No need to Be sad Mr Cox,.. It's 100% real Dummy! The tank is balsa along with the crank case turned on my "hand-drill lathe" crankcase screw bosses are bamboo skewer sticks, crankcase scout is a snip from a soda straw. Needle valve was a toothpick with a 1/32" ply disk installed and 1/2 a ball point pen spring (streached) But,. it couldn't survive MY kind of flying/crashing, so I replaced it with 3/32" fiberglass kite rod. I'm also sorry I installed see-through exhaust ports on that small .020 cylinder,.. had to CA it back together twice now The "secret" to the illusion is the humble 1 gallon milk jug. When punched out with a hot brass tube (or for 020 a 7.62 x 39mm used shell casing) they can be carefully cut slightly oversized, then mounted on your drill-lathe turned balsa cylinder & correctly (after first coating it with Pacer Formula 560 canopy glue,.. about the only thing that holds milk jug) Once dry, You place the cylinder back in the lathe, & lightly file with a jewlers flat file, followed by the triangular file. Milk jug is almost the perfect thickness for 020-049 Cox fins, AND, it's FREE! And you have seen it before Raymond,... here http://www.rcuniverse.com/forum/fb.asp?m=3810198 After a nasty break up, financial woes, a major heart attack, and quad bypass surgery,.. I'm just finishing it up Here's a mini, hurried semi-how-to on the milk jug fins, and more photos of the Foamin'20. http://www.rcgroups.com/forums/showthread.php?t=861739 If you go there make sure you watch/listen to the small video. who says electrics have to be "quiet" and you'll know what an .020 would sound like as a 4-stroke There's also a photo of My "Demon & Rice" .23 ignition engine, installed over my 1939 Scientific Mercury Jr. geared 400 motor in there.
