Can anyone tell me which of these would be a good choice for an 8.5 pound goldberg ultimate?

Hey I have a GB Ultimate and I have a Saito 120 with an APC 15X8 prop. The plane has unlimited vertical!

Ultimate has told you the truth,the 120 and the bonus that goes with it,the sound.

That sounds like the engine I will go with, I have been going crazy trying to pick the best engine, I didn't realize it would be this difficult! Anyway just wanted to say thank's for the help, this forum is awsome!!!!

if you haven't actually purchased the engine yet, and are set on a saito...go up to the 150 or even the 180......150 has the same case, so weight is almost the same ..180 weighs about an ounce more and case is same size but slightly different.... general rule is if you can get a bigger engine with the same weight....get the bigger motor .......you may not need the power....but then again .....you might !!

Just be aware the 150 and 180 are real frame shakers compared to the sewing machine smooth 120 . The bigger engines also like bigger props which may or may not be a clearance problem.
Allow for a bigger tank too

I have not purchased an engine yet, I was hoping for some more input, before my decision.
I'm learning more in just a couple of day's than I have in the last few month's and I appreciate all the help greatly! I'm not totally set on a saito just yet, I didn't think it was gonna be this hard!

( Lady Flyer, you seem to know alot about the y.s engines. would the 91 fz be a good choice for the gb ultimate at around 8 pounds?)
