My first heli: Humming 20 from 1978

Fix pitch. Used Fuji 25 engine. No cooling fan. Used hugh heat sink to cool the engine down. Wood frame with alumimum tail boom & skid. Tail rotor, tail fins were made of balsa wood. No indication in manual on the pitch angle, just twist the nylon block on rotor header to whatever you feel comfortable with. Tail gear was exposed - to dust and everything. Note the air foil, it used flat bottom airfoil.

JR heli radio from 78-79 for the Humming 20

This all metal helicopter radio was from JR back in 78-79. It didn't have any dual rate, mixing or servo reverse. It was on 27MHz FM (an advance feature at that time). The top of the radio has 4 special knobs for the ATS system and a switch to turn the system on/off. The knobs control the response of the rudder servo with respect to the rate of change of the throttle. How fast the rudder response and the magnitude of the defection of the rudder servo - all done on the trasmitter (without micro processor/computer), no gyro.
The gimbal stick.

Well, it touchs the water
surface, come to a stop
instantly and floats instead.
