<DIV>By the rule book the DX8 would be clearly illegal for pattern because of the telemetry. I doubt anyone would declare it so however.</DIV>

<DD>I just had one and sold it. Reasons:<BR><BR>
<DD>No stick switches<BR>
<DD>No split expo on each side of neutral. I use split expo, especially on elevator.<BR>
<DD>Mine came with the infamous stick deadband on three axes and I ended up sending it back twice to get it properly repaired.<BR>
<DD>Lockouts/glitching. Found a burned/corroded antenna connection in the receiver and sent it back for repair. Another Aurora 9 flyer also had glitching/lockouts at our field.<BR>
<DD>Only had digital throttle trim, and it cannot be mixed or assigned to a slider such that it only acts on low throttle.<BR><BR>
<DD>They promise lots of feature updates via firmware, but are VERY slow in releasing anything. And they won't say exactly what will be in the next release. Bugs in heli and sailplane setups. Requires purchase of a separate box to update firmware. Website in Korea that has the updates has had frequent outages. You CANNOT download the firmware and install it later. You MUST be hooked to the internet and download it real time. My perception is that they are more enthralled with telemetry (that was a year late in being released) than in getting the basic system up to snuff. Oh, and as far as I know, they still haven't released the 72mHz module promised last fall, if that is of any concern.<BR><BR>
<DD>Was glad to get rid of mine.<BR><BR>
