Pare che il controllo qualità sia piuttosto scadente:

“Bought one of these to use with my Multiplex M Link system, unfortunately the 1st one would stop randomly, I sent it back to Hyperflight and they not only had a new one back to me straight away, but also copied me on correspondence with the factory re the faulty unit. Replacement unit has been fine and links well with M Link telemetry system although speed is incorrect in the telemetry readout, but reads correctly on the data explorer, Aerobtec are aware of this and there should be a firmware fix soon.”

Great tool
This is a great little product! Only tried it a few times but the GPS and altimeter instead of ”just” altimeter fits my needs perfect. After your flying session searching for thermals you can not only see how much lift (or sink) you got but also where you were when it happened! Ideal in trying to learn more about the geographic aspect of the magic thermals. Before I thought it would be really nice to have this kind of information, now I will not fly without it!

Very Neat
Bought one of these to use with my Multiplex M Link system, unfortunately the 1st one would stop randomly, I sent it back to Hyperflight and they not only had a new one back to me straight away, but also copied me on correspondence with the factory re the faulty unit. Replacement unit has been fine and links well with M Link telemetry system although speed is incorrect in the telemetry readout, but reads correctly on the data explorer, Aerobtec are aware of this and there should be a firmware fix soon. Data is very easy to download and analyse. Note the addresses on the M Link system are fixed and as follows
2 - Altitude [m]
3 - Vario [m/s]
4 - Ground Speed [km/h]
5 - Distance from first fix [km]
6 - Bearing angle [°]
7 - Maximal altitude [m]
8 - Odometer [km]
9 - Maximal distance form start [m]
10 - Temperature v [°C]

Overall a great little unit.

As usual fast delivery!

i had a bit of a struggle to get the gps working via the futaba telemetry converter but that was caused by me and not the GPS.. Read the manual carefully and remember that the module needs a power source when you connect the gps to the bus port to register!

speed/distance/altitude and vario is visible on the transmitter, how it works in real life will be clear tomorrow
