I finally got to test out my CL converted TT42 and TT46.  I have a number of each of them and have been using them on RC for a number of years.  The TT42 break was fantastic, almost to much.  When it kicked into 2 cycle the speed increased dramatically much more than I've ever experienced before.  I'm hoping there may be a way to reduce it somewhat.  All in all, I'm very happy with its performance.  I had it on a Brodak P40, 60 foot lines with an 11x5 APC prop, stock muffler and no muffler pressure.

The TT46 was just the reverse.  I put it on a Brodak Cardinal with 65 foot lines, a B&O 12x3 and a Tower Hobby muffler. It seemed to run more consistant with muffler pressure.  I had to add 3 1/2 Oz. of weight  to the tail.  After a few flights I finally got it running about the right speed.  It seemed fine in level flight but slowed down each time I started a manuver.  It still performed pretty well.

Any suggestions will be greatly appreciated.
