F5J Xplorer2 4000 glider used for AltimeterThree testing
Aris Kosmides' F5J Xplorer2 4000 glider in Thessaloniki, Greece — used to verify AltimeterThree precision against FAI-approved equipment

Precision for competition and practice

The glider mode in AltimeterThree was designed with input from serious competition pilots. Whether you're practicing for F5J events or just want to track your thermal flights, you get the data you need.

Real-world precision verified

AltimeterThree has been tested against FAI-approved altimeters in competition conditions.

"During my glider flights the maximum difference between AltimeterThree and my FAI-approved ALTMR2 was 80 cm, and the average difference was 50 cm. I believe this accuracy is excellent for RC use."
— Aris Kosmides, RC flyer, Thessaloniki, Greece

In extensive testing on F5J Xplorer2 4000 gliders, flights ranging from 195 to 388 meters showed consistent precision that rivals dedicated competition equipment — in a package weighing just 10.4 grams.
