Do you take advantage of Butterfly calculations in the Ultimate? (i.e. do you feed this latter with Butterfly outputs? such as vario, baro alt, wind) Is the wind in the Butterfly also quickly updated and accurate (as far as one can judge), thanks to all the sensors it has? especially in straight flight Adrien, I don't use the butterfly vario data yet, I am waiting for the Data Module from Butterfly. The Butterfly is standalone at this point. I use PowerFlarm - LX1606 - Ultimate Le. The winds calculated with the SeeYou PNA on the Ultimate Le are very similar to the Butterfly Vario. The winds of both in my opinion are quick and accurate. I don't see any significant differences. The buad rate for the PowerFlarm to LX1606 to Ultimate is 38400. I think this is important for wind calculations, but I am not sure. Any baud rate teckies out there? Richard www.craggyaero.com Richard, Do any of the instruments in your panel give current wind direction and velocity while flying straight? Or, are they all requiring circling in thermal drift to calculate wind? -Jim I believe the PowerFlarm, LX Navigation 1606 Ultimate give winds if you make a slight course change. the Butterfly I believe straight because it has a compass. I have not noticed much difference with either set of instruments. Richard www.craggyaero.com Thanks. I have a PowerFlarm and it does not give any wind info.

Jim,

You need a PowerFlarm with a vario like the LX1606 or V7 to get wind information. The PowerFlarm or LX1606 alone will not give winds. PowerFlarm sends GPS & Flarm data in the NMEA streat to the vario the vario adds vario sentences to the stream and you software SeeYou Mobile etc will calculate winds.

The ButterFly varo alone will give winds.

Thanks! I'm keeping my eye on the Butterfly as a possible replacement for the VP-4E and Colibri that I currently have. If the old Peschges ever quits working or if my club decides to equip all the gliders with PowerFLARM it looks like a good possibility for a system that will do all that the old equipment did and adds the FLARM capability without taking up too much panel space.

I don't need the tasking capability as my flights are all just flown in "make it up as you go along and go where it looks interesting" mode. As far as I'm concerned, flying a "task" sounds too much like work!

What would it be like to use if you only had the Butterfly and PowerFLARM brick? When they get the logger certified would that basic combo provide Flarm, logging, vario, glide, wind and ground speed and selection of various turnpoints?



The equipment you suggested would be fine for the items you listed. The issues is that there is only go to turnpoints and no tasking. You need a display with software for the tasking.
