I've run RB's off-road mills since '97. So naturally I've been skeptical of the Killer 9, because of the origin of it's manufacturing. However, because of it's affordability, I purchased one a few weeks ago, and OOOHHHHH MANNNNNN! I have a new best friend.

Here's my report from last weekend's race.

Well my K9 survived it's first race, on a cool autumn humid day. I
arrived at the track with only 7-8 tanks through the motor, so I knew
I would still not likely have max power before the end of the day. My
plan was to putt around smoothly and stay out of everyones way at Valley Field's huge off-road layout.

Well that strategy actually worked beyond expectation. After a rain
delay, I tq'd both rounds 1 and 2. I led the A-main from start to
finish, and afterwards, everyone asked me how I maintained a race pace
while leaving a thick blue trail throughout the full length of the
straightaway for the entire race. Both the original RB5T plug and the
piston top look brand new still. And there's no play on the conrod.
I'm definitely ordering another for next season. I'm using an 053
pipe and carbon shoes with 1.0 springs. Thanks RB!!!!!!!!!!!!
