norvelle engine
this might be a really dumb question but norvelles are still made arent they? they arent like Cox engines or anything. i could just go down to my local hobby shop and pick one up right?

RE: norvelle engine
I *think* they are, but I don't know if thy're being imported at the moment. Sig is supposed to be working out details with Norvel to continue carrying the line.

RE: norvelle engine
Norvel engines are in short supply and waiting for Sig to sort supply issues out with Norvel is getting tedious. If you need an acceptable throttled 1/2A you might as well just get an AP Wasp .061.

RE: norvelle engine
I've heard locally that a couple of guys flying the .061 found them to be real dogs initially. But after 15 - 20 tank fulls through them the came to life. These guys think they just require a lengthy break-in. Supposedly they are little screamers once broken in, but only time will tell about how well this engine will do and it longevity.

RE: norvelle engine
All of the Norvels I have flown were pre-RevLite. By the time the RevLite came along I had moved to VAs.
We had some trouble with the nickel peeling off the cylinder walls. It did not happen with every engine. We were running little glass props and 5X3 black Cox props cut to 4&1/4, so they were turning up pretty well. Whether or not the problem would have occurred at 25,000 I don't know. Maybe not.
Speculation was that the problem was possibily related to not cleaning and properly preparing the cylinder prior to plating it. Both the cylinder and piston were usually ruined when the problem occurred.
Never-the-less, I regarded them as pretty neat engines, especially considering the low cost and we had a ton of fun with them.
So, I would not particularly worry about the AP being like the pre-RevLite Norvel, if the quality is equal to the Norvel.

RE: norvelle engine
I've run a little less than 5ozs through my Wasp .061, and it's already holding a pretty lean setting. It "feels" or sounds like it can still gain a bit more with further running. I didn't want to push it too soon, so I had it one or two clicks back from the leanest setting it would take before sagging. I'm really happy with it so far, and I plan to buy more down the road. I think as long as you mount it on models weighing around 1lb and less, it will prove to be a fine engine. As far as I'm concerned the collectors can keep their NIB Norvels.
BTW, I was reading on the Norvel web site (yes, someone's still paying to keep it live) that in 2001 they borrowed about $2M for new CNC machines. I wonder if maybe they defaulted on that loan and had to sell off the equipment. That's a huge debt to try and pay back by selling 1/2A engines (unless they were making other products, too).
