No,
There's a lot more to it than that. Way too many variables to broad-brush it. There's type and quality of the resin in the honeycomb, the way they're using it, etc. When properly utilized, honeycomb material is great. The problem here is how/where it's being used--not the fact that it's present.

Wow!!
Two very informative videos. It's nice to see the quality (actually the lack of quality) of that FEJ F-18 stab construction with the bit of a cutting blade glued to the skin! And those two "well placed" bits of the lowest grade of balsa wood haphazardly placed on the skin too. What's that all about? Vibration-dampening? I doub't it. Where is the Quality Control? Seems that no one is checking on the children who build these jets.
Proof that careless and inept workers are assembling these jets that people are paying thousands of dollars for. (not to also mention poor design)
Video# 2:
Rudder broken on first flight, and the stab is able to be moved up and down!! Yikes !!! Where's the quality in that? That guy was lucky to get his jet back, and good thing he kept the speed low.
Maybe the stab struck a dragon fly during flight which caused the break? Hahahahahaha!
How could anyone defend that company, or buy anything from them now?

Also, check out this video ...
At 0:35 you can see the stabs fluttering while the jet was on the ground and just after start-up!
Then you can see the left stab flutter agian at 0:55 as the jet is taxing out to the runway!!!

That is caused by the servos fighting the weight of the stab to maintain their center position.

Hi,
I'm not sure what's up with the stabs in the above video, but I've never had that happen to that extent and I've never static-balanced a stab. Of course, I've never owned a jet with a full-flying stab that was built/designed by someone who had no earthly idea what he was doing.
For the videos I posted, I'm sure it was just a case of bad servo choice...

Cause you know, if they say it, it must be true. Just like "they" can't put anything on the internet that isn't true.

I used what I learned with this jet on my second FEJ F-18F and flew it for four years with excellent results! https://www.youtube.com/watch?v=ZeCq...Dvi-Ew&index=4
I've said it before, I'll say it again, the original FEJ 1/7 F-18F is the best flying Super Hornet I've ever owned. I put close to 100 flights on that airframe, powered by a P-200 and you can see from the flight, I didn't baby it! Never a problem. I still own the Diamondback, and had planned to have it flying again until FEJ changed to HC construction and I didn't want to go thru the hassle of ordering the parts I needed to upgrade it.
Once FEJ changed this jet to HC construction, it became a completely different airframe. Quite frankly, IMO they ruined it. EDFJim, I think, will attest to that fact. As well as the others who's HC F-18F jets later crashed.
It's a shame that these threads can venture so far afield from the original thread such that it dilutes and completely obfuscates the original intent.
