F3B Sighting System
F3B Sighting System
Glauco Lago: Since the contest yesterday was unexpectedly short, I had to go back again and fly a little more but this time to practice a little more F3B.
At least I found out why I like F3B, it is the only thing Chris can't beat me. Well, that and number of kids but that one he still has a chance to catch up.
Main reason to fly today was to test my new wireless base B sound device along a few gizmos I decided to add. That is what I've beem working lattely and I'm happy to report it works most of the time. In brief it is a setup where the person standing at base B (150 meters away from me) pushes a button and a horn at base A tells me my plane has flow by base B. I also added a stopwatch and a counter, both foot switch operated so I can time the speed runs and count the laps too.
As a helper at base B was my lovely teenager daughter which was thrilled to wake up at 7AM and spent a bit of time doing nothing. But must say she did a fantastic job, the same for Gabriel who couldn't wait to spend another day at the sod farm.
It was supposed to be windy and the forecast got it right. It should be light early in the morning but moving two kids from home early Sunday and setting up two winches, two sighting devices plus everything else takes a long time so when all was ready it was about 9:30. Those F3B planes penetrate well so wind isn't much a problem but I'm trying to get the slow 180° turns down to a science but the wind wasn't helping.
Later in the morning I decided to remove one of the shells of a winch so the diameter of the drum is smaller, this is done to fly with some wind. But the line I had was 1.1 mm which is a bit too thin for wind and ballast. Decided to launch anyway, hooked up left for the wind direction and half way the line broke. Really interesting, the line in the drum fused to itself and that is why it broke, I can still pull the line from the drum but it is somewhat stuck to each other.
So with one winch, wind, the sun right in front of me and two bored kids I decided to quit and pack all that gear. Would love if more people would fly B, at least I could share the setup time. But it was fun and I can't wait to try my new to me Freestyler 3 that should arrive this week. It is a scary fast plane so it should be interesting.
