Norbert Habe, author of many HN airfoils, big silent flight guru, died April 11, 2012. I remember long discussions at F3F Donovaly (Slovakia) with Norbert. He was always ready to help or dispute any aspect of model flying. R.I.P.

LOLO5 firmware update 2.93

As I mentioned in news, LOLO5 production is stopped (sold out) and I started to work on LOLO6. Prototypes should be ready within 1-2 months. Sure, support for LOLO5 is running in normal manner. I bring you new firmware update. Please, follow instructions. [continue]

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]

How to fine tune your airplain using LOLO5 analysis?

Starting right now there is available new generation LOLO5 recorder. Step by step I’m adding some examples from real life. Now you can read about flap servo record and how to understand it.
