LOLO5 under test

Thanks to my good friends I had chance to measure my LOLO5 logger in calibrated pressure chamber. We were “flying” more than 60 minutes up to 4000meters ( more than 13.000 ft). Although LOLO5 was designed for RC model users i.e. approx. up to 1000meters (3.300 ft), error in 4000meters was 6,4% (254m/833ft). Bellow you can see altitude log, deviation table and measuring devices configuration.

During measurement and changing flying level I had also chance to check accuracy and sensitivity of LOLO5 vario part. Deviation was about +/- 0,1m/s. All in all I would sum up-very good device. [continue]

Crowded

Today I fly my Tanga (Bretamodel.cz) in following configuration:

LOLO5; records altitude, voltage, flap servo (JR/Graupner Nr.6)
SPELO5; records speed (IAS-Prandtl probe), voltage, elevator servo (JR/Graupner Nr.3)
TENZO; records line tension
JETI Duplex R6 Receiver (2,4GHz)

All three devices are time synchronized, some data are seen on-line on my transmitter via JETI Duplex downlink. There isn’t too much space, is it? Very soon I will add GPS logger and 220Volt plug (grin).
