I changed the battery from A 4.8 2700 amp Nim to A 4.8 1400 Ni-Cad just to see if that makes and dif. I also changed out every line in the fuel system then pulled the needels and turned over the engine flushing out the carb. Also opened up the diaphram plate and checked the pump. Added more foam around the ignition. Everything looks good to go so I will fire it up tomorrow and see what happens. Can't fly it yet but hope to get to the field this week and give it another try.
