I just ordered my Katana from Creek Hobbies,I want to know your opinions on engines,preferablly from people who have actually owned these engines,I want good 3D and good pull out power.I really would like gas,but could deal with glow if it is the better choice.I spoke with Creek and they said with the OS 1.60,I would need about 5oz lead up front,I really don't like to add dead weight to a plane.Here's what I have narrowed it down to,although it is not too narrow:

OS 1.60 w/Jett turboJett Muffler
MVVS 1.60 Gasser
RCS 1.40 Gasser
RCS 1.80 Gasser
Thanks,
Mike
