RC Helicopters
From micro helis to 700-class machines, AltimeterThree captures your flight envelope. Track altitude during hovering practice, aerobatic routines, and everything in between.
Built for 3D flying
RC helicopters demand precision control and generate intense accelerations during aerobatic maneuvers. AltimeterThree's 3-axis accelerometer captures up to 24G, giving you data on your most aggressive flying.
- Maximum and minimum altitude recording
- 3-axis acceleration data for maneuver analysis
- Complete altitude profile graph
- Flight duration with auto-detection
- Launch location shown on a map
- Export to spreadsheet for post-flight review
Flight modes for every style
Whether you're practicing smooth scale flying or pushing the limits with 3D aerobatics, AltimeterThree adapts to your style.
Hover practice
See your altitude stability during hover practice sessions.
3D aerobatics
Acceleration data captures the intensity of your tic-tocs, funnels, and smack downs.
Scale flying
Track smooth altitude profiles that match real helicopter flight patterns.
Lightweight and rugged
At just 10.4 grams, AltimeterThree won't affect your helicopter's balance. Mount it in the fuselage or under the canopy — the barometric sensor works through small venting holes or the natural gaps in most heli frames.
- Compact size — 49 × 18 × 14.5 mm fits anywhere
- Crash-resistant — Rugged ABS construction
- Vibration tolerant — Designed for high-vibration environments
- USB rechargeable — No battery swaps needed
