iOS app
Set up any RC model. Balanced to the millimetre.
RC Model Utility brings unlimited control-surface configuration, every tail layout, and live centre-of-gravity readings into one workspace on your iPhone.

A toolkit for every airframe
From a simple trainer to a full-house aerobat or a V-tail glider, RC Model Utility adapts to your model — not the other way around.
Unlimited control surfaces
Add as many ailerons, elevators, rudders, flaps and flaperons as your model needs. Assign a channel, throws, expo and mixes to each surface.
Any tail configuration
Conventional, V-tail, X-tail or twin-boom — choose a layout and the app handles the ruddervator and elevon mixing for you.
Live CG measurement
Connect a compatible centre-of-gravity measuring device over its API and read your CG in real time, with a target range saved per model.
Mixes, rates & expo
Dial in dual rates, exponential and cross-surface mixes, then preview the deflection before you ever leave the bench.
Model library
Store every aircraft as a profile. Switch setups in seconds and keep trims, mixes and CG targets together.
Export & share
Back up a model or share a proven setup with a friend as a single file.

Built around your centre of gravity
Get the balance right and everything else follows. RC Model Utility talks directly to a connected CG measuring device, so you read your true centre of gravity instead of guessing.
- Live CG readout straight from the scale’s API
- A target band saved for each model — green means go
- Nose, tail and total weights at a glance
- Log every measurement against the airframe
Configure surfaces and tail your way
Build the airframe once and the app keeps every channel, mix and throw in order. Switch a tail from conventional to V-tail and the mixing updates automatically.


“I set up a new V-tail glider in minutes and the CG was spot-on for the maiden flight.”
