HI Guys,
I have just bought Ultimate 120. I would like to know, what engine is the best for that model ?
I mean OS Engine of course: 0.91 FX ( 2 s) ; 1.20 AX (2 s) or 1.20 FS (4 s.)
I think 1.20 FS will be OK. [8D]Am I right ?
Best regards
Peter
I fly the older ( Pink ) version which is heavier with an O.S. 1.20 Surpass III FS Pumped.
While the plane flies very well, it is NOT "unlimited verticals" so I wish it had a bit more power.
The yellow version of the 1.20 is much lighter and should do well with the 1.20 FS but a bit more engine power may be recommended.
The 1.20AX produces more power than the FS ( more akin to a 1.60-1.80 Four Stroker ) so it should be fine.... if you go this route you'll need a Pitts Style inverted mount muffler though.
The .91 FX would be similiar in performance to the 1.20 FS or there-abouts.
