Sure, in the background I was thinking how to improve our F3B stuff. Slowly getting to be friend with my Viking. Our main goal was launch performance-endless process. We'v got already some results; out from 25 launches average height 279m for me and from another 25 launches 269m for my friend Jindra, all launches included just one by one, no mercy. Wind was from 6-3m/s (15:00-19:00), we were not replacing launch batteries on our four winches at all during whole day (we had no spare ones). I also logged the HIGHEST launch I'v ever seen on my PC; 343m and from zooming 171m! Do you have higher one? ;-) Data for A2 analysis utility
