Hobbyking Pitts Special Manual
The HobbyKing® ™ Brushless Pitts Special is as exciting to look at as it is to fly! It's scale details complete with wheel pants and Pitts livery make it a very attractive plane, however the excitement doesnt stop there! This little foamie is equipped with 4 ailerons to give spirited aerobatic performance and the included oversize outrunner and 10x4.7 prop gives more than enough power for all aerobatic flight, and when you feel the need to turn it up a notch just switch the 10x4.7 for a 11x4.7 propeller for hovering capability! All this and still this little foamie is very controllable at slow speeds. This plane loves a walking speed fly-by. A combination of scale looks, excellent flight characteristics and great power plant make this fomie a real winner. The Pitt's comes 97% pre-built and will take you around 10 minutes to attach the main wing and include your own receiver.

As others have said, the suggested battery does not fit in the battery bay.unless you cut out the thin plastic at the front of the battery bay and a little foam for the wires and plug to fit through.
The turnigy 1300 fits easy and the 1500 almost perfect as it is deeper. I`m not sure about how long the plastic struts will last (very cheap) but overall a great plane and i plan to fit the HK sound system next with a new battery box for a turnigy 2200.
I want to buy another! So far i bought about 7 planes from HK and i was always happy with the product. This time i bought this Pitts and I'm absolutely disappointed with the quality of this particular plane.
I have 40 EPO Airplanes and this one is definitive the worst quality i have ever seen so far. When i installed the lower wing there was a 1/4' gap between the fuselage and the wing. Be ensured i checked several times ensuring that I did nothing wrong.
In the manual, prior to assembly. Meaning of Special Language. Thank you for purchasing the E-fl ite ® UMX™ Pitts S-1S ultra micro airplane.
When i installed the upper wing i observe a similar thing. On one side of the two wing struts there I found again a big gap. Aileron connection rod clips do not line up top to bottom wing. The steel wire to drive ailerons is installed with a sticky tape. I would be amazed if this will hold. By the way someone already described that this steel wire on the ailerons came loose during flight.

IMPORTANT NOTE: While assembling the Great Planes Pitts Special ARF, you will encounter a number of areas that require the installation of various brackets and other items. Most of the locations for these attachments have predrilled holes for these applications. ❏ ❏ ❏ ❏ ❏ 3. Cut twenty-one 3/4' (19mm) x 1' (25mm) hinges from 7.

Join the Bottom Wing ❏ ❏ ❏ ❏ 14.Place the push rod assembly from step 13 on the aileron control horn. Center the servo arm on the servo and align the aileron with the trailing edge of the wing. Place a 4-40 Metal Solder Clevis onto the servo arm and mark the location of the push rod as shown in the sketch above with a felt tip pen. Join the Top Wing After properly fitting the wing halves together check for the correct dihedral angle. Place one wing panel on a flat surface and measure the distance from the elevated wing tip to the tabletop.

This distance should be 5-1/4' (135 mm). Note: You will need to hang the aileron servo off the edge of the table in order to get the wing flat on the table as ❏. Place the belly pan on the bottom of the lower wing ❏ ❏ 4. We will now glue the left wing panel and the center allowing it to center over the wing bolt holes (you may want to section together as one unit.

When satisfied with the position, mark the location for the two holes in the bottom of the interplane struts. Remove the interplane struts and drill these two holes with a 1/8'. technique that was used while adding the belly pan onto the bottom wing. Again, be careful not to cut into the wood while removing the MonoKote. Slide the stab back into the fuselage, leaving the exposed wood outside of the fuselage joining area.

Assemble the tail gear by placing one of the 1/8' (3mm) wheel collars and 4-40 setscrew onto the vertical wire portion of the gear. Then slip it into the tail gear bracket. Attach the steering arm onto the wire on the top side of the bracket as shown in the photo. Mount the Landing Gear ❏ ❏ 3.
Position the landing gear spats onto the landing gear. Carefully align the leading edge of the spat with the leading edge of the landing gear.
Drill the 3/32'(2.4mm) ❏ 1. To mount the main landing gear set it into place using holes through the spats and the landing gear in the the above photograph for the proper orientation and mark the locations shown in the above photograph.
Slip the 5/32' x 2' axle through the wheel pant and place the bearing block over the axle shaft. Hold the block in place against the outboard side of the wheel pant so that the wheel pant is level and straight. Mark the location of the block on the inside of the wheel pant. ❏ ❏ ❏ ❏ 10.

Clamp or add weight to the assembly and allow the epoxy to cure completely. Saturate the 1/4' (6 mm) holes with thin CA. Place the assembly onto the firewall and line up the centering marks on the mount and the firewall.
to install your servo properly using the same procedures that you have installed the tank so the vent tube inside the tank that you used previously. Is pointing upward. Notice in the above photograph that the former has been designed to allow rubber bands to hold the We recommend that prior to finalizing your engine mounting, tank in place.
Repeat this process at the locations of the other five cowl mounting blocks. Mount the cowl using six #2 x 1/2'(13 mm) Phillips head screws and six #2 flat washers. After the epoxy has cured cut a piece of a file folder, ❏. Place the drive washer and the propeller nut onto the 2. To mount the receiver we used a Great Planes drive shaft.

Make sure that you can access the screws and that it is placed to avoid the spars and formers in this area. Install the Flying Wires NOTE:The flying wires included with the Pitts Special ARF are not functional or required for structural integrity. Use the photos above as a reference guide in assembling the flying wires. We are going to start by making the left side flying wires.
When you are finished installing the flying wires on the left side of the model, repeat the process to make the flying wires on the right side. Locate three 4-40 x 5/8' (15.9 mm) Phillips Head Machine Screws, three 4-40 stop nuts, and eight 70-degree metal brackets as shown in the photograph. Finishing Touches ❏ 7. Mount the brackets at the bottom of the fuselage, with the 'bend' to the bottom as shown in the photograph above, use two #4 x 1/2' Phillips head wood screws to attach the brackets using the procedure described on page 8. GET THE MODEL READY TO FLY NOTE: SOME MODELERS LIKE TO HAVE A BIT MORE TECHNICAL INFORMATION FOR THEIR MODELS THAN OTHERS. FOR THOSE WHO DO, THE WING INCIDENCE OF BOTH THE TOP AND BOTTOM WING IS 0 DEGREES WHEN THE STAB IS SET AT 0 DEGREES. THE ENGINE THRUST IS ALSO BUILT-IN AT 0 DEGREES DOWN AND 2 DEGREES RIGHT.
Flying your model at these throws will provide you with the greatest chance for successful first flights. If, after you have become accustomed to the way the Pitts Special ARF flies, you would like to change the throws to suit your taste, that is ❏.

This requirement applies to all glow/gas ignition engines regardless of size. Since the Great Planes Pitts Special S2S ARF qualifies Section 6.0: RADIO REQUIREMENTS as a “giant scale” model and is therefore eligible to fly in IMAA events, we’ve printed excerpts from the IMAA. Generally, it is recommended that no attempt should be made to fly a radio controlled model aircraft with a gasoline engine in which the model aircraft weight would exceed During the last few moments of preparation your mind twelve (12) pounds (underpowered) per cubic inch of may be elsewhere anticipating the excitement of your engine displacement, or be less than five (5) pounds first flight.
