7.7mm gun replacement

[Ajacobi]

Hi, I noticed that my right 7.7mm gun is not working, I already asked for a replacement but I want to know from those who have had to replace either one or both guns…what’s the best and easiest way to get to the board to unplug and replace the gun without have to break the small tube like parts that prevent you from removing the part in front of the screws?

I would recommend the following, remove the gun and LED.  Put the new LED in the tester you used to check the motor for the propeller to make sure it works.  Then, carefully snip the red and black wires that connect to the board, as well as the LED light.  Use a sharp knife to scrape away the wire coating and either solder or twist the wires together- red with red, black with black, and cut a small strip of electrician tape and wrap it tightly around where the wires are reconnected.  Gently tuck them in so they wont interfere or pinch when you close up the fuselage.  I had to do this with the three wire plug for the landing gear switch.  It works fine.

Your other choice is to remove the fuel tank and the bulkhead.  Refer to assembly instructions from this pack.

I was asking about how to remove the fuel tank and bulkhead without removing the spacer or brace or whatever we had to put on after the bulkhead with glue, is it possible or am I going to have to cut it off and glue it back on after the switch is done?

That is called the engine mount supports, and yes you will have to nip that off to get at the bulkhead and fuel tank for removal.  The good news, its not weigh bearing, its there for looks, the engine is self supporting. you will have to re-glue in place per the instructions when you are done.  Use a sharp pair of sprue cutters and cut as flush as you can to the support brace and the bulkhead.  Recommend CA glue to reattach.

it is unfortunate I'll have to cut it...but it's the only option i have due to not owning a soldering kit...plus the led needs to be completely replaced

You can get a soldering set at Hobby Lobby for a few $.  By following the above, you can change the LED with out removing anything.  What ever is easiest for you.

I can’t remember if I ever soldered electronics before so I’ll go with removing the tank
