Seagull Models Maule Super Rocket 10-15cc ARF





The M-7 Super Rocket, part of the Maule family, took its first flight in the mid-1980’s. To this day, the Super Rockets remain very popular in the aviation world. With their high-performance engines (both piston and turboprop varieties) and short take-off and Landing (STOL) characteristics, they are hard to beat at unimproved airstrips around the world. Though the Super Rocket and its other family members are so highly regarded in the aviation world, there aren’t many companies producing models of the M-7.

When Seagull Models announced that they were going to produce not just a model, but an ARF of the Super Rocket, I just had to have one! So, after a few emails back and forth, Seagull sent me one of their pre-production samples – this will be the fifth in my series of reviewing these samples.

Though these pre-production samples are, at times, more difficult to assemble and review than production aircraft, they have brought me an opportunity that I may not have otherwise had. I have the opportunity with every model to speak with the manufacturer and tell them where I see concerns and what needs to be changed. This has been one of the cooler things I’ve been able to do in my adult life!


So, sit back and have a look at this incredible STOL aircraft – I’m sure you’ll be glad you did!

As I stated in the intro, the Maule Super Rocket is the fifth airplane in my new series of pre-production samples from Seagull. Because it is a sample, it arrived in a plain brown box. Rest assured that by the time you read this review, the box will have a full-color label with all the specifications and recommended equipment listed. Most of the parts were either bagged and taped together or separated by cardboard inserts. All parts were accounted for, and they were in perfect shape.



The parts layout is standard for most ARFs so assembly should go quickly. I like the black on Yellow trim scheme, and there wasn’t a wrinkle in the covering to be found. It looks as though the design team at Seagull had their hands full when they put the Super Rocket together – there are a lot of curves on the belly of this plane!



There are two large hatches in the belly.The forward hatch is for the fuel tank or LiPo battery, while the rear hatch covers the tail servos. Each hatch has a tab at the rear and is secured with two machine screws. While technically not a design flaw, I would have liked to see the forward hatch be secured with a spring latch or magnets. The two machine screws could be a little time consuming during flight battery changes. The good news, though, is that the hatches certainly won’t come loose unexpectedly in flight!

The paint on the fiberglass cowl perfectly matched the color of the UltraCote. I also liked the fiberglass tabs at the wing mounting area – they slide into a slot in the root rib of each wing half, and a machine screw secures each wing half to the fuselage via the tab.



Seagull has kept the great looks of the Maule’s tail and made an easy-to-assemble-ARF at the same time! Nice job, Seagull! A printed instrument decal is pre-installed at the factory. I really like the fiberglass control horns Seagull has been using. They are simply epoxied into slots in each control surface.


The aluminum main landing gear is more than strong enough to support the the Maule, and the steerable tail wheel assembly looks nice as well! Like most of the newer Seagull ARFs, the Maul comes with parts for glow, gas, and electric power options.

Items Used for Completion



From the ground, I will be using my trusty Hitec Flash 7 transmitter. This 7-channel transmitter is very quickly becoming one of my favorite! It feels good in-hand, and the sticks and switches are where they should be. A very nice LCD display makes programming a breeze, and shows me telemetry readouts as well!



I will be using a Hitec Optima 6 receiver in the Super Rocket – The single antenna makes the Optima 6 easy to install nearly anywhere inside a model!


Speaking of control surfaces, I will be using Hitec HS-485HB deluxe standard servos. These are great servos, and available at very reasonable prices. With a ball bearing on the output shaft and 83 oz-in of torque (@ 6.0 V) these servos are great for aircraft up to 12 pounds!


An Electrifly Rimfire .80 brushless outrunner motor (5055-500kV) will be mounted inside the cowl. The Rimfire .80 should provide ample power to pull the Maule around!


A Hitec Energy Sport 80 Amp ESC will provide power to the receiver and servos – These new ESCs from Hitec are great, and affordable as well! With a retail price of under $60.00, the Energy Sport ESC gives me peace of mind, knowing my plane is backed by a great company!


Finishing out the front end is a Falcon 15×6 Beechwood electric propeller. These props not only perform very well, but they look great as well!





Since I was assembling a pre-production sample, I didn’t have the manual while assembling the Maule. But, I did have a chance to talk with Seagull and help edit the manual you will see in the box. As a result, I’m going to have to say that this is one of the better manuals not completely written in the US – there are lots of illustrations, and the instructions can be well-understood! Any intermediate modeler will have no trouble reading through this manual.




