Don't get your tats in a tingle over it.
Tanks don't get airborne when they go tail first like many "sports cars " do. And, by the time you are going fast enough to do it, if you do ,you'll have a plate full of other concerns. The major one will be traction and how to transfer the huge amount of power you are making to the salt.................
You will find that the majority of those who weigh into the argument about tanks as "wings" see them as a two dimensional object because they drive cars with doors on them. Build it big enough to fit all your crap in it, build it heavy and if your spider senses tell you that there's more weight at the back than the front then stick a tail on it. By the time you've made the effort to get that far someone with more smarts than you will stick their head up and say " can I help with that?" and they may be just what you need.
This is just based on my experience of building one and seeing others run through the relentless hail of advicefire....some make it, god bless 'em, but many don't.
If you are taking on partners in this make sure they are up for the long-haul.
PS. That was a beautiful tank Tony, the splitter work was gorgeous.....in that pic though something is missing....
