Now that I've showered my new toy with praises, I'm trying to solve a fuel draw problem. If you scroll back a little, you will see a photo I posted of the Knife sitting in front of my Aresti and Avistar. Note that the TT .46 Pro is all the way forward on the rails. Also note that there is no fuel tank visible (it's in the wing!) Because of this, the engine has a long way to draw fuel.

Since taking that photo, I've attached a Macs muffler (the small semi-tuned pipe). I've become better at hovering, but the engine doesn't like the pipe and the long fuel draw. It has a problem leaning out during a hover. To solve this, I put a 4oz header tank between the engine and the wing. While I'm not convinced this is the real answer because I believe that the fuel is still ultimately coming from the wing tank, folks tell me this will solve the problem.

This introduced a new problem - the header tank foams badly even though it has a nice layer of foam surrounding it.

So, what's the expert concensus:

1) Use more foam on the header tank?

2) Ditch the wing tank and use an 8-10 oz external tank (with enough foam, of course!)?

Inquiring minds want to know! Gotta solve my fuel draw problem!

Thanks
