Hi Guys,
I know some of you have opened up the Matty PKE and have poked around so I thought I’d ask this and get your advice.
While at Wondercon, a person on our team, took my my PKE without asking and proceeded to drop it. Now when it’s on the wings don’t fully extend and it makes a grinding noise.
Anyone have any idea what could be going on and if so do you thinmk is it repairable? I’m nervous to open it up, but I know I have no choice but to find out what’s going on.
Thanks for any advice you may have and I’ll post pictures later on when I open it up.
I really want bitchslap the person who did this,but the more important thing is to try and repair the unit.
It sounds like there might be slipped or broken gear teeth. The only way to know is to open it up.
Thanks I need to find the teardown thread so I know what I’m doing
I just reassembled mine today after deciding to remove the outer two shell pieces to repaint them.

I recommend extending the wings as far as they’ll go before you power it down and remove the batteries. I began disassembling mine with the wings retracted, and it made it tricky to get everything out.
This will make no sense until after you’ve got it in pieces, but the movement is accomplished by a motor that turns in a circle, which causes a T-shaped piece to move up and down. The t-bar is what pivots the wings simultaneously.
I never took a pic from the proper angle, but jackdoud’s teardown has a great pic of the T-bar:
At one point during reassembly, the T-bar and its connected moving pieces got jammed together and I had to unscrew the motor housing one more time to get everything clear. Maybe yours suffered a similar jam when it was dropped.

Alex that’s exactly what happened! I took it apart tonight, and the T bar was misaligned after some tinkering I was able to realign it and it works. I also took a q-tip with some RC grease and lubed it back up, works great now.
Thanks to all everyone’s help, I really appreciate it 
Great news! Now you don’t have to “b*tchslap” the person who dropped it.

The three bottom lights on the right wing are out on My matty pke. I haven’t use it in awhile and when I took out it out the box, then switch it on. I notice the lights were out. Has anyone else has this problem and if so, how do I fix this?
It’s unlikely anything inside the wing broke. Maybe the ribbon cable that connects it to the rest of the electronics came loose?
