Well everyone today my dle-20 blew up.
Crank shaft pin broke but there was no other real damage besides the bearing from rubbing on the broke crank.
There are no signs of to much heat or not enough oil anywhere everything looks fine.
I use bel-ray oil at 40-1 ratio and have about 4 gallons through the motor now.
The plane was on a pretty gentle upline at full throttle when it let go.
Let me know what you guys think here is a few pictures.
