Hi, I have seen a microjet for model aircrafts. It used regular JET A1 fuel. = I think that the size of the combustion chamber was about 2". Don't = remember if they started it with a DC-motor or pressure air.=20 If I can find the newspaper article, I'll get back. Don't remember the = price either, just that it was very expensive. 73 SM4RAN - Attila -----Ursprungligt meddelande----- Fr=E5n: Jeethu Rao Till: PICLIST@MITVMA.MIT.EDU Datum: den 5 juli 2001 10:39 =C4mne: [OT]: mu Jet for RC Planes ? >Hi, > I had followed the thread on H2O2 some time back. > I've got an Idea which might sound too Crazy to work. > But there might be someone just as crazy as me, who might > have tried this before. > > How about a Small Aluminium pipe(2" Dia) with a small > DC motor powering a small Propeller to force air through > the Pipe.
