Have him already at -6 ° C tested without problems.
My maximum distance to my Graupner MX-12 was times 1500 meters !!!
And without missing a second of losing contact. Telemetry is quickly and accurately (of course you need appropriate sensors such as the Vario altimeter of Graupner is still quite cheap)
Even at high temperatures, no difficulty (over 55 ° C receiver Temp.)
Overall, in conjunction with my MX-12 and for example the Graupner Rookie S simply an unbeatable carefree package also or especially for beginners super useful (for the Rookie). The MX-12 in conjunction with the receiver is certainly for Pro's also not a bad grip. Whether now Car, surface models (airplane) or Heli.
So in short, smaller, more robust, accurate, wide-ranging and reliable receiver !!!
A strong buy recommendation.
