RC Heli Calc app for iPhone and iPad

The large keypad allows for accurate input while the sliders allow for quick and easy what if scenarios and analysis.

RC Heli Calc is a set of four calculators for determining, estimating, and analyzing the Gear Ratios, Motor Kilovolt, Lipo Cells in Series, and Head Speed configurations on remote controlled helicopters. The calculator provides all of the information necessary to assist in setting up an electronic speed controller (ESC), including a throttle curve slider for transmitter settings. All electric calculations are based on an efficiency of 89 percent for a more accurate "real life" calculation.

The Head Speed calculator works with both one and two stage helicopters.

The one stage calculator includes a find feature that contains a data base of over 80 different helicopters, including popular helicopters that are no longer in production. Eliminating the need to count the individual teeth on the main gear.

The two stage multi-gear calculator is designed for helicopters that use a set of keyed gears between the main gear and the pinion. All four gear counts can be entered directly, thus there is no need to use an "estimated" number.

The keypad allows for precise input of all and any variable which in turn recalculates and updates all other variables automatically.

Customizing your electric helicopter, ESC, and transmitter are now a snap. Analyzing new configurations (what if analysis) is as easy as moving a slider or keying in a number. The program analyzes the gearing combination and uses the number of cells in series on your "LIPO" and the motors kilovolts to configure and determine the head speed. The throttle slider on the calculator can be matched to the throttle curve on your transmitter for quick and easy set ups, every time.

Whether you are new to RC Helicopters or customizing an existing Heli. RC Heli Calc is a must have, essential tool.
