Syma S026 CH-47 Chinook ouf of the box

Just got a Syma S026 CH-47 Chinook off ebay – nice little machine.

Now if it only had a gyro and i could fly it with my 2801 Pro TX. So i removed the IR receiver and put a Walkera 5G6 RX2402 into the heli. Motors hooked up in parallel. Now i have a nice little submicro Chinook heli that has a gyro.

Only two channels for now, forward speed is set by COG adjustment. Replaced the stock battery, both 240 and 400mAh Zippys work well. Here is a little video.

The lady is flying. 100mAh lipo, Walkera 5G6 4-1, servoboard mod proportional tailmotor for 3rd channel. 6:30 flighttime. Based on the famous IR Toy Airwolf helicopter.  Build log here.

Just did the first testflights with the Airwolf coax helicopter – made from the well know RC toy heli, the IR, 3Ch Airwolf.

inside look: Airwolf 3 Ch 2.4GHz gyro-ed

The electronics were removed and replaced by a Walkera 5G6  4 in 1 (RX2402) which has 2 brushed motor outputs, 2 servo outputs and an onboard gyro. The 4 in 1 goes into the body quite nicely – only little cutting was necessary.
The heli is now powered by a 50mAh Zippy lipo – maybe a 70mAh or even 110mAh will also do.
Because of a broken rotorblade tip i had to cut the blades back – not good, because lift is decreased significantly – now im waiting for new blades.

The third channel is used to controll the vertical tailrotor. This rotor achieves forwars and backward flying. The motor is powered via a servo board (PCB) which instead of driving the servo motor drives the tailmotor.

Just a test of posting some images…
