Did your servos fail? Or did you replace them before trying them?

Any more actual failures anyone?

On my 3rd or 4th flight I landed kind of hard on the nose which might have weakened the spar. By no means was it a hard enough hit to warrant any concern for a broken spar. I re-launched and noticed that the wings were rather 'floppy.' Upon inspection I found the spar had broke where the wings joined. It was easily fixed with a carbon arrow shaft and some added carbon reinforcing throughout the wings. No problems since.

Wingspar broke during flight, 2 servos have stripped gears within 6 or 7 flights. You may be correct about stiff control surfaces being part of that problem. Two horns broke and the plastic peace that snaps onto the horn broke on one wing the first time I tried to adjust the throw.

I've heard of Someone else getting one that didn't have washers. You could try running a magnet over the front to see if maybe it would locate them.

Long answer - It helps you get the airframe setup correctly. Once you are about 4-5 mistakes high (around 200 ft.), shut off the motor, set the plane in about a 30-40 degree dive. Then, release all sticks and see how (if the plane recovers). Once it dives (and subsequently) glides correctly, we can start on the power setup. If we start moving the motor around, we can never be sure if the airplane is flying properly.

When I let off the throttle my right wing is still tipping down.

Hope this was helpful.

Have you done a static lateral balance yet? If it is in balance on the bench, then it almost has to be a warped wing (usually). In rare cases, a problem with the vertical stab or horizontal stab can cause that. (but, again, rare).
This is during the Dive/Glide test?

Sometimes, (i.e. on V3 RTF), there is a sizable ball bearing in a small pocket in the front of the fuselage. Hold the front of the fuselage up to a bright light and see if you spot the shadow of it.

By my opinion it is better to create it yourself even without removing a battery. Just use this connector and connect it with servo cable. Then connect it directly without need of removing battery.

I got the adapter cable on ebay by searching "808 #16 receiver" -- got mine from this person: http://www.ebay.com/itm/150815324522...#ht_1034wt_148

Have you freed up the hinges since then? Has that made a difference to performance or is that still a problem? Maybe dipping wing because servos aren't centering if the hinges haven't been freed?

My aileron throws are as they came (outer holes) and don't seem to need changing. I suppose I should to see just what difference it would make but rolls are as fast as I expect from the design.

The weights - mine had 4 large washers, ~68 grm from memory. Hotglued in, hot water for removal.

Both of those options look interesting.

Are there any issues with either over charging the camera battery or draining the Lipo. I would hate to lose control of my plane due to the camera.

My tailfeathers have been an issue from day one . The notch on the rear of the fuse was miscut when I received it. I thought I had that adjusted but after measuring, it looks like the rightside of the horizontal fin is slightly higher in relation to the vertical fin than the left side.

Yea the hinges have been freed up.

Thats what I was looking for! I found it. I wound up cutting off a tip of the nose to get at it. I didn't want to have to do that, but C'est la vie. It was rather tough to find. I took a T-Pin and inserted it several times, then took a knife and just cut off the end of the nose to find it. what a nuissance.
