Hi Bill,

I like the 17x12 APC.  With 15% Magnum and the pipe set to ~24" (plug 
to baffle) you can expect initial rpm's in the 8000 - 8200 range.  On 
mine, I saw an additional increase of ~200 rpm over the first 30 
flights or so.  I use ES Composites pipes; I don't have any 
experience with the Bolly pipes.

With Magnum #1, I was initially getting 8200-8400 rpm.  It steadily 
increased to ~8600 peak rpm at the 30 flight point (I flew it at 8400 
rpm).  The flight performance was spectacular to say the least.
