top speed: 68.5-69.9 mph depending on conditions and load
rpm: 5700-5850 depending on conditions/load/trim
really loose/unstable at WOT/trimmed out, very hard to reach the rev limiters

new 26p Bravo One FS

felt more stable at WOT/trimmed out, hit the rev limiters after trimming all the way out

I am definitely happy with how she runs, feels a little more stable at speed than she did with the mirage plus'... Went out today to get some numbers, amount of trim has a huge effect on mpg, trim was at 17% until 5500 rpm, then trimmed out to 30%

RPM--MPH--MPG
3000--32.4--2.73
3500--43.0--2.36
4000--49.7--1.80
4500--55.8--1.56
5000--62.0--1.35
5500--68.8--1.42**
5900--72.5--?.??**
**trimmed out

Added a bob's double jac for a little more height and adjustability, and a set of 28p Bravo 1 FS, new top speed 73.8 mph turning 5750. hoping to reach 75 mph with a little more dialing in...
