Status: offline 		Hi guys, i have a 30% 260 with a DA-50, first flew the plane last weekend and think its fantastic, i have one issue with it and wondered if anyone else is having the same problem,it seems that my DA is not happy in the cowl, the carburation seems to change very slightly at the bottom end? like the cowl is pressurising??

Any help would be great

Cheers
Simon

Status: offline 		Its all sorted thanks chaps it turned out to be the fault of the canister holder in the pipe tunnel.....it was blocking the whole tunnel and trapping all the hot air.....the carb on the da sits directly above the tunnel entrance,and was sucking hot air ....i noticed a vast difference in needle settings when the aircraft was inverted,when the aircraft was upside down the hot air was escaping,and the engine was drawing on cold air ,thus changing the mixture...problem solved

Cheers
Simon
