flyingvranch,

I used the same exact technique, and even the same sanding wheel that you did. I think the patience part is what I was lacking. I kept grinding a little bit, and then putting it on the plane, then taking it off and grinding it some more. The last try I decided to make it my last, and ground out about a 1/2 too wide by about 1 1/2 inches too long. Luckily it is on the inside of the plane, so you can't see it when the plane is sitting on the ground. Oh well, hind site is 20/20. Next time I will take the extra 10 minutes.

That .40 of your is really efficient! I am lucky to get more than 10 minutes on a full tank. I set my timer for 10, and when I bring it down I am lucky to get a couple of cranks of fuel back out of the tank. I haven't ran it dry yet, but I am sure that I will. I have to admit that I have a lead thumb. I just love to see her fly by at mach 10.
