Semiauto mechbox Lock-up
 

Dear sir,
I recently built a customized mechbox for my M16A2. Apparently, the gun fire normly on full auto, but when I fire it on semiauto, it automatically jammed after one single shot. I tried to switch back to auto but there is no trigger response and the motor didn't even make a sound. I pull the motor out and tested it. The motor work just fine. I'm using Guarder IFTU gear for this mechbox. Kindly advice me as of how I can fix this problem

fully charge battery, try again.

Dear sir,
I'm using King Arms Lipo 1600 mAH battery and the battery are fully charged when I run it on the M16. Regardless, I would like to know a way in which I can permanently disable semi auto function on my AEG if I cant find a solution for semiauto lock-up.

what voltage? what spring? what other upgrades in this 'fully customized' mechbox?

Dear sir,
This is my spec for the new mechbox;
Deepfire reinforced V2 6mm gearbox
Guarder IFTU gears
Guarder Halftooth Piston
Guarder IFTU motor
SP 150 ( changed into PDI 210% with hope to find a solution for this problem, yet still not solvable)
King Arms 11.1 V 1600maH Lipo battery.
