Zeeb,
Thanks for the suggestions, I DID move the ignition inside and that's when I quite having dead sticks for quite a while. Just all of a sudden without doing any changes, the problem started again. I change the entire fuel system, tank, clunk, lines, filter, everything and still does it. My next thing is either try a new ignition box or rebuilding the carb, but I doubt it's the carb as it runs fine for anywhere from 4 - 7 minutes then just suddenly dies. Usually when the engine overheats, you can hear it sag a little, lose power, then it dies. Mine, just gives a cough, then about 5-10 seconds later dies, almost like it's running out of fuel.
On another note, I got a good look at the B model at the AMA show and talked to Rocco quite a bit. It's really a nice looking model and I'm sure the fans of B models will like it. (Me - I'm a D model type!)
Sounds like it's pointing more toward the module but there are a couple of other things to try. I've got a little 50cc aerobat that was doing something similar. The local engine guru suggested I try changing the battery which I did and it didn't help. So he suggested plugging the battery directly into the ignition to by pass the switch. I pooh poohed that idea thinking a switch would either work or not and I chased a bunch of other stuff including the fuel system and carb overhaul. It was still doing it so in desperation I connected the battery directly to the module and presto! problem solved, it was the switch going bad.
Other "shot in the dark" possibilities before you go buying and ignition module; DA's are notorious for this type of behavior if the Power Pole connectors feeding the module have not been replaced. Weight and vibration I guess causes them to develop an intermittant short near the connectors. Other issue although not as common is the same thing in the ignition timing pickup wire at the two little servo connectors, wires start going south and it's hidden by the nifty red jacket on that wire.
I don't suppose it'll do it on the ground? I was thinking maybe you could try warming up the module with a heat gun and see if it does it? Bit extreme on that one and I've never done it but the idea popped into my head. Last, what has DA got to say about it?
On the new B model, I'm not a fan but IIRC you can buy it without landing gear? Wonder why????
