Well done. It looks great. Like the use of the landing gear strap. I try and use as much metal as possible for strength and durability. Using metal to fill would seem to give it more weight which is good. I used two part epoxy. Also you didn't reinforce the sides, but instead you used a C channel. How does that hold up? Is there any flexing. It is hard for me to break things down for show and tell like you do. Great job!!
So now how does the tank run with the new suspension?
