Hi Bruno,

Right F***ing on !!!!

Having been around computers since the Altair / Imsai days, I can totally agree with Your thoughts and observations.
As far as Your language " problem ", I can appreciate it fully, since I am a fellow sufferer of the same affliction.

Hi Nitromen,

Go to the pulsejet section and download the tempest II german plan.
This is easier, and gives about 8 pounds of thrust.

Fueling

Hi anders,

I am thinking of using !/16" OD. X 1/32" ID. tubing, which will contain less than one fluid Oz. of fuel weighing less than one ounce.
A reasonable pressure will be required to force the fuel through the thin line at the proper rate and into the tank on the plane.

frustum spreadsheet

Hi,

I use this calculator which uses the classic formula.

If You enter the three values, you get the frustum volume.
If You enter only one diameter and length you get the volume of a cone.
If the diameters You enter are the same value, You get the volume of a cylinder.
