Anybody have the same problem ,that I do? it seams that the connection from the ESC to timer come lose sometimes. eather in mid flight or on start up, this is not often but still happens, in flight level is ok but in a stunt it cuts out and returns normal. would tying the connector help?

I am wondering if you are getting some type of low voltage or overcurrent cutoff. I can't believe that you are actually losing the physical connection--unless you have a broken wire or perhaps a faulty timer.

How are your batteries doing. Is the cutoff a random thing (over the flight) or happening at specific times??--like in a maneuver where the current draw is likely to be higher than average.

I guess you need to replace the connector on the ESC. I think you can buy a pigtail (so you can either cut the existing wires and solder the pigtail onto them, or take off the original connector and wire and solder on the new pigtail with connector.

Here would be a test I would do first. Take off the prop. Start the system up, and as it is running, wiggle the wire and/or the connector near where it makes contact to the timer. If the motor stops, then it is the connection.

Another possibility is the the wire prongs on the timer don't make a good contact to the timer circuit board solder pads. I had a JMP-2 which arrived DOA from the store. I was just about ready to send it back when I looked more carefully at the circuit board and saw that a couple of pins were missing solder, or didn't have a nice clean solder connection on the circuit board pad. A small touch of the soldering iron and a little solder fixed that up, and that's the timer I am still using today.

Hi Larry,
I have seen dental floss tied around the two connectors threaded between the wires, heat-shrink tubing, tape, more tape, and even schnazzy injection-molded connector keepers like these!  http://sonictronics.com/xcart/home.php?cat=395

It doesn't have to happen a lot, Larry!

I fly a lot of RC and make up all my own connectors and servo leads. You will sometimes get one that just doesn't mate right. Maybe just over polished. They should fit snug. Just replace it if you want or you can do what we do in rc, use a little electrical tape to wrap the connection. It bonds very well to the plastic and will hold them together thru any of the gentle maneuvers we do in CL aerobatics... it holds in all the violent moves we do in 3D rc with no problems and with very long wires attached getting all thrown about.
