Introduction

I love Decathlons! There is something about that classic
"High-Wing" look combined with the awesome aerobatic
capabilities that really gets my blood stirring. A few years back I
reviewed the Seagull 40-size Decathlon and it quickly
became one of my favorite planes, so I jumped at the chance to
review their new Decathlon 120.
Although this is listed as an intermediate plane, many people can
attest to the fact that a Decathlon (ANY Decathlon) is not for a
pilot with only a few planes under his (or her) belt. It is a very
deceiving airframe - They LOOK like a trainer, but these are
highly aerobatic airplanes, and their short tail moment trades
stability for agility. Generally, as long as you get a good speed
before lifting off, and always keep in mind that they can bite you
if you're not careful, you'll love them!

  • Page 2 This new offering from Seagull Models sports a 78.5 inch wingspan and takes a 120 - 150 2 or 4 stroke engine. I have had a Zenoah G-20ei sitting in the shelf for about 2 years that has been begging for a home and since it is one of the recommended engines, that's what I plan to use.
  • Page 3 The packaging was pretty good. Everything was individually bagged, but not taped in place so the wings and stab could slide around and I did have one slightly damaged wingtip. Construction was very good. I especially liked the alignment pin on the fin. This makes aligning the tail feathers a piece of cake.
  • Page 4 to cut the rudder hinges off and add new ones after the fin had been epoxied in place. The second thing is not as big a deal, but it was enough to cause me to waste a lot of time. It deals with installing the turnbuckles in the wing.
  • Page 5 Now the control horns can be installed. The hole locations are marked by a pin hole in the covering. I found that I had to clear out one of the holes with a drill bit, but the rest were clear through.
  • Page 6 Zenoah G-20 Spotlight    Zenoah G-20EI    There are holes with blind nuts for the supplied engine mount, but since I was using the G-20, I used its back plate as a template to drill the new mounting holes and Zenoah 20cc Electronic Ignition Gas Engine installed 8-32 blind nuts.
  • Page 7 firewall below the engine. A good tank is supplied, but since I was using a gasser, I couldn't use it. I switched to a DuBro 16oz tank with a gas stopper. For the cowl, I placed strips of tape along the sides of the fuse and marked where the firewall was.

  • Page 8: Landing Gear

    The other end of the wire gets a connector similar to a pushrod connector which I may change to a regular cable sleeve in the future. Now the pushrods (which are pre-installed) can be connected to the control horns and the tail wheel assembly is installed.

  • Page 9: Final Assembly

    The Decathlon uses one servo in each wing, one for the rudder and two for the elevators (no servo reversing necessary). I used JR DS821's for all control surfaces. I was surprised to see that even with the weight of the G-20 and all of its components up front that the battery needed to go under the tank to get the CG on the spar.
  • Page 10 To be honest, I was slightly concerned that the G-20 would have the power to do justice to this 120-size airplane, but the first takeoff put my fears to rest. The Decathlon lifted off in about half of the space I had expected it to.
  • Page 11 see what she can do. The G-20 easily pulled it through all of the typical maneuvers, loops, hammer heads, a split-S, etc. Spins were really nice - the Decathlon both entered and exited them easily. I think the G-20 is an excellent power option for scale flight.
  • Page 12 Even with the nice ground handling, I would discourage a beginner from trying ANY form of Decathlon, but if you're well into the intermediate stage or an advanced pilot, the Seagull Decathlon 120 is a definite keeper! Seagull Models Distributed through Horizon Hobby 4105 Fieldstone Rd.
