For the price the flash is hard to beat, however the quality of the RB and the ease of tuning justifies the price difference if you ask me. After 17 liter's my RB R3 RC is still fast, not fast enough for high end competition though, but it still idles perfectly, makes a good practice and rain-engine. For me this was the first engine which lasted more as 10 liter's in high competition use.

However if you want the fastest I recommend you to take a look at the Capricorn LAB E01 WC, mine makes flash engines (or any other engine) run home crying.
