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
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,
Dan McEntee
