So, I must be pretty dumb....I read through all the instructions about mounting my engine, but naturally didn't look at the pictures. It turned out my needle valve poked into the fuselage, so I made a notch for it. However, I later realized [today about 10 minutes ago] that the reason it was too low was because I mounted the engine mounts upside down. Now, when I redid it the right way, the needle valve JUST clears the side, well the side that would've been there if I didn't put the notch in it. So, now I have a wasted notch, and I'm wondering if there's anything I should or need to do about it? Oh, and now my left thrust is right thrust, that's good right?
