RE: WSN T34 and M1A2 Abrams with Elmod
Thank You John for the help and instructions in "HE Leo2 Upgrade"
I modified M1A2 Abrams in the similair way using HL gearboxes and motors + HL Pershing plastic tracks and driving wheels (metal is too expensive)
I also made some little changes in the front wheel.
Now the tank moves more smoothly.
I think that the Hobby Engine M1A2 is good as the base model for the further upgrades. Its painting and detaling are quite good.
I have a little problem - how to connect the recoil switch in Hobby Engine M1A2 to the Elmod electronics
I tried to use Pin 8 of the P2 connector in TLS module ( as it was in WSN T34 conversion) . In WSN T34 conversion the pin 8 of connector 2 is for the switch which is closed when the barrel reaches the inner most position. This information is necessary to switch the motor off in the right time so the barrel returns in the correct position. This function is only when the Booster is jumpered to T34 mode
I connected one end of the switch to the pin 8 and the second (via 300 ohm resistor) to:
1. ground 0V
2. power supply +7.2V
but there was no effect , the gun/recoil motor was still supplied (when the switch was closed) and during the
gun fire the barrel recoils twice /should once/
Is there any pull up resistors needed for pin 8 , maybe it is sensitive not on level of the voltage but on the edge (falling/rising) ?
How to solve this problem.
