     Hi Mike;
     
  These days eBay is the typical source for either engine and limited parts availability. You can check Cox International and EX Engines on eBay or direct for some Cox parts but I don't think either are building anything new. Norvel is now known as NV Engines and you might have to google that to find a website.  The parent company for Norvel dropped the engine line because they were too busy with other business and products. They sold off the engine business but kept the rights to their name so the new owners changed it to NV Engines. You can search that out on Stunthanger also, where people have ordered from them directly, I don't think there is a US distributor. As I recall, their web site takes a bit of work to navigate , but service was still pretty reasonable. I would be concerned that the current situation over in Europe and Russia may affect things. I don't think I have ever seen or read of anyone using Norvel engines in free flight model, and don't really know why. They make considerably more power for their displacement , but may be a bit heavier because of the ceramic materials used in them?? Just guesses on my part. I still haven't run across Navajo plans yet either, but still looking.

             Mike, years back you couldn't get any parts or engines from Norvel. Sig discontinued them and essentially many of us sought out to find whatever parts we could. When NV came into fruition, a fellow named Alex came onto Stunthangar and announced the new name. Currently, if you do go to the NV website you get a message indicating a non secure website or something on that nature. Alex was the go to person and another fellow Dimitri would invoice your items and get them on their way. I remembered the e-mail address for Alex as he said he was the US distributor which as
                  Klondike17@juno.com        I've contacted him in the past but it's been a while.  Here's the link to NV http://www.nvengines.com/    I would really consider contacting Alex and find out what is up with the site prior to purchase. He was always good to me in responding and getting my parts quickly. Ken

Thank you for the help Dan.  If you run across those plans that would be great but I am in no rush...just something I want to build for nostalgic purposes.

        Try the classified sections of the RC forums. I see both makes on RC Groups and RC Universe but more so on RC Groups. I bought two Norvel .061 and a Norvel .074 from the RC Groups classified.

     This is more or less what I remember reading. I think Sean may have bought a couple after the new guy took over. We carried Norvel engines at the hobby shop I worked at when SIG was the distributor and had plenty of people bring them back as deflective because they were so tight and you could not convince them that this was normal and OK. They would not read or follow any instruction at all. That is how I got my first few, the shop sold them to me for cost rather than send them back. SIG eventually dropped them for more or less the same issue, and the trend continued with the Sky Baby and Hexdrone from Bratco, and then SIG donated the rest of their inventory to KidVenture because we could deal with them that way. I may have missed something somewhere but I don't remember ever hearing of anyone flying Norvel engines in Free flight competition, and just don't know why. Some guys were using the VA engines that preceded them and were very similar in 1/2A combat. The .061 seems to be the most popular, but is not, of course a true 1/2A but is 1cc and there are some 1cc stunt contests and designs floating around. I think you could fin a largeish 1/2A design for the Norvel, .049 and maybe a smallish class A design for the Norvel .061. There are still lots of TD .049's out there though and they can be detuned a bit and they may be more tp your liking. Any Cox reedy engine with the proper cylinder/piston/ and head can also get you some decent performance and reliability for just fun flying also. The later generation of engines had 4 mounting holes on the back plates so you could use a separate tank or light pressure and a cut off timer, or even the old fashioned eye dropper tank will function with them. For just fun flying, you do have a lot of options.
  Good luck and have fun,

          Mike on another subject, Cox plugs are over the top in terms of cost. In addition, they have a relatively short lifespan especially a TD running on 35% nitro. I use Nelson head adapters and Nelson plugs for the Norvel and on the Cox I use turbo plugs. The Nelson could also be used it just requires a bit of fiddling with head shims. The initial investment is truly cost effective. Greg from Kamtechnik provides excellent quality adapters in either or versions. I use the .020 adapter with terrific success. https://kamtechnik.com/product/ktk-11/
