Hi In my judgement all IC engines should ever have Metal Piston rings. Just to avoid the said Problems. In the end you will have to constantly change the Viton Rings due to wear. No matter how polished your Cylinder surface will be. This does not happen with precisely made metal rings. The...

Dear Mr.Rupnow What's up with you? At first you are crying around cause you can't get your engine to run. You never take the advice you have been given from other builders. You ask for help but always do your own Thing. You tell us day by Day about simple things you get stuck with. A lot of...

I used the one way bearing that you see in the attached Picture. The inner diameter is 8 mm, the outer is 12 mm. Bought it at Ebay and payed 3,99 euros a piece for it. And i put a ball bearing on each side of it, just to support the whole construction. And yes, the shaft is hardenend.

So, what is a "Sprang-bearing"? I can`t find a translation for it, not even Google can.

Hello Guys Thank you very much for the nice comments. I appreciate that. Sure i can give more detailed information about the Kickstarter and the Ignition system that i made. The Kickstarter is mostly made according to the Plans from Randall Cox. I replaced the no more available so called...

Hi all together I`m presenting my fresh finished "Hoglet-V2" Engine, another one Made in Europe. This Engine has Cast iron Piston rings, Aluminum Pistons and a precision steelpipe (no hydraulic pipe) as Liner. All parts were made according to the Plan from Randall Cox, except the parts which...

Brian I would Encourage you to make a valve in two pieces. I always make my valves this way with good Results. Give it a try. Stefan

First of All, short runtimes! And enough oil in the fuel mixture.

Gentlemen I wonder what this thread is about. It started good as a thread about testing CDI devices. And Now it drifted away to a philosophical thread about the natural wonders of the Universe and the mysteries of Electronic in specific. I thought it could be of interest but Now im out.

The Metal parts of the elbow cap as Well as the Metal "shielding" around the sparkplug wire is the only ground connection of the whole CDI ignition. RCexl and most of the other manufacturers build it this way. If you remove all that and fire the ignition you will most probably kill it, because...

Runs and sounds like the Real engine! Superb modeling, fine Details, very Well done. Congratulations. Stefan K.

Hi Ray I would prefer Option 2.Checking All the boxes by dragging the cursor over them and change them all with one click. In real life one will Not change These numbers too often. So it should be done quick and easy. Good work! Keep on.

Really?? What a comment! "Go to Hobbyking and buy one"? I believe you didn't get me. It's not about just having or buying an ignition. But anyway, i stop talking about this now, knowing its another worthless comment. Nothing But warm air......

Johan The last post is over 14 years ago. So you can expect that the promoted Website has deceased a long time ago.

Hi Giel The Links to the Websites you Provided are already ancient. And so are the ignitions. And most of the members here should already have seen them. Either they are way too big to fit in a Model engine or they simply dont have what has already been discussed here. Im interested in the...
