• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Fuel level gauge and flop tube

I have installed a flop tube in my fuel tank for inverted flying. When having a flop tube you can not install a normalelectric sender for the fuel quantity gauge, because the flop tube can be trapped, so you have to use a sight gauge.

Now asight gauge is not a good solution, as itcan be verydifficult to read, so I wonder, if it is the only way. There are some capacitance systems on the market, doing away with the float. Perhapsa possibility, with theprobe placed near to the wall of the tank?

Has anybody tried that or some other means to get rid of that sight gauge ?
