Ok, so here's how it started...

The JST connector got stretched and finally the neg lead broke off, so I took the old connector off, and not having a replacement, direct wired the leads to the battery pack. not a problem, except for a split second, I had them reversed, and smoked the MOSFET controller. Not a problem... I went to www.digikey.com bought 3 mosfet controllers and replaced it, the other 2 chips I got to repair another fried 4N1 on another BCX, and the other chip as a spare. So, I replaced the MOSFET on the one BCX, and everything works fine.

Now, the one BCX 4N1 that I reversed the leads on...

I replaced the MOSFET that got smoked, and the motors work fine. While I was in there, I put a brand new longer plug for the battery in, soldered tot he board. Took teh old one out, soldered in a new one from hobbico. Motors work fine, but when I plug in the servos the green LED dims, and if I move the cyclic controls, the LED dims more, nothing happens with the servos, and it slows the motors down.

Why? What else coudl I have fried in there, that would cause this.

I want to add, that when in there, I noted that some of the components differed from the first 4N1 that I worked on. some of the components are in different locations, and the antenna is routed differently through the board.

I didn't see any other components that were visably toasty or discolored.
Anyone hazzard a guess as to the problem?

Thanks,
John
