Sorry about your loss but no electronics are 100% failsafe. Qantas recently had a very nasty incident (serious injuries were incurred) when a flight control computer component malfunctioned on an A330, control being lost for a short time, and Singapore Airlines had a similar incident on a 777 fitted with the sametype of unit.</p>

I have had 100 % success to date (20 months with not a single frame loss) with Spektrum in 3 jets but have just been testing the new Weatronics Micro 12 channel 2.4 This is a bi-directional unit which gives a constant confirmation of the link by a green led on the Tx unit , records details of the link on an SD card for later perusal on your computer and can trigger warnings, red led or an aural warning if using the earpiece, of RSSI, battery voltage and receiver temperature. In addition, due to the patch antenna it has exceptional range.</p>

First impressions of this unit (11 jet flights with perfect operation) are highly favourable and continuous confirmation of a perfect RF link thanks to the bidirectional operation is really excellent. All these Micro receivers, 8 , 10 or 12 channels, have inputs for two batteries virtualy eliminating the chance of power failure, too.</p>

The larger weatronics DR will have all of the facilities of their previous unit plus some and uses the same 2.4 Rf of the Micro system. I hope to have one of these for evaluation very soon.</p>

That said 35/ 36/72 mhz is far from dead, I still fly my Hawks on that band and Nick Smith was flying his superb KingCat at Wroughton yesterday on 35 with continued complete success.</p>
