Tailwheel:

I've got the Saito 150 with smoke. I'm using the TME system with NO special muffler. I got some really good info from this forum regarding smoke, if I can find the link I'll send it to you.

Basically what was recommended to me was to drill and tap a hole in the header for the oil fitting. No preheater, no special muffler. I saw videos of this fellas Christen Eagle with this set up and the smoke looked great.

I haven't been able to fly mine yet as the weather here in Michigan is nowhere near nice enough yet. I definitely want a nice day for the Stearman maiden.
