Hello, I’m posting this today because I’ve been on this model for a long time and I can’t get it to fire properly or it doesn’t work. I’d like to know if anyone here has done this model before and could help me please. This is one of my favorite models and I can’t seem to get it to work. Thanks to anyone who can help me


Probably the SY22. I’ve never built one, but many have with success. The NULL is supposed to be an improvement over the NAG, but I have yet to try one of those either.
