GreenAcre:

Anton recommends no more than a 30lb turbine. My Dragon came in at under 30lbs . . .27lb to be exact. I am flying it with our Jet Central Super Eagle which is more than enough! It accelerates going vertical in the roll mode. Flying at full throttle, this jet picks up speed very, very fast due to the clean airframe.
I made no changes to the airframe other than a hard wood dowel inside the wing tube (personal assurance) for additional strength.
