The FrSky High Precision Variometer measures the rate of change of altitude by detecting the change in air pressure (static pressure) as altitude changes. When used with the FrSky Taranis transmitter you can create a true glider vario with tones that indicate lift and sink, a feature usually costing several hundred dollars for other radio systems.
I have used this vario for F5J glider practice, I’ve set the Taranis TX and D4R-II RX to give me a verbal readout of my altitude at 30 seconds and 40 seconds after throttle up giving me an accurate idea of what a model is capable of on launch. In vario mode, I get a good read of what thermal activity is like on the day. So far it has done everything I’ve asked it to do accurately.
Next test is to set the Taranis to reduce throttle to 25% when reaching maximum allowable legal altitude for our field, with, a verbal warning to let you know you have reached max altitude.
A great product Aloft Hobbies, many thanks.
I have this installed in my Radian and it works great. Affordable as well. Recommended.
I use this with my old JR 8103, upgraded with a Frsky module, FLD2 display and D4RII rx. Setup wasn't too difficult but did take a little research on the web as the instructions with the frsky products are pretty minimal.
I'm fairly new to gliders and fly on my own. This unit answers 2 basic questions when you're learning to soar: how high is my glider, and was that lift I just flew through? I'm finding with this setup there's a bit of lag between the time you enter some lift and the unit starts to signal but in some ways that helps me as I'm starting to recognize how the plane reacts first, then the beeps confirm it.
I highly recommend this as a training tool for beginning sailplane pilots.
It only took me like 30 seconds to install in my glider, and just a few minutes to program the telemetry display and a switch to turn the vario tones off and on and it's working like a champ.
Can't wait to take it out to the field and fly it tomorrow, I think I'm going to fall in love with my glider again!!!
I love this unit, I threw it in my Radian Pro along with a Lipo Sensor and set it up so I can get every piece of info I need read back to me without taking my eyes off my glider. Really helps when you are "specking out" at (for that size glider) about 1200ft. I left the Vario Settings on the stock settings but did put it on a switch, (I don't always fly with an ear bud so it might get annoying to some folks) and I don't need it all the time. It is nice though to be able to tell what is going on, I caught the beginning of what could have been a wing twister of a dive when I lost sight of the aircraft for a second. The Vario's pitch told me I was in a steep dive even when I could not at that moment see it. Very nice to have and the altimeter reading is great to play when your standing next to somebody who says Radian Pro's aren't worth owning....
Sometimes I daisy chain my GPS module into it as well, to get speed readouts etc. My club is just now starting to hear about this system, and are blown away by the system, the features and the price.
I must confess I have had mixed experiences with previous vario version, but this one is a 21st century leap forward...
Coupled with a Taranis and latest OpenTx 2.0,1... I have rediscoved similar feelings I had when I was soaring the real-sized gliders...
No more approximation in the thermal , the bip-bip confirms you are centered and the vocal altimeter on the taranis gives your score every 10 seconds....
Exactly what I was looking for... Thanks Fr-Sky and Thanks Aloft-Hobbies for first class service...
Reordering another one for my larger glider and some other goodies to go full s-bus (good bye naughty hub :) )
I'm coming from a Pitlab audio vario which has very nice audio comparable to full scale variometers.
The Frksy unit is pretty jumpy and hard to decipher. However the audio altitude readout is excellent and accurate so a software update may be able to to turn this into a very good unit
Video of audio:
(Note from Aloft - Yes, new Taranis firmware will offer many new sound options for the Vario! 4/8/2014)
Very accurate, and fast,used with a total energy probe setup.
What an amazing device. I'm just starting the glider thing, so imagine having voice call outs of altitude and vertical speed, up or down, and the vario tone!
Like all frsky products, you need to ask others how best to use it.
When used with the FrSky Taranis radio it sends the vario tone and the altitude down to the radio over the telemetry channel. I just paid $300 not too long ago for a SkyMelody vario and this one does everything it can do.
