HL Leo 2 Airsoft Problem
 

So I haven't turned on the airsoft function for a while, and I did so today since I felt like shooting stuff. When I flipped the airsoft switch on top of the turret, the tank keeps firing even without input! It only stops when I turn off the airsoft switch. Total shutdown didn't help. Even with the engine off, the gun keeps firing if the switch is flipped. Battery is fully charged. Any ideas?:confused:

A clark board will do that if the trigger switch isn't plugged in right. What electronics do you have? Is it just the sound that's continuous or do you get BB after BB?

Running stock right now. Both are continuous! No sound if the engine's dead, though.

I'd check all my wiring to make sure nothing's crossed or rubbed bare and if there's nothing wrong I would suspect the MFU. Is it the 2.4? Do you have any other tanks you can test with? Maybe put a different MFU in the Leo or move that MFU to a different tank and see if it still acts the same way.

I would check the limit switch on the airsoft gun. These are a flmsy affair. If the switch is staying in contact then there is nothing to turn the airsoft off. Open the tank. Look up in the turret to the airsoft gun. You should be able to see this switch. You will need to pry apart the contacts ever so slightly..

Everything else works, except the gun keeps cycling?

Cheers.

Hi, sorry for the lateness, been busy fixing up motors and fans hehe. Limit switch? Do I need to take apart the turret to get to that? Sorry, still kind of new to this. :D

You have to pull the upper hull off and then you can see the contacts Dan is referring to. They're at the back of the housing extending up into the square opening. Here's a pic of mine since I have it apart at the moment.

For a quick test just unplug the trigger switch. You won't get track recoil or cannon sound, but it tests the trigger switch (also known as the micro-switch).

Just checked it out. My limit switch seems to be fine, looks exactly like yours. For good measure I tested the tank with the 2-pin connector from that switch unplugged. Same results - turning on the airsoft function from the turret results in continuous firing, just withou sound and track recoil. :confused:

Definitely sounds like the MFU. Where are you? Maybe I can help.

Blast!!! I'm in Manila. :(

I'm not sure about postage from the US to Manila. If it's not too much I could maybe send an MFU to see if that fixes the problem.

Exactly what kind of tank is it, and is it your only tank?

Oh wow man you don't have to do that! Maybe I could fix it up on my own, if it's possible? It's a HL Leopard 2, the 2.4ghz version. My only tank for now, but hopefully it's the first of many! http://www.rcuniverse.com/forum/atta...mentid=2132057

Sooo given that the contacts are fine, is the MFU definitely the problem, and there's nothing I can do to fix it other than getting a new one? :confused:
