LoLo- (10/06/02) |

|
Introduction About this device I was dreaming off for a long time. LoLo (Lomcovak's Logger ;-) is called this clever piece of harware and allows you to log altitude up to 9 hours!! There are many possible manners of utilization but take a while and look for what I 'm using it... |

|
You can connect LoLo to free receiver input or just use standalone battery, it is up to you. Current consumption is virtually zero i.e. 15-17mA |

Bellow you can see one of my first altitude logs. LoLo was in my midsize hotliner Optima II. Wing span 1250mm (49" ), 12 cells Sanyo 1250SCR, brushless Phasor 30-3, prop Aeronaut CamCarbon 10x6. Sure I was happy that design is finished and my intention was to test it hard. In forth climbing you can see I reached height 536m. I had BIG BIG problems to control such small airplain in this altitude... |

But the main reason why I speak about LoLo are pure silent flight disciplines; F3B, F3J and F3F (my interest). Here I found LoLo's services invaluable. Bellow you can see forexample start analysis of my NewSting. I was tunning trailing edge deflection. It was evident that too much flaps and ailerons doesn't work. Optimum was somewhere nearby 6-7mm trailing edge, interesting. Good to know. |

A bit more detailed view to one start. Sampling rate of altimeter was switched to 0.1s. Good for start analysis. |
||||
|
||||
|
...and even more zooming in to zooming |
||||
|

|
Also interesting graph. It's speed record. Note peaks on turning bases A or B (red arrows). There is quite interesting "ballast" product of pressure sensor. You can see when I was turning while G was so high that sensor produced altitude increase which marked turning. Sure (or hopefully;-) I was heading down when turning, not up... |
