1/8 Inch Tubing Caps

Fold the tube over on itself, and put a small alligator clip on it.

Tim was talking brass tubes, I think, not silicon. :-O

But if we're allowed to imagine a silicon extension for the brass tube, then a fuel dot would work and be a little neater than the alligator clip.

You are correct. The brass tubing means that after folding the alligator clip is unnecessary -- but then you land with an empty tank, and your life gets complicated.

Eh. I didn't know about those. I'll have to take a look at what the LHS has to offer (Or make one from billet 6061! Now _that's_ cost-effective!)

If you're willing to live with a silicon extension, you could seal it with a machine screw. Not sure what size, but when you find it you could beef it up at one end with a washer (soldered or brazed)--just to make it a little easier to find when you drop it.

Those little guys are in common use with automotive carburators and vacuum systems. Try a auto parts store (the real kind, not a PEP Boys or the like).

Try looking in a junk yard for a rubber vacuum line cap. Most c ars have several vacuum lines plugged off with rubber stoppers.

Failing that, a piece of fuel line plugged with silicone caulk/glue ought to work well.

DOH! I think that's the best (cheapest, quickest, dirtiest) solution yet.

Way to go, Randy!

I think I'll go with the fuel dot -- control line models are more fun to fly if they look good from the control handle; a fuel dot means that there won't be _anything_ out of place in the air.

But if I get lazy, or if the LHS doesn't have fuel dots, maybe I'll change my mind...
