ParkZone Sukhoi Su-26m
The ParkZone™ Sukhoi Su-26m is a 4-channel micro airplane that is capable of performing aerobatics and mild 3D indoors, or outdoors in calm conditions. It is only available as a BNF kit that includes the plane, charger, AA batteries, and a 110 mAh lipo, and began shipping in April 2009.
The Sukhoi is constructed of lightweight foam with carbon fiber pushrods and wire landing gear. It has a 4-channel AR6400 brick and an additional external servo used to control the ailerons. The brick has a 3-pin motor plug that can be used to control an external brushless ESC. It also includes ports for channel 5 (or mini x-port) and channel 6 (reverse aileron or aux). The receiver will bind to any 2.4GHz DSM2 radio, though the DX5e is recommended as the minimum.
On September 1, 2009, a Sukhoi flown by an unknown pilot delayed the top of the sixth inning of a baseball game between the Los Angeles Dodgers and Arizona Diamondbacks at Dodger Stadium. The plane eventually crashed near the Diamondbacks' dugout; Diamondbacks utility infielder Augie Ojeda picked up the model and destroyed it so that play could resume.

Center of Gravity
The majority of modifications revolve around moving the center of gravity (COG) beyond what is permitted in stock configuration. From the factory almost all Sukhois are nose heavy and can be very difficult to balance even with the lipo placed at the most rearward position. Various modifications are available to remedy this. The easiest fix is to tape a paperclip or other weight under the tail. This adds weight however, and should be used as a temporary fix. Another common method is to cut away the foam at the back of the battery slot to allow the lipo to be placed further rearward. Longer battery leads are sometimes also installed. Some have even run the wires inside the fuselage allowing a separate battery slot to be cut in the tail.
There is often an excess of glue on the motor mount at the front of the plane that can be carefully removed to help the balance.
The Parkzone Sukhoi should have a center of gravity roughly between 29mm and 36mm behind the leading edge of the wing, depending on your skill and desired flight characteristics. Most people consider it nose heavy at 29mm. 32mm should allow for normal, well-balanced flight, while a center of gravity of 36mm and beyond can be used for advanced aerobatics.
