GB is on the money.I usually put a rape and pillage carbon steel bit into the dremel and hack out the braces in the middle so you can get your fingers in there and hold the engine mount nuts while you try to line them up and get them threaded.Plus it gives you room to fit whatever tank you like there,no fiddling with fuel lines either.After that i run a light bit glass round the forward bulkheads where i removed the cross bracing on the front formers,sweet as
That's the first time I have seen it called that.
It fits but that's a first. Once the area is opened there are a lot of things you can do in there like angle stock behind the fire wall. I just use foam to get the tank positioned where I want it then pack in more foam to hold it in place. A regulator will work but why not just put the tank where it belongs? It's easy and a bunch cheaper. Kinda one of those no gimmick set ups.
For those of us that still build our planes tank location is one of those considerations we think about before the glue bottle is even opened up. For those that ASSEMBLE an ARF the Rape and Pillage is often the best way to do something.
Another way of doing it is getting a pumped engine. They don't care where you place the tank. The Saitos are great engines but they still don't have a pumper in the line up that I have seen.
