RB WS7III : superb engine! stable and linear power band. longevity second to non... very easy to tune... not as powerful as the C6BBT. heat treated crankcast, biturbo crankshalf... many many worlds...

RB C6BBT : very very powerful... lots of torque and top end. one of the fastest engines... turbo plug sometimes can be sticky... very petty on tuning. must know how to tune it to get it to run properly... if not, it's flame out derby... best thing is the fuel consumption... we can get 11 mins from a tank with 120ish degree c... not sure how much is that in F...

OS Speed VZB alu : my favourite engine. very stable for a turbo plug engine... idles like a standard plug engine.. the balance crank is amazing... the fuel doesn't 'jumps' even when filled to the brim... engine feels light to rev... linear power with tremendous top end... parts a lot cheaper than RB.. not to mention the DLC coated crank. low friction, prevent the crank from rusting, and almost no wear where the clutch bell bearing sits... superb idea....

OS VZB : a lot cheaper than the speed, just that no balance crank... but still a great engine... if on a budget, i'll go for this engine rather than the taiwanese stuff...please check if it's the updated version before shelling out $$... the older ones are with 10 balls on the rear bearing... the newer ones are with 9 balls... the older ones suffer big time on rear bearing problems... the new ones got rid of this problem...


2 cents...
