High Tank Problem

OK, back to the P-7. After examining the fuselage, and spending a couple of hours (and a few beers) in contemplation, I have reduced my options to two choices:

1. Go with Tony F's solution. I bought a Du-Bro 16 oz. tank, and it does fit up in the nose much better than the tank that is provided with the aircraft. Examine the attached pics, there is a 1/2" difference in the mid-line of the two tanks. That is significant. The bottom of the tank is the datum. (Because that is where it rests in the fuselage).

Using this tank, it appears to be possible to get the centerline of the tank within approximately 1/2 " of the engine C/L. Not ideal, but in the ballpark.

2. Go for the upright engine installation. This would be a sure bet to establish the correct geometry. Major engineering project, which flies in the face of the "keep is stupid, simple" philosophy. I would like to avoid this scenario if possible. But if that is what it takes, so be it. That is why we call it a "hobby".
