Hope I get mine up and flying soon. I have a few ideas for mods and whatnot. Theres many great things to do already in the thread.

I don't use the rudder much but I can wag its tail like a dog waiting for a Milkbone.

Took off early today, to test out thermal ability.... a bit disappointed, definitely no soarer. Everytime I thought, ah there's a bubble of hot air and tried to turn, I fell out in a spin...

Zephyr performs better at the slope or in slermals. She's too fast for normal thermalling. Maybe it works if you get her over 600 feet, where thermals tend to get bigger, but at that height, she's becoming frightfully small...

A little disappointed today.....I was flying and noticed that the plane kept rolling to the left. After checking the plane, the screw mounts came loose. In addition, I lost the plastic piece that the wing pegs go into. Good job hk.

Lesson learned.. it's not hks fault.. you have to check EVERYTHING that's "done for you" by manufacturers.. it's not a lamborghini or a ferrari.. it's mass production

No lesson learned. I checked everything out of the box. Those screw mounts are in the inside of the foam. One wouldn't expect to have to glue those back in place. The plastic piece is understandable, but these are embedded in the foam.

Yes, hobbyking did advertise this as their Lamborghini or ferarri.
That's also a poor example, comparing cars to hobby planes. You wouldn't expect to have to go back and tighten all of your belts after buying a brand new Volkswagen?

My little piece that the LE of the wings hook into the fuselage came off and lost it the second flight. I had to fabricate one out of birchwood.

As has been documented throughout this thread alot of items on the zephyr either require glueing or have insufficient glue.

I found that the aileron servo covers, aileron servos are not glued from factory
The plastic part at the front where the wing attaches needs extra glue. Also reinforcing in the area the wing pins attach to the wing is required (i filled with hot glue)
Where the wings bolts connect is not glued in (purely captured in the foam. Rips out after one non perfect landing)

Surely this one is absolutely critical.

Mine fell off just trial fitting the wing. As supplied there was a minimal glue surface between glossy foam and some smooth raised ribs. It is loaded in tension (weakest) not shear. If this comes off in flight under even slight -ve G the wing will detach at the FRONT. Can imagine some pretty exciting separation events at high speed.

I am impressed by the innovation of the Zephyr in general but this is a real design weakness IMO.

Sadly I glued mine and waited a day, and it still fell off. I'm made a replacement from foam and fiberglass. I'm still gonna run screws though the wing. That's the weakest point imo.

The wing area setup really opens up the possibility to use another wing set wisignificant airframe mods. That may ultimately be the easiest way to fix the 4s flutter

Has anyone tried running a strip of silk, Sky-Loft, or very thin glass fiber alone the thickest part of the wing? Leading edge? Trailing edge? All of the above? Or, What about covering the whole thing with a low temp covering material? Laminating just about anything should help to damp flutter.

Yup, laminating film was mentioned. a few pages back I ordered myself a roll of 5 mil CP laminating film.
