I have an RCS 140 that was running perfect and quit on landing and had no spark. 24 hours later when checking it it had a great blue/white spark thinking it would run i fueled it up and went to start it. After 20 flips of the prop it made no attempt to start i pulled the prop and once again no spark at all.

I am using an 1100 milliamp NiCad which has checked out fine although it is not a yellow or red cell pack, could this be the problem? And has anyone ever had this problem with an RCS 140?
