Just as great as its stunning aerobatic performance is its ease of use. The two-piece wing makes transport to the flying field a cinch, and its expert engineering lets the whole plane assemble as easily as an erector set. The aluminum landing gear brackets keep the gear mounted in the model—another sign of Hangar 9's excellent engineering. And it's covered in genuine Hangar 9 UltraCote for the perfect look.
Designed by TOC competitor Mike McConville and exhibiting both fine flying capabilities and an expert look, Hangar 9's new Extra 330S 33% ARF is unquestionably a plane to put a smile on your face.

Here are some articles we think will be of interest to you as you consider Horizon Hobby products. We'll add new relevant articles as they become available.
The cowling is approximately 11" wide.
We do not have a hardware pack for Hitec servos. You will need to purchase hardware individually.
Using a computer radio, you can mix elevator and aileron to rudder to make knife-edge track straight. Also you can mix elevator to spoiler on a switch to aid in elevator and harrier maneuvers. Keep in mind the lower the weight of the plane; the better it will fly, so keep additional weight to a minimum. Also a lightweight, a high power 80 cc engine will give the best performance.
It is recommended to use a PCM system with gasoline engines. This will help prevent any interference issues that may develop. A computer radio is definitely encouraged, as it will greatly simplify the setup of the plane, and you will be able to use the radios features to your benefit to improve the flight qualities of the plane.
You will need 80 oz in of torque or better for the flight surfaces. Keep in mind that the better servos you get, the better the plane will fly.
We do not recommend any engine over 80cc. Anything larger will void the warranty on the plane and can lead to failures. It really flies better with a lighter engine anyway. For customers who want super power, it is best to use a lightweight 75 or 80cc engine such as the 3W or ZDZ. We recommend the G-62 for sport flying or the GT-80. The G-62 will fly the plane but vertical performance is limited. The GT-80 will give good performance, but at some altitudes and in hot and humid weather the performance will be limited. You may have to change the length of the firewall if a shorter engine is used. 1" diameter hard wood dowels work very well as spacers for the engine, just cut them to the length needed.
Give the ailerons a pull test to be sure that the hinges are secure by carefully holding the wing, and pulling on the aileron. Be sure not to apply too much pressure, or you could damage the wing or the aileron.
Be sure that the aileron seals do not prevent aileron movement or make excessive noise while moving the ailerons.
The Matchbox option listed is a very good idea to ease the set up of the ailerons to prevent any binding or fighting of the servos. This will make the set up go much easier and quicker. Be sure to use 1” arms for these servos. Follow the recommendations for the set up or flutter can occur. Take your time setting this up to prevent as much fighting between the servos as possible. An amp meter such as the Hangar 9 meter part number HAN172 will be of great assistance in setting this up. Put it between one of the servos and the receiver and minimize the amp draw at all deflections of the ailerons by adjusting the control horns and servos. This is very important, as an incorrect set up here will lead to a loss of torque available to the control surface which can lead to flutter.
The wings can be difficult to put on the first few times as they are made to be a tight fit, so just take some time and if you have someone who can help hold the plane it will go on easier. Holding the blocks in the fuse that the anti-rotation pins go through while pushing the wing on will make this a little easier also.
You will need to clip off around 1/8” or slightly over off the hinges that go into the stab for the inside hinges, as they will hit the stab tube and not go in all the way. Dry fit the parts (assemble without glue) before using epoxy on the hinges to be sure that the elevators will install completely and get a tight hinge gap.
Give the Elevators a pull test to be sure that the hinges are secure by carefully holding the stab, and pulling on the elevator. Be sure not to apply too much pressure, or you could damage the stab or the elevator. Be sure that the elevator seals do not prevent elevator movement or make excessive noise while moving the elevators.
Be sure to use 1” arms on the elevator servos.
Be sure to use the 1 ¼” arms on the servos for the rudder only.
Move the battery position as needed to achieve the CG recommended.
Glue in a small piece of 1/8” ply under the servo screw holes to provide more wood for the screws to hold onto.
Check the cowl mounting blocks on the fuse to be sure they are securely glued to the firewall. If not, add a little epoxy around the mount.
You may need to move the battery further back for the GT-80, and forward for the G-62 and other light engines. Move the battery as much as possible, to try to avoid adding weight. The completed plane is very light, so if you do have to add some weight, it really shouldn’t affect performance much.
Just be sure that all functions work ok and are setup properly. Also be sure that the servos are not fighting each other creating excessive amperage draw on the ailerons and rudder. If the current draw is too high, it may lead to servo gear wear, servo failure, or flutter. Great care must be taken in the set up of the aircraft to prevent any serious problems in flight.
For more power with the GT-80 follow the performance tip given of drilling the 8 – 5/16” holes in the baffle of the muffler. This can be difficult to do, but does give a performance enhancement.