Wing Assembly


I started wing assembly by installing the ailerons and flaps. The ailerons are installed with CA hinges and thin CA, and the large flaps use four composite drop hinges – the drop hinges are attached to the wing and flap using six wood screws.



The aileron and flaps servos are mounted on their respective hatches. A pre-installed pull string makes short work of pulling the 18″ servo extension through the wing. I then mounted the aileron servo hatch using four wood screws, and epoxied the control horns into slots in the flaps and ailerons. If you’re quick enough, you can get all four control horns installed with a single batch of 5-minute epoxy, but a slower curing epoxy will give you more installation time.


When the epoxy had cured, I assembled the aileron pushrod, bent and cut it to length, and secured it with a snap-keeper. After installing the flap servo hatch, I assembled and installed the flap pushrod in the same manner.

Tail Assembly



I slid the wings onto the aluminum wing joiner tube, set the stab and fin in place, and checked the tail for proper alignment. Everything looked perfect, so I drew a centerline on the stab and pinned it in place for tracing.


With the fuselage and fin sidelines traced onto the stab, I cut and removed the covering from the stab and installed it with epoxy. When the stab epoxy had cured, I installed the fin with a second batch of epoxy.


While the epoxy was curing on the fin, I epoxied the three control horns into the elevator halves and the rudder. When all the epoxy had fully cured, I attached the elevator halves and rudder using CA hinges and thin CA.


Pushrods and Fuselage Electronics Installation



The elevator and rudder pushrods were then assembled and installed, along with the three fuselage servos – The outer two servos are for the elevator halves and the center servo takes care of the rudder. I bent and cut the pushrods to length and secured them to each servo.



The Hitec Optima 6 receiver was secured using a pair of zip ties and a small piece of DuBro 1 4″ foam rubber. All of the servos were connected to the receiver, including the four 12″ servo wire extensions for the ailerons and flap servos, and the rear hatch was secured with a pair of machine screws.

Landing Gear Installation



The painted aluminum landing gear consisted of three pieces, plus the axles. There is virtually no flex in the main gear once it’s assembled, but the tires will provide a little give on hard-packed runways.



The tiller arm is attached to the bottom of the rudder with two wood screws before installing the tail wheel assembly. Two machine screws held the tail wheel assembly in place, and two springs were cut to length and installed to connect the tiller arm to the tail wheel.



Motor,ESC, Cowl and Prop Installation




On to the business end of the Maule! I started by marking the motor box and tracing the Rimfire .80’s aluminum mount onto the motor box. With the mount’s location marked, I was able to drill the four holes for the Rimfire .80. The motor box was then attached to the firewall with four machine screws – a drop of ZAP Z-42 blue thread locker was applied to each of the four machine screws before they were installed.



The Rimfire .80 was installed on the motor box, and the Hitec 80 Amp ESC was installed inside the front battery hatch area – a small Velcro strap secured the ESC to the battery mounting tray. The battery and retaining straps were added next.



With the forward hatch secured in place, I used the ‘card stock and tape’ method to install the cowl.



The Falcon 15×6 Electric Beech wood propeller and spinner were then installed.


I epoxied the pilot figure to the Maule’s cabin floor and installed the windshield. I like to use Formula 560 Canopy Glue to install windshields. It’s available from ZAP and Frank Tiano Enterprises, and is the cleanest, easiest way to install windshields. After running a bead of Canopy Glue around the windshield, I taped it in place with several pieces of low-tack masking tape.

I slid the wing tube through the fiberglass tube in the fuselage and installed the left wing – The flap and aileron servo extensions were connected before sliding the wing tightly to the fuselage.



The right wing was then installed, and machine screws secured the wing halves to the fuselage.


We’re almost done! I assembled and installed the wing struts per the manual, and the basic assembly was complete.

I received the manual just in time to set the control throws, so they were set accordingly. All that remained was to check the Center of Gravity (CG). Per the manual, the CG should be set at 70mm (2.75″) behind the leading edge of the wing at the fuselage. With a 5S 4500 mAh LiPo in the nose, the Maule Super Rocket balanced perfectly, and She was ready to fly!














I love the fact that Seagull has produced an ARF of the Maule Super Rocket. Though seldom modeled, it’s a great looking airplane, and Seagull did a good job of scaling it down. While I would have liked to see a magnetic battery hatch, the machine screws are not a deal breaker by any means. The rest of the plane is really nice – it went together easily, looks great, and flies well! Seagull has done a fine job on their new Maule Super Rocket, and I have a feeling that this one will be around for quite a while!
