The Flymaster B1 is the most recent flight instrument from Flymaster Avionics. It is a Variometer targeted at soaring flight pilots who do not require integrated navigation features.

The B1 is based on Flymaster F1’s proven technology, providing the pilot with an extremely sensitive and accurate variometer, which will detect even the weakest of thermals, giving you the edge above the rest of the gaggle.

Amongst many features the B1 has a real time altitude plotter, 3 altimeters. It can store over 1600 flight log records, with altitude logs on a second by second basis. It also boasts of a high resolution display with excellent viewing contrast and an optional backlight. Another unique feature is an RF interface built into the B1, giving it the capability of connecting several wireless probes simultaneously.

To top it all, B1 has a built-in modern high capacity lithium ion polymer battery, which powers it for dozens of hours.

version 1.43
1) Bug resolved that was causing a diagnostic failure code, and strange behavior on flight log visualization.


version 1.42
1) Fixed issue which could cause some devices to drain battery in shutdown mode.

version 1.41
1) Several bug corrections.

version 1.40
1) New vario scale, now displays a full 0 to 10m/s up and 0 to -10m/s down, on the left and right sides, bullets also mark the max climb and sink.
2) Includes functions to work with the Paramotor M1 module.
3) Versions 36~39 several improvements were made to the battery charging process.

version 1.35
1) In previous versions changing altitude units from meters to feet implied changing vario units from meters per second, to feet per minute, a new setting has been added that allow moving selecting meter per second or feet per min units in the varios separately from the altitude meters/feet unit.
2) Ability to sync with the PC using the B1 Flight Suite added.
3) Memory optimization.
4) The introduction of the QNH value is now possible.
5) The Algorithm used to determine the altitude was optimized, more accurate values are now obtain.
6) The change of the sound volume level as been remove from the flight screen, only the possibility to mute/un-mute remain. A new option as been added to select the sound level.
6) Several minor improvements as been added.

version 1.18
1) In previous versions changing altitude units from meters to feet implied changing temperature units from celcius to farenheit, a new setting has been added that
allow moving selecting celcius or farenheit units separetly from the altitude meters/feet unit.
2) Updating firmware can now be done from with in the menus, this simplifies the procedure. The previous method of pushing the reset button is still available.
3) Date and time where not updated while the date/time option in the menu was selected, this has been corrected.


version 1.17
1) Added new option "Auto Silent" in the "Advances Features", when on this option keeps the buzzer silent until flight begins (ie, altitude variation of +-5 meters)
2) Fixed a bug where the buzzer was not complying to the set value.
3) Spanish localization added.
