Best Sequence Airplane
FC 3M Extra 330: I have one of these (under the composite-arf banner). Excellent for sequence- you'd be hard pressed to find something better.
Carden 40% Extra: Have flown a couple of these- also excellent. A bit heavier thant he FC/CA 330.
Aeroworks Ultimate (too heavy for 150cc?)
Don't know- haven't flown one of these- I'd be tempted to put a ZDZ 210 in one.
FC Yak 55 (same question): Couple of them are local here and have ZDZ 210's in them. Have also seen one of them fly with a 3W 150. Impressive aircraft- Flies very well- though I have no first hand experience.
TBM 42% Extra 260: Again- have only seen them fly and they seem to fly great.
In short- you pick the one you like to look at the best- you won't be dissapointed with any of them.
