Pulsejet powered World Models TameCat RC plane, maiden flight
After a few delays and some last-minute changes to the fuel system so that the engine could draw fuel up the 8-inches between the tank-bottom and the spraybar, the first flight of the pulsejet-powered World Models TameCat has happened.
It's sure not lacking in power (10lbs thrust versus 7lbs flying weight) and it was damned fast!
Despite being a mild-mannered pussy-cat when powered by a regular glow-engine it's very apparent that under full jet-thrust I'm going to have to cut back the elevator throw a little. The TameCat is such a big pussy to fly once the power's off though - landing is a breeze!
The engine switched to lean-mode short-cycling when I pulled high-G's in the second turn so I'll have ti increase the fuel pressure some more and reduce the size of the fuel-metering jet so as to reduce the effect of hi-G's on fuel-flow.
With luck, I'll get the changes done and fly it again tomorrow!

And if you like what you see, tell World Models that they should offer a pulse-jet version with a few modifications. I'll let them have the necessary changes. This is the *perfect* pulsejet trainer!
