Default Re: DA 85 cost me a QQ Yak 54 101

Do you have a choke servo? do you have an optical ignition kill with the receiver failsafe set for either of these to kill your engine? have you thoroughly checked everything else pertaining to the powerplant before assuming that it was the engine's fault? I'm not saying that it definitely wasn't something pertaining to the actual engine or ignition, but I'd definitely rule out 100% everything else before making a post with a title that pretty much blatently says that you don't have a plane anymore and it's Desert Aircraft's fault. any number of things could have happened - a failsafe that cut your engine off (due to interference from the ignition - which you can still get even if you are on 2.4), a bad battery, battery connection in the pack or wire connector, internally broken wire in the battery or switch lead, a faulty ignition kill unit (if you have one), fauty switch, a bad choke servo (if you have one)that went to full choke after failing, bad throttle servo, fouled plug, dirty spark plug cap, too lean, too rich, bad fuel - the list goes on and on. Just showing that it could be a huge number of things besides the engine itself.
I can understand that you are rather upset. I lost a 75cc extra after only 10 flights because the engine quite in a bad spot (pushing into a hover from an inverted harrier that started at like 3 feet off the deck). I sent (well, drove) the engine to DA, and besides needing the hub mod (which had not affected the engine at the time of the crash) they found nothing.
Bottom line is that $h!t happens, and I just wrote the crash off to me having too much fun and getting too comfortable with a plane that had a new engine in it that wasn't even broken in and probably not properly tuned yet.
Even if DA does find something that would obviously have caused your engine to die, chances are that it will ultimately not point to a manufacturing defect (which usually show their ugly faces early in the engine's life), and in the unlikely event that it does, its still not going to get you your plane back.
Lick your wounds, send the engine in for a check-up, get it back and buy another plane.
