Lite Machines used to sell a .061 powered fixed pitch heli (LMH-100 I think). It's not sold anymore. As your 1st glow powered heli, I'd recommend a .32 or .50 powered machine. The smaller they are the harder they are to fly for 2 reasons: 1) not as stable, 2) harder to see. Orientation is one of the hardest thing to learn with a heli and the little ones don't offer much to look at from a distance. Also, you'd have a hard time finding part for an LMH-100 (Spare parts are a very important ingredient when learning)
I looked into a Lite Machines .061 back when I started and found out that once you figured everything needed to be successful they were just as expensive as a Raptor and offered so much less.. I ended-up getting a Raptor, which I still have, It has about 90 hours on it and the OS .32 on it is still going strong.
Honestly, there are so many inexpensive electric models these days, I would be inclined to go with that as your 1st one will have to be rebuilt a few times before you really get the hang of it. Might as well go with something cheap / easy to fix and upgrade later if you decide the heli is for you. Also, the glow engine adds another element of challenge to an already very challenging thing to learn..
You can do even better on price by finding a used one. Helis ar so difficult to master, the reality is that a lot of (If not most) helis are flown only a couple times and the guy gives-up. Many end-up cheap on ebay..

For a comparison between weights I think both engines should have the stock muffler on. The Enya then weights 145g with the old, smaller, muffler and even more with the new muffler that is delivered if you place an order today (i.e. the same as for their .15 engine, the muffler has a double set of threaded holes).
In terms of performance i get around 14500rpm on an APC7x4 on the Enya, which corresponds to about 0.15Hp (according to the ''power calculator'' by Peer Rivers).
The Norvel spins a 6.3x4 at 17500rpm and puts out 0.18Hp on the same 10% Nitro fuel.
So in terms power/weight ratio, the Norvel has more than twice of what the Enya can give, so the advertisment is actually a little modest...
Enya is also the lightest 09 engine (including muffler) that I know of, apart from the PAW 09 then, so it is even more favourable to compare with other engines like the OS LA series for instance.
This doesn't mean that Norvel is the best for every application but in terms of power/weight and ability to rev, they are pretty outstanding in my mind.

As another data point I found through my 400 + flights using the Enya,
I get 15,500 RPM swinging a MAS 8 X 3 with 15% Nitro and a colder plug. "Thrust HP" says that's .327 HP and 2.78 LBS of Thrust. ( I think it's a little optimistic but it does pull my Little Extra straight up so it's at least 32 or so ounces of actual pull)
Like many engines, the Enya is sensitive to the props you use. After much experimenting I found the APC's wider blades (Perhaps more efficient?) tend to overload the engine and keep it out of the 15,000+ RPM "Sweet Spot" where it makes maximum power. I also use a light "Tongue" Muffler that weighs just a few grams (1/2 the weight of the Enya Muffler)
Again, not to take anything from the Norvel. I think both engines excel at what they do best

Klondike, glad you're getting this fine line up & running again!
However, I along with many here don't like the whole 'registering' thing on the site. I find it invasive and unnecessary, especially when compared to the majority of RC vendor sites. Do yourself a favor and just post the prices, less controversy/drama. As stated earlier, 'You catch more flies with honey than vinegar'.
As for ARFs, get an agreement with Andy Clancy to reproduce his fine line of Bee aircraft. They are sorely missed, and would fit perfectly with your engine line-up! [8D]

Are you referring to NV 049 Aero?

Yes, it is Aero. This engine has been discontinued. We have some in stock, but not too many- being the least expensivethey are selling fast.
049 Aero is on the web site, take a look

RE: NV Engines (formerly Norvel) are returning?
Most of the discussion so far has been about the smaller engines. I have the AX-40 and love it! I would like to see a 50 size offered. That size would not have to compete head-to-head with electrics and has a huge selection of ARFs and kits available to it. Even a 40 is not as usable as a 50 size range in the ARFs arena. JMHO.

Well, the .40-.50 is pretty well cowered by all the other brands already. While in 1/2a the Norvels are truly unique.

049 is not plannedbe produced in the near future - 061 is more popular. The next engine we are working on right now is 46.

You can see alldifferences at the web site - 049 Aero is smaller than Big MIg 049, no muffler, and shorter crankcase

Put me on the list to send specs/pricing/availibility. Any chance of edging into the .60 sized market?

Yes, it is bored-out AX-40. No specs yet - too early.

I like your humor :-) However we are planning to change this destructive pattern by making the planes out of new material that is virtually indestructable. We are doingsome tests right now.

I'd be happy to go back to the earlier, smaller cylinder profile with Revlite finish. I know some of the transitional cylinders were like this when Revlite came out, I'd love to have more of them. The larger cylinders don't offer any advantage I can think of other than looks.
