Default Aviation design servo plates problem

Almost lost my jet because of those plates, my alieron servo plate caved in the wing and blocked the alieron, luckily the jet is ok .

This is the heads-up video for someone who installed those stock plates, that mostly installed in super scorpion and the larger aviation design models, they have multiple variations of plates that available to purchase from carbonfiber to aluminum, just check what condition are your plates before something happens

This has been a known problem for years already. So either make your own like Dansy above or 2 options below....

I don't have a dog in this fight as I do not own one of these jets but if those servo plates are a known issue and that brittle, why is AD still supplying them with kits? Seems like a needless risk.
thanks,

Thatís right why they even includ those junk plastic plates with their already so expensive models? They should not even use them, thatís a serious problem, Iím so lucky that I was able to safely landed the jet and not hurt no one with , USA lawyers just love that

Since these servos were glued in I'm wondering if the glue used played a part in making them brittle; kinda like thread locker will do to plastic?

These appear to be servo plates/covers on the vertical stab. Are the ones in the wing in the same condition?

Never mind! I just checked my Aviation Design Scorpion which is just about the same age as yours and it has the same problem! Does Aviation Design offer replacement ones?

Iím not sure if the glue goes to reaction with the plastic plates, I have those with 3m two face tape and some with just a drop off goop and they both have the same exact problem so Iím not sure about the glue reaction

It isn't the glue. My Scorpion has the same issue and my servos are not glued. You mention Aviation Design has aluminum replacements. Are they 100% aluminum or is there still plastic involved. The website doesn't say and it isn't obvious from the pictures.

The ones included with my new scorpion kit crumbled in my hands while i was handling then during building. I just replaced them with G10 pieces.


the larger concern was the 4 dots of CA that was used to ďglueĒ the horizontal stab pivot rod into the stab structure. After one flight one stab had enough slop in it to move 2Ē at the trailing edge.

I contacted Aviation Design and their servo covers are in fact 100% aluminum. I ordered a set for the wing. They do not have aluminum ones for the servo hatches on the vertical stabs of the Scorpion. Ultimate jets does not appear to have their carbon fiber ones in the size needed for the Scorpion vertical stabs. I have contacted them to see if that is true.

Almost lost my Super Scorpion because of the JUNK plates they supply. I purchased the Carbon Fiber ones from Ultimate Jets. Prepare to pay about 200 Bucks for them.

So my main question is why they still supply them with their already so expensive models? Maybe they should give you 3 sets and worming to replace them every 3 years?
