Hahah! .. You're telling me.
I'm going to Operation: Coastal Uprising in Ohio on the 28th and if I don't have my 5 DeepFire Midcaps then I'm going there with only one 70 round midcap for the M14.. Which I guess would be good, if I wasn't going assault for it.
As far as your question goes.. It's your connection and motor that cause the response time, as soon as you pull the trigger the circut is sent to the battery pretty much telling it to "GIVE IT SOME JUICE!".. Once that's said the battery releases a small amount to the motor, which in turn.. Get's really happy and starts doing spins (Haha.. Seriously, it just activates and pulls the spring back) which then makes her fire. Unlike a SystemA or something else of high quality where you have literally a 0.1 second response time to a trigger pull.. You'll have to upgrade some pieces in your unit to get it working. We'll start with basic mechanics first.
Check all the wires leading from the motor to the gearbox, and from the battery to the gearbox, see if anything is torn, loosly placed, or dirty (You'll see a little black or something on the contacts). If it's torn or loose, pull out the soldiering iron and fix the old boy.. If you aren't good with that, take it to a hobby shop (Not the entire rifle.. Just the connection pieces) and ask for it to be done.. Shouldn't take them longer than 20 seconds and cost you anything more than $5.00.
If it's dirty, get a little rubbing alcohol and clean it up, then reassemble.. Note that you're working on an M14, and their Version 7 gearboxes are a little tricky, so be careful.. Again, if you don't feel comfortable.. Get someone that does (Not trying to plug anyone here.. But I usually have Tex do all my work, due to his amazing jobs).
Now.. If that is fixed and you're still having problems.. Check to see how much battery life you have (I suppose I should have listed this as the first.. Because it's the most easily messed up).. If you shoot and it comes out really weak and slow, chances are your battery is low (Hey, I can ryme!).
Finally, if all problems said above are fixed and corrected, or are 100% fine to begin with.. Then replace the motor, or check the contacts to make sure you're getting a 100% energy transference and spring pull out of it.
That's all I can think of that'll increase in that aspect.. The best thing you can do really is grab a camera and video tape you firing the weapon, so we can see exactly what sounds it makes and what it's doing.
