CTW Issues

So I just received a CTW from another member who, before shipping, said it worked flawlessly. Unfortunately, it is having a few issues right now since I got it. When I load a magazine, place it in the gun, and slap the bolt catch, I am only able to get about 10 rounds or so out before the blue light starts flashing. I know usually flashing blue light means dead battery, but I used two, well charged 11.1v lipos, and it did this on both batteries. After the gun starts flashing, I have to take out the mag, put it back in, switch from semi to safe back to semi before I can shoot again and the light goes from flashing to solid. Not only that, but after going to the second battery, a 11.1v 1200 mah 20c lipo that was 3/4 full, I held down the bolt catch and the battery drained in less than 10 seconds... Let me know whats up if you know. Thanks for the help.

I belive the problem is your ECU or you have somewhere a short circuit ... becouse when is a short circuit the battery is drain out ... of cource the short circuit can be in ECU becouse if was any problem whit the wires you should see any sparks or smoke ... or black areas on the body where the short circuit was

Like Venom said.. probably the ECU, do you have the old ECU or the newest one?

The seller said that a 2010 ECU had been installed.

Multiple shots in semi may be caused by an obstruction on the optical sensor, remove the board and swab the sensors with a rubbing alcohol soaked cue tip or something similar. To do so push the bolt catch pin and remove the bolt catch , then pull out the black plastic wire shield , then the board will simply pull right out ... Try this and let me know if it works.

Check the sector gear holes too. That's prown to dirt etc. Also as stated prob the ecu or in some cases the motors fried and is still sucking power to turn. Like an iniatial heavy charge will turn it then it won't turn ya get me. If ya got the money to do so I'd say just buy a new ecu and get the jg motor and it should be good. Also its possible but doubtful as the fuse would pop but could be the mosfet

Sector gear holes are an excellent tip.. my gears wouldnt align correctly if i opened the receiver until i cleaned the holes, you couldn`t see trough them.. used electronic spray. now its all clean and aligning as its suppose to. But also check what i wrote..

When you pull the trigger with the recievers split open to set the gear in the correct position, make sure you do not do not do it in direct sunlight. I had my PTW open at a field and the gears would never stop where they are supposed to. The sun was messing with the sensors. I moved to the shade and the gears were stopping properly.
