Just maidened mine last weekend. It only needed a little up trim which wen away when I put the cowl back in (first flight was with no cowling). There is a very clear flight speed difference between the uncowled plane and the cowled one. I tracks very nicely except for the slight pull to the canopy in downlines. It weighs 7.8lbs with the OS 91 FX, Hitec Digitals, and a 4 cell 2000mah NiMh pack (my ony available).

The plane builds fast and is very accurate. The only dark points are the instructions (worthless), the diedral brace fitting (much more than the 4mm diedral recommended in the same manual), and the cockpit balsa (so hard it wouldn´t bend to conform to the turtledeck). There were no accesories whatsoever in my kit (not a single screw, horn, clevis, etc.) but I would have substituted them anyway.

The elevator pull-pull setup is a slight pain in the neck. I guess the next time I would go with the MK system. I alse needed to add a couple of 1/8 shims under the elevator servo to clear the lines with the rudder servo located to the back.

Other than that, it is the best 60-90 size flyer period. I gave my Swallow 90 away after flying this baby. The Epsilon is much more agile and nimble than my friend´s Widebody 60. The Epsilon will go from pure F3A style flight to 3D with no sweat. I will take some pictures next weekend weather permitting.
