Hmm I like macieka's way of testing it out, but as Thunder mentioned, maybe they aren't in final alignment? Atleast it would get you close to the final alignment and from there you can adjust. As for motors, I'm starting to get confused haha! I think I'll take my chances for the sake of simplicity and grab a G&P. I'm not going to be using my aeg until spring/summer anyways so it can be changed later down the road.
As for the advice, I'll surely make sure to read up on the subject before attempting anything again with my aeg. I ordered a book the M4 book from airsoft press, don't know if it's any good, hopefully it will help.
Also, any recommendations for oil/lube? Don't know which to use for what. Thanks!
