Here's a hint:

Clown racers with (unlimited) 15's can go 40 laps or more on ONE ounce.  So a little more than a 3/4 of an ounce should be enough to start it yourself, run out to the handle, and fly 16 laps.   A half-ounce if somebody starts it for you.

Check the Brodak web site or make the tank yourself.  It isn't that hard to make.  DOC Holliday

There is a ready made tank that fits between the engine and the firewall, and some, wanting extra fuel cut a hole in the firewall and pass the tank through it. Two good people to ask: Frank Carsile and Joe at Sam's Stuff and Hobbies.

Building your Perky is a good chance to learn how to make your own tank.

Fashion a wood block the size of your tank out of pine or some such soft wood, then wrap sheet metal around it.  Brass shim stock, .010" is what I always use.  The Perky is a good "tank trainer" since it doesn't need to stunt or go inverted.

You get four sides with one continous wrap, the add the two end plugs.

The third picture shows a tank form being sawed to size & shape.  The dowel was inserted 'cause I was chicken to get my fingers in the buzz saw.

About a dozen of our club members are building Perky's this winter. I couldn't find an acceptable tank for mine locally so I built one. Notice I lowered the motor mounts 1/4" so that the engine is mounted on the thrust line, where it should be.
