Thank you all! --- Quote from: dsquire on May 05, 2013, 04:23:24 PM ---Looks like it passed the test today. Any idea of what RPM you were able to reach? --- End quote --- Yes, big relief for all. :thumbup: RPM Turbine is 11.000, and 2.500 at the output, at last 1.200 on the wheels. Best regards Kurt |

Well, that was something! Just had a test run. With reinforced spring in the clutch. And new gear reduction 1:4. And 1 kg of lead weight for the lacking aluskin. First the good news: - The clutch works! - The racing car - and it's really one - sprints with about 8 km / h as devil. Even uphill! Madness! Now the other side: - Turbines also appear to be sensitive to water hammer. The steam dome - if one can even speak of it, is more of a tiny dome - and is backwards. When starting up there is water in the pipe, and indeed not even a little. Since I have still no superheater, the water comes in as 1:1 into the turbine. Now I have an ugly noise in that part, metal on metal. The revision will show. Pray with me ... - The RC and the receiver are going to be melted. Denial of service. But i have enough spare spot. - The butane tank temperature is a minor problem. But not a real one. What remains to be done: - Installing a superheater and hope that the turbine / bearing withstands the temperature. Furthermore, that the present performance remains despite then superheated steam (= less kinetic energy). - Installing a three gear clutch. I have to extend one of their axes. Toi toi toi! |

Instead of drinking for Father's Day today in Germany I have built the superheater, model immersion heater - cozy after the melting of the FB. Test follows. |

Keep your eye on the copper super heater they burn out real quick a better solution is stainless steel tube use for hypodermic needles ( vetenary ) that what I use for my loco's for info I use 8 elements bent up like a trombone of 5/32 dis. this can be bent to a .5 inch rad with tube bender good work on the cars I do like the Audi I am interested in your forum name translated its baffle plate , maybe its got lost in translation from German Stuart |
