping/handling process. There are so few pieces to the plane that I expect it to go together in just a couple of evenings.






    I was very impressed by the covering on the Profile P-47 - there were no wrinkles, and the checkerboard nose adds a nice touch! A couple of the neat features of this profile plane are that the wing can be removed for transportation, and the servo wires are concealed within the fuselage for the tail servos. There is a 'pull-string' in the fuse to pull the servo extensions through the fuselage.



    The large bays in the wings allow for easy installation of electronics, the tail surfaces are 'stick-built' to keep them light, and the landing gear is robust and easy to install.



    Manual


    The manual does a great job helping to assemble the plane, but this is definitely NOT a beginner's project. The manual is directed at more experienced modelers, due in part to just a few illustrations. Also, I feel the manual is written in a way that there are certain things that the modeler should just know before assembling the plane.






    Tail Assembly


    Assembly began with the tail. I test-fit the stab and fin and marked them for covering removal. With the covering removed, I used epoxy to secure the stab and fin, and taped them in place while the epoxy cured.





    The elevator was then installed using the included CA hinges. I prefer to stick a T-pin through the center of each hinge - this ensures that an equal amount of hinge is inserted into the stab and elevator. I found that I had to remove some of the wood at the rear of the stab slot to allow the elevator free movement. With the elevator moving freely, I used some thin CA to secure the hinges.





    Unfortunately, the kit I received was missing the tail wheel bracket. Thankfully, I had a Du-Bro tail wheel bracket on hand, so I was able to keep going on the assembly process. The tail wheel assembly was put together and installed, along with the rudder. The rudder was installed with CA hinges, just like the elevator.





    I attached the 24" servo extension wires to the elevator and rudder servos, and pulled them through the fuselage. I took my time on this step, because the the wires make a couple of 'turns' inside the fuse. The control horns were then installed on the rudder and elevator, and the servos and push rods were installed.



    Wing Assembly





    Wing assembly started with installing the aileron servos - a 6" servo extension wire was attached to the servo in the left wing. The ailerons were then installed using CA hinges.





    With the ailerons in place, I secured their control horns using medium CA. There were pre-drilled holes in each aileron for the horns. I then installed the push rods, and the wing halves were complete.



    Main Landing Gear Assembly





    Installing the main landing gear was next, and took just a few minutes. The gear legs were inserted in the channels in the fuse and then secured with four plastic straps - two on each side. Using my rotary tool, I ground flat spots on the bottom of each axle and installed the wheels and wheel collars.



    Motor, ESC, and Battery Installation


    The P-47 can be assembled with either a glow engine or an electric motor. Because winter was quickly approaching, I decided to go electric - I used the included manual addendum for installing the motor, ESC and battery.





    After a quick trip to my local home improvement store to buy L-channel, I started installing my motor. I cut two 2-3/4" long pieces of 3/4" L-channel (not included) to serve as the motor mount. I drilled matching holes in the two brackets, and installed them using 1" 6-32 bolts, #6 washers, and 6-32 locking nuts. With the mounts installed, I marked and drilled the four holes for the motor and installed the Turnigy 3548 1100kV outrunner motor.





    The propeller was installed next, followed by the ESC and battery. The covering was removed from the throttle servo opening and a small section toward the top of the fuselage for the hook-n-loop strap.

    Reviewer's note: the battery used in the last picture was later replaced by a 4S 4000mAh LiPo pack to balance the plane without adding additional weight.



    Finishing Touches





    Assembly is nearing completion! The wing halves were secured to the wing's center section using the two plywood wing joiners and 15 minute epoxy. When the epoxy had cured, I secured the completed wing to the fuselage using a pair of wood screws and washers. All that remained was to install my Tactic SLT receiver, install the wing-bay covers, and balance the plane. As I stated in the last section, the small 3S 2200mAh battery was replaced by a 4S 4000mAh pack to balance the plane at the recommended center of gravity (CG) of 4" from the leading edge of the wing.


    With assembly completed, I'm ready to head to my flying field and have some FUN!

    November seemed to fly by (no pun intended) very quickly this year, and before I knew it, it was December 1st. Normally, this means close to a foot of snow on the ground in Minnesota, but there was not a flake to be seen! With the temperature getting close to 30 and no wind to speak of, my buddy, Jim Buzzeo, and I headed to the field to get in some 'last minute' review flights! It was an overcast sky, but we can't get too picky this late in the season...

    I taxied the Profile P-47 out onto our textile runway, and noticed immediately that the tail wheel does a good job of directing the plane. But, with the typical profile plane's narrow main gear stance, the P-47 did get 'tippy' when a little throttle was added. It made take-offs and landings a little more interesting, but nothing that any intermediate pilot couldn't handle.

    Speaking of take-offs, when I opened the throttle, the plane came alive! The first take-off was a little shaky (this was the one in the video), but subsequent attemps were made holding just a touch of left rudder - this made the take off roll much better.

    After a quick trip around the field to trim the P-47, it was flying straight and level - three clicks of up elevator and one for right aileron and the profile plane was perfect!

    With the Turnigy 3548 1100kV motor, an 11 x 5.5 prop, and a 70Amp ESC, I had to keep throttle position in mind - there was plenty of power on tap for anything - I felt very comfortable with straight and level flight at 1/2 to 2/3 throttle. With the large control surfaces and micro servos, I was worried about flutter at higher speeds. But there is so much frontal area on the wing that its hard to get the plane going too fast!

    Other than aerobatics, most flying was done between 1/4 and 1/3 throttle - a 4000mAh battery pack will definitely last a while under those conditions!

    Since I mentioned aerobatics, the Profile P-47 can pretty well do it all! Anything I could think of, it did. 3D is easily possible with the large control surfaces and light weight of the plane. I'm not a great 3D pilot, but I could fly the P-47 around, with ease, in a high-alpha position, and got some hovering in as well!

    At the 10-minute mark on my transmitter, I brought the Profile P-47 in for a landing. The plane slowed down to a crawl, and seemed to just hang in the air above the runway! I set the P-47 down easily and the plane rolled to a stop - the narrow gear came into play again, but was not a big deal. After a quick check on the battery, I put the plane back up on the same battery! The 10-minute flight used just under half of the battery's life, so I was able to fly another 8-minutes without fear of running the battery too low!

    Reviewer's flight tip: If you'll be flying the Profile P-47 from a hard surface, such as asphalt, I would definitely recommend wingtip guards be added.

    When it comes to warbirds, the P-47 is right at the top of the list on the 'most-modeled'. With so many scale versions of the Jug, what makes the Maxford USA P-47 stand out? Nothing in the scale market.

    But it's not a scale model. It's a profile plane. This plane was designed for fun - LOTS of fun! It assembles quickly, flies slow and easy, and would be a great plane for anyone looking to just fly for 'the heck of it'!

    Wing tip guards? Yeah, and SFGs and wheel pants too… Gotta have some cool WW2-looking wheel pants. Tru-Turn makes some nice scale spinners in this size too…
