Fixing those loose battery connections in your transmitter

It's obvious that not all batteries are created equal, but sometimes their dimensions, most importantly length can cause problems as the battery won't make proper contact because it's too short. I've noticed the problem more prevalent on rechargeable batteries.

Stretching the springs doesn't always work because the battery stop on the transmitter prevents the postive (+) terminal from reaching the flat plate. To fix this you need to pry the plate out a bit.

Here's a stock battery plate:

Simply insert a screwdriver or better yet I'm using some pointy scissors:

Do the twist:

And the final result:

If your quad is falling out of the sky do to momentary battery connection problems, this is the first thing you should check.

Great advice. Almost all the RTF TX's suffer from "inferior contact syndrome". Short of a rechargeable battery mod, this is the best bet. Also some thin cheap foam can be attached to the inside back battery cover to kill the slop of some causing the double A's from having intermittent contact.
