- Well, no, but I wanted to clear up some things about .049's.

- Okay, here's what you do. Use a normal tank with a balloon inside.
- The idea is to have the balloon fill the interior of the tank without
- inflating. The balloon is held in place by the tank cork. Then
- instead of clunk and vent lines, you use a straight tube going to the
- lower back of the tank, with notches cut through it (and smoothed so
- as to not cut the rubber). You just cut a small hole in the outside
- of the tank for a vent. When you fill the tank, first suck the air
- out from inside the balloon, then fill away. It really works.

- I've never had a QRC or Texaco, but I assure you that a Black Widow
- has an inverted fuel system.
-
- You can also buy tank mounts for TD 049s that handle inverted flight.
- That will give you more power than a Black Widow.
