Anyone got any in flight experience of the LX Nav V7 or the Butterfly vario? I love the features of the Butterfly but looking at YouTube clips it seems to be way too sensitive?? Any alternatives? Thanks Chris

Chris,

I have flown with both the LX Navigation LX1606, LXNAV V7 and the Butterfly Vario. Probably about 30 hours.

This YouTube shows an LX1606 and the Butterfly Vario. Hard to see the LX1606 in the YouTube.

The ButterFly Vario is the only display I have ever seen that is as good as my Ultimate Le in the sun.

I don't have a YouTube vs the V7.

I also found the SC a little sensitive on the Butterfly and emailed them about the issue last fall. They agreed and the latest Firmware of the Butterfly added a compensation menu item for the SC error filter. So you can adjust to what you desire. The compensation values in all the instruments should be set to smooth the performance of the vario and in my opinion don't really correspond to seconds.

I tuned the Butterfly Varo using compensation values to exactly match the LX1606 and V7. The V7 and Butterfly have more features than the LX1606. I have not had a chance to test the Butterfly with the latest firmware and the SC compensation, but I am confident it will work well. The V7 and Butterfly also have flarm screens.

All three varios in my opinion are an great improvement over CAI 302 technology.

They also allow PowerFlarm integration with out a multiplexer and operate at much higher baud rates that the 302.

I have all in stock.
