I like this idea as well. I think we need to start a standard to compare engines. I think it was a while ago but failed, or maybe i was just dreaming. Anyways right now i am working on a program that when coupled with data from UFlow determines Thrust and a thrust versus time graph. Right now i am u...

I would like to thank everyone for the help because i have finally gotten it to work. The problem was the transistors. I tried two brand new ones and both were duds. This led me to believe that the transistor wasn't the problem but i just tried another one and it works. Questions. Is there another e...

Thanks i would appreciate it. I now know that my circuit is the problem because i bought a Accel Super coil that does 120.000 plus volts. I can't understand why the circuit works for light bulbs and speakers but not my coil. When Hook a light bulb up to the circuit and turn my freq. down the light i...

My transistors are brand-new and aren’t the problem. I guess i should have said that the speaker does get much louder but it came out long. Even with the darlington circuit I can't get any decent sparks. It’s really starting to frustrate me. I have finished my big turbo jet but can't start it ti...

My trick with sparkplugs is if it is to be threaded into thin stainless I just drill a hole and thread the sparkplug into which gives a nice fit. If the plug has to go into something thicker I just re thread the sparkplug to pipe thread and call it good. So far it’s worked for me.

I have little experience in building electronics but have am taking AP Physics and we are studying E and M right now so i understand the basics of all the components and can use math to solve problems I just have had any practical experience. I am using an analog needle multimeter because my digital...

Thank you for the response and ideas. I will check the resistance later when i have time.

My battery is a heavy duty car battery thats fully charged. I will get back to you on the make and model of everything later as well.

Thank you.

Well I have done everything that you guys have suggested and still it will not work. The resistance in my coil is zero so that’s not it and my circuit works. I can hook a speaker up to it and go from a slow click click to a buzz to a high pitch squeal all just by turning the potentiometer. I am ru...

Thank you for the comments. Yes i built all three and all three work when hooked up to a speaker so i assume the circuits are working. I have switched between two batteries. Both were chareged and one was new so thats not it. So i think it is my coil but i switched coils and the same happend so mayb...

Thank for your comments. Here are the circuits that I built.

I MIG weld all my jets. The welds may not be perfect but they are by no means ugly. It just takes a lot of pratice and patience to get used to it. Once you get the technique down its a piece of cake.

Ok so my ignition setup right now is a piece of junk and never works so i decided to build a electric circuit based on a 555 timer chip. I found many plans on the Internet and built many of them on a breadboard. The problem is i can't get a spark bigger then around .1 mm The circuits work but i can'...

Ok sorry if this si repetative but i have been missing alot on the forum lately and didn't want read all the pages to catch up. Here are my questions. Where, what city and where. When, time, when people will show up Any other info i need. Like when people will meet where and if there is room to slee...

I was wondering if any one out there has any information realting to motor jets. I have a couple big electtric motors big fan blades and lots of metal and was hoping someone could supply me with some basic information realting to this subject.

Thank you for any help.

More pictures and video for your enjoyment. This time at night. I ran the engine for about 20 min straight before turning it off. Never once did it hick up. But I do think my neighbors were wondering what all the noise was. Something interesting is that the exhaust is very cool. I can stick my hand ...
