SS Thank you for the tip on the smoke tubes, I will consider that, I had a Pitts style muffler before and that is what happened to it when the gear collapsed lucklly I was working at a machine shop and we had wellding for that kind of metal.

So far I haven't had time to complete my R70 [:@] [:'(][:'(], I just need to do the final details and radio setup, anyways our runway is under reconstruction so, no flying for the next 2 weeks or so.
