Hi,
Yesturday when I was landing my extra, and strong undercarrage
just collapsed! It wasn't even a hard landing,
when I got home, I realised all the insides was fuel soaked,
all the ply + balsa was fuel soaked.

But I cannot understand where the fuel is coming from,
so I have attached some pictures, and comments would be
appreciated

As you can see, the whole
powermodule is fuel soaked
