RE: BME 110
uh. . hmmm. . I think the 110, even on standard mufflers, would be a WEEE bit much for that airframe without some serious beefing of the wing joints, cabanes, and interplane struts. Running a 3-blade would help a lot with that combination, because of the thrust loss, and I'd highly advise it if you go that direction.
DkJens. . be advised . . .the 110 on the 3.0M Composite-Arf will work, but MAN it gets noisey. I just took my 110 off my "heavy" (36 lbs DRY) 40% CA330, not because it would not pull it, but because I was on the gas enough that it was REALLY loud, and I have to fly IMAC with this plane (94 dB limit and NO ripping allowed) I recommend the MEjzlik 28-10 for best pulling power in that combination, and keep it as LIGHT as possible, single elevator servos, only 3 rudder servos, and 2 servos per wing. Anything over 34 lbs is gonna require lots of upper throttle range to fly well, though it will definitely do it.
On the other hand, my 29 lbs 40% is a DREAM to fly, no matter what prop I use, and the 29-10 Biela makes a great Pattern prop for this plane while the 28-10 Mejzlik or Menz work really well for 3D. Come to think of it, I've never used a 26 or 27" prop on any of my Xtreme's. Just seems right to start off with the 28" props.
