hello all i'm a proud owner of 3 saito's and i love them all. great running engines. i am looking for some advise on my 150. it is mounted in a aeroworks yak 90 120 and it flys it great with a zoar 16/8 prop. if it is running level and i go straight up it will go almost out of sight. that thing really climbs. but in a hover well atleast the best i can do when i punch the gas it just bogs. no pull out power at all. i installed a new fuel tank and lines. made i a 3 line system so the feed to the carb is only about 5-6". i think the hs needle is around 2 1/2 out and not sure what low is but it has good smoke and transistions great. i was thinking of using a pump and seeing if that works better. by the way it is the stock exhaust. i would love some advise.
