Tiny PJ and plane

Hi,

Go to the pulsejet section and under blueprints you will find ( #17 )craftplane.

The plans are for the pulsejet described by Mark, and are free for the downloading, so why pay for them on Ebay ???

Variable cam timing

Hi Larry,

The 1980 Alfa Romeo 2L spyder used a twin variable cam engine and was the first production car to use it.
US Pat. #4,231,330

Honda then developed the V-Teck system.

re: aluminium powder

Hi metiz,

I would say that it will be a lot cheaper to get El-Kablooey to send it to You than to use paint.

Silver automotive paint with the appropriate thinner works well, but is expensive.

re: aluminium powder

Hi metiz,

I would try a paint supplier, and ask for aluminum flake that is used as a pigment for aluminum ( silver ) paint.

Or:
buy some aluminum paint and wash the resins out by using an appropriate solvent.

Hi Rufus,

Wippe also means balance, which is more descriptive of the mechanism described.
