Auggie's RC Heli Toolbox, designed by and for RC Helicopter pilots it's a courtesy of AEON RC. Designed by RC Helicopter pilots. Includes AEON info pages and access to the AEON site. It also includes an innovative interactive head speed calculator, an Ultra High precision Pitch Gauge, 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 helicopter or airplane 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 AEON RC manuals directory to easily find your AEON Product 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 helicopter/airplane 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. We hope you enjoy this free App courtesy of the International AEON RC. ## Key features - Interactive head speed calculator - Ultra-high precision pitch gauge - GPS altitude and speed recorder - Talking flight timer - Units converter - Access to AEON RC manuals ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/rc-heli-toolbox/id963092346/reviews.md ### 1/5 — Please update the cell voltage *2024-08-20* For the headspeed calculator, the voltage should be adjustable or made to 3.7v or 3.8 as opposed to 4.2v Please and thank you. ### 5/5 — Gear ratio *2023-03-31* Easiest way to calculate gear ratio and motor size.
