E-flite Ultrastick 25 OverviewThis plane is based on the hugely popular Hangar 9® Ultra Sticks and offers
the same excellent flying characteristics, but with electric power rather than glow.
No other .25-size Stick on the market comes out of the box with so much ready to go. The airframe is fully built and covered, the steerable tailwheel is factory-installed and the control surfaces are prehinged. That means less assembly time and more flying time for the modeler.
It’s also set up to accept two different brushless applications, giving consumers more options to fit into their personal preferences. Plus, the wing is designed for optional quad-flap configuration, and separately purchased fiberglass floats can be added for fun touch-and-go’s at the lake.

Ultrastick 25 ARF BulletinsImportant Note
We have found, during continued flight testing, the possibility of a rx/servo current overload to the BEC in the speed control, causing the motor and radio to shut down in flight. This has typically happened on extreme high temperature days with continuous extreme flight control inputs. Most speed controls on the market today are designed for use with 4 sub-micro servos with relatively low current draw, like the E-flite S75. The newer sub-micro digital servos, as well as most micro and mini servos, have a higher current draw and can cause a BEC to shut down due to high temperatures. In order to provide the most reliable product, E-flite recommends the use of a separate BEC (like the Ultimate BEC), or receiver pack and switch using the following items to ensure trouble-free operation:
(1) Expert 720mAh Ni-MH 4.8V receiver battery
(2) Expert Standard Switch
Use these items to power the receiver and servos after disabling the BEC on the ESC (by following the instructions included with the ESC).
E-flite does NOT recommend using the speed controller’s BEC in the applications described above. More Ultrastick 25 Photos with optional float kit
