Just an update & clarification...
I sold my Enforcer without the Tower .75. I bench tested the engine and found out that a 11x7P APC is not the same as a regular 11x7 APC. My Tower .75 repeated the same RPM with a 12x6 puller (12,600) but turned 13500 rpm with a regular 11x7. With the pusher version it turned 14,900. Most-likely, the pitch is different but possibly the "shadow" of the engine and plane cause this difference.
Anyone else notice a large difference in the pusher vs. the regular puller configuration ??

I ditto the 12,500 with a 12x6 APC! I used 15% Cool Power though.
But I got an unbelievable 14,900 to 15,000 with a 11x7P APC. Checked this twice. I had to richen the low end quite a bit but the engine performs very well. It's a little more touchy than an OS but what a powerhouse and at a very fair price.
