Ray's HeliTech Volume 1 2 and 3

TX THEORY, BENCH SETUP, & FLIGHT TRIMMING

VOLUME 1: Transmitter Theory and Setup (1 hr. 43 min.; 47 scenes)

This disk goes through every item in the transmitter menu. After an overview of theory for each menu item, the “armchair” settings are punched into the transmitter. These are the points, curves, and program mixes that can be programmed before you ever work with the helicopter.

VOLUME 2: Helicopter Bench Setup (1 hr. 7 min.; 26 scenes)

We fine-tune the linkage lengths, set the servo endpoints, and set up the cyclic, collective pitch, throttle, and gyro.

Scenes 10-18: Cyclic > Throttle Mix Checks · The 90% Throttle Rule · Gyro Rate vs. Heading Hold Checks · Electronic vs. Mechanical Gyro Gain · Tail Rotor Pushrod Setup · Tail Rotor Pitch Theory · Tail Rotor Servo Direction · Gyro Direction · Gyro Authority Theory

Scenes 19-26: Collective Pitch Setup Basics · Checking Collective Pitch Range · Pitch: Normal Flight Mode · Pitch: Flight Modes 1 & 2 · Pitch: Throttle Hold · The Advantage of a Non-Driven T/R · Tail Rotor Pitch for Autos · Final Pitch Curve Checks

VOLUME 3: Helicopter Flight Trimming (55 min.; 26 scenes)

In three tanks of fuel, we take a helicopter that’s never been flown and go through all the trimming steps necessary to make it a finely tuned 3D machine! The limits will be your flying skill, not the helicopter’s flight capability!
