As far as I know, yes, Norvel is not going to be making any more engines. I've been in touch with Justin at Sig all along and the word is pretty final. Only if someone came along and bought the rights, tooling etc. The Chinese might do that but till then,,,

However, I was lucky enough to snap up a good selection of old and new inventory that I plan to offer for sale this winter. The intent is to make up diesel heads for the entire line. I have threaded head blanks of the right size for all the Norvels from the .15 to the .40 and finally, I'll be able to make proper heads. Early designs used a contra-plate instead of contra-piston. It worked OK and allowed some experimentation but eventually caused problems.

My entire year has been spent with personal/health issues that are coming to a close. I hope to be back up to full speed by the New Year and by next spring, a few Norvels of all sizes will be available,, at least for those that want one. The problem of plugs for 1/2A, including Norvel, has been solved with my article on RCU last year on how to make and adapt to take, turbo plugs. Unlike stock plugs, turbos give you back all the original power that you got with the original plug be it Cox or Norvel. I'll be making a small batch of these units, again, for those that need REAL engines for their small planes.

Status: offline 		Wonder how long it will be before RJL gets the rights and starts making Norvels?

I wish it were as simple as calling up the factory and getting more engines for a supplier. When a factory closes like this, talent moves on with their lives and go on to greener pastures just like we do when we get laid off here in the states. With Russia, you never know.... it could have been the Mafia that closed them down, or maybe they had a hard time getting paid in a timely manner? Dunno, it's not important now. We can just hope that the ChiComs get their poop in a group and improve the CS/Brodak engines.

That said, Brodak had a really nice Russian made 1/2A at the Toledo show. Don't know what the story is there.

Status: offline 		Dave,

Thanks for the tip. I took the original Brodak steel/iron .049 and installed an AAC .06 set made from Wasp components and got 19.8K on a Tornado 6 X 3.

http://www.youtube.com/watch?v=qHQhD1PpJUQ

This is with a muffler and effective throttle.

Well, the Revlite version throttled better but for a loss of 1000 rpm at the top. http://www.youtube.com/watch?v=XYITm-hTggM

So it's good to see that Brodak has gone to modern materials. We have hope. It looks though, that they've retained using a standard pug. It was found that using a Norvel .074 glow insert or converting to a turbo plug could give you an additional 1000 or more rpm with no other changes. Slotting the case and crank ports produced another 500 RPM. Ought to be easy to do with the new Brodak.

I sure hope that if they make another RC version, they make it .06 and include an adjustable airbleed.

But look, the new one has a proper nut and washer to hold the prop on. Neat.

Status: offline 		Anyone know of a source for glow plugs for the .074 Norvel engine. I'm down to my last one. Also is there an insert available to allow the use of a standard plug. I plan to take one of the burned out plug drill it out and tap it for the 1/4-32 std. plug. Any thoughts will be appreciated.

Status: online 		Unless you can find a hobby shop with some sitting on a dark shelf , norvel plugs are non existing. That said do a search for Turbo Plugs here in the 1/2A forum, AndyW did a thread showing how to. Useing turbo plugs in a Norvel head button will maintain power wereas useing std plugs you will lose power.

Status: offline 		If you absolutely have to have stock Norvel .074 heads, they do pop up on "That Great Auction Site" now and again...... For $30+ a piece!

If you don't mind a long wait, order a Hypercolor Turbo Head from Tim Wiltse. They are really nice IMO.

NORVEL sold an adapter that allowed the use of a standard plug, but the performance was poor. Many of the folks here use a combination Galbreath head and NELSON plug. In most cases, the engines run better than with the original NORVEL Freedom plug.

Heads and plugs are available from Larry Driskill at Kitting It Together.

Status: offline 		Norvel's starter spring is an exact fit to an AP .061 Wasp. I have the Norvel .061 with a spring and a Wasp that didn't have one. Unfortunately a spring is not available for that engine. I emailed Global Hobby to see if one is forthcoming.
Here is their reply.

I'm sorry, but we do not have a spring starter for the AP .061 engine. I will forward your email to our product manager, though, regarding your interest.

I tried to find a prewound spring that I could modify at hardware stores but had no success. So, I took a length of .047" music wire and with a few hand tools, wound a pretty reasonable functioning
