My Sig Cap flies VERY well. One thing I've learned though is don't skimp on the servos. I've had three servo failures on three seperate occasions. Each time I replaced the offending surface(s) with metal gear digitals and the problem went away As far as 3d I'm no champ but with my Saito 1.80 I was able to CLIMB while in an inverted flat-spin and I have been able to harrier it but I'm new so take that for what it's worth.
