RE: tuned pipes
The two meccoa (I used lower case on purpose) engines I have aren't worth the hay it cost to put in the horse that dropped them[:'(]. FYI. No transition, I couldn't keep them running in the air at all. Ran fine on the gound till about 4 seconds after they broke free of the ground. I finally took them off and replaced them with other engines. One time I actually called the LHS to ask if they would stay open for me to pick up another brand so I could fly the next day. I really wish I had the K&B I traded for them.[&o]
