The IRCHA RC Heli Toolbox, designed by and for RC Helicopter pilots, and as everything from IRCHA it's a courtesy of IRCHA volunteers. Designed by RC Helicopter pilots. Includes IRCHA info pages and access to the IRCHA site as well as event competition voting and Push notification of events happening inside the Jamboree to help you keep track of the Jamboree schedule. It also includes an innovative interactive head speed calculator, an Ultra High precision Pitch Gauge, a Flappy Heli Game with Apple Game Center access for Leader score tracking, a talking Flight Timer, a GPS based Altitude and speed Recorder in case you have an old iPhone that you want to strap to your heli/plane and find out what the maximum speed was or to calculate the air density for adjusting collective pitch in high altitudes, a Units Converter to help conversion between measuring units, Access to the IRCHA heli manuals directory to easily find your helicopter manuals and your tail servo speeds and frame rates.

Below are the sections explained:

Interactive Head Speed Calculator section calculates head speeds interactively by sliding the dots and finding the desired head speed. It uses both one and two stages (2 gear and 4 gear).

Ultra-High Precision Pitch Gauge section is used to measure the incidence angle taking advantage of the very precise accelerometers present in today’s phones and using the high-power processor present in the phone to do high-speed digital signal processing of the accelerator’s signals. The get pitch gauge mount button will take you to the page of the Ultra-High precision Pitch Gage phone holder.

Altitude and Max Speed Recorder section is used to show the altitude of the flying field so that pitch changes can be made accordingly and if you have an old small phone you can strap it to your heli and record the maximum speed it does while flying.

Units Converter section is used to make unit conversions in the most commonly used units in the RC Heli Hobby.

Talking Flight Timer section is used for pilots that either don’t have timers or who want a more feature-rich timer for the flights.

Flappy Heli Game. Touching the screen, the heli jumps gaining altitude and drops when the screen is not touched while the pillars advance allowing you to adjust the height to pass the pillar.

High Scores can be stored in Apple’s game center servers for record keeping.
RC Heli Manuals section takes you to the IRCHA page on RC Heli Manuals.
