I am a complete noob to this sport. I recently got the H9 P-51 PTS and took it out to start the engine and taxi it around for a while. It went really well. I followed all the different posts check engine mount, servos, ... After the first start (the engine started remarkebly well by the way) I taxied round the local school parking lot for bout 40 mins. I had a blast and I can't wai for its first flight with the instructor. I live in Denver so the engine ran real rich but it pointed out an issue. The exhaust on this thing points right to the side of this beautiful aircraft and directly to the top of the wing. I did take the muffler apart to blue loc-tite the thing.

So after all this I was thinking...can I rotate the hole downward so it does not spray all over the aircraft?

Any help would be appreciated.
