The technology is here, so where can I get a variometer for my glider,
that gives me feedback? (without big bucks and rocket science)

About 10 years ago I found a radiosonde weather balloon, much the worse
for salt water, but the little biddy circuit board worked--when I hooked it to
a battery, it generated a tone of the FM band, that would rise in pitch if I
held the sensor wire in my fingers----seems to me there was the Ace Thermal Sniffer,
but was tempermental

Most (read: all) of the model oriented Vario's run upwards of $300 (Piccolario is one of the better ones) - with voice output add about 150.  It is almost cheaper to buy a new radio with telemetry and the corresponding sensor.

I just got the Eagle Tree Altimeter sensor (V4) that CAN be used with the E-logger or as a "stand-alone" unit.  No direct feedback unless the Seagull telemetry module is added (for another 350 bucks), so , to my knowledge, there is no "inexpensive" vario that also works well.

We've got a guy in our club who will stand next to you and provide a rising and falling tone, total energy compensated, gratis. I doubt he's very linear, though.

Thanks, good to know.

But it looks like Pit is correct.

Cut it twice and it's still too short!

I have a piccolario surplus to requirements, now that I have the MPX Profi and telemetry sensors.
Also comes with 2x Allen walkie talkie receivers, dedicated charger and ear pieces.
Looking for £200 - a lot less than new or alternatives plus postage.

PM me if you are interested and I can see about a postage price.

Cheers John

Taranis has telemetry capability with cheap on-board altimeters. I believe there are DSM2/X based systems as well. Again, pretty affordable. I'd recommend these options over any of the others presented simply because the cost is an order of magnitude lower, and they're quite easy to use.

FrSky (the maker of the Taranis) seems to be becoming a reliable system.  It's relatively low "visibility" probably stems from misplaced distrust of "cheap" high-tech articles.  With the positive reviews of the FrSky systems, I hope they are able to keep their pricing policies.

However, their newest offering in the "Pro" class that I had my hands on at the Jet Power trade expo this year REALLY impressed me...

Been flying Fr-Sky for 2 years. Great value and always has been a reliable system! Much more so than Futaba. (Futaba has been great with their service in the past years)! And the programing architecture of Open TX is close to that of we in the USA lost when Multiplex dropped the USA market.
Not sure the Horus is worth the power drain on the TX battery. But for $550 it is a giant killer!

Another good aftermarket telemetry system is that from IISI (http://www.iisi-rc.com/IISI-RC/Home.html) out of Switzerland.  Transmitters for the system are available in various capacities (30-200 Amp) and the 'Cockpit V2' receiver is a very nice and well rounded unit - but rather pricey.  The altimeter/vario sensor must be purchased separately.  Still an outlay of over $200.

I have one of these systems with the adequate V1 receiver (no schnick-schnacks) and am quite happy with it (but I WILL be purchasing the Cockpit V2!).

Has anyone tried the Hitech telemetry system variometer?  Providing you have a Hitech transmitter and receiver, the variometer and "Telemetry Sensor Station HTS-SS Advance" are available from Tower Hobby for about $50 + shipping.
