About a week ago I got two NIB Big Mig CL Startups. I finally got a chance to run them today. After the 100 turn & oil ritual I put them on the bench and started them up. Each ran 15% nitro, three head gaskets and a Norvel glow head and got about 4 onces of fuel each. They were run on 5.7-3 and 6-3 props. They are both comfortably doing 19.5k and I've seen them go to 21k. I suspect a bit more after more running. And I'll try Galbreath heads then too. I did have some problems with a tank and had to resort to a wedding bubble substitute but the startup tank is ok now.

Ultimatly I'll shoot for 8-4 or 8-5 props at about 9-10k , sort of hotrod texacos

for sport r/c work.

I'm still looking for two Norvel rc carbs.

regards - Steve B.

Thanks,

IMHO, there is none!

Unless, you can run across one in a garage sale where the seller does not have an idea what they're currently bringing.

What are people's opinions on an OP Hornet -09? Or, is there something that will bolt in for the Norvel? I want to build up a Herr Engineering mini-SE.

I wouldn't count on SIG having many parts available -- even though they list them on their web page, they likely don't have any in stock. Good luck!!

Has anyone got any recommended substitutes? Getting one that bolts in to the Norvel bolt pattern would be nice, if it's available.

Status: offline 		The Norvel .074's are gone. You can get them on ebay at really high prices ($100.00+), purchase Lite Machines .074 heli engines and try to convert them to plane use or you can go electric and be clean and happy. I don't have any experience with the AP .09 or a Thunder Tiger .07. If you get one you can tell us how it goes.

The Norvels made me think about 1/2a in a whole new light. I hated cox engines when I was a kid. The Norvels act much like a modern .40 size engine, even on 5% nitro

Steve B., I don't think your Norvel's will be happy at 8000 rpm. They are not timed to run at that rpm under load and may overheat. I am interested in how you do.

Status: offline 		Thanks for the update, Skypilot. I haven't been paying attention to them.

As it is, I have a Norvel .074 and a TT GP.07. The Norvel is in a home-brew glider and the TT is not being used in anything. maybe I'll replace the Norvel with the TT and then drop the Norvel into the Herr Mini-Somethin' Extra.

I've run both engines and the TT is not at all as strong as the Norvel. The TT is for glider assist and light duty. It just means that I will have to re-build the front end of my glider to take the TT GP-07 (narrower mounting dimensions).

I don't have any experience with the Hornet .09. I just happened to come across it on the TH website.

Status: offline 		I've found that, for some reason, the Norvels actually tolerate a wide range of props. Here, http://www.youtube.com/watch?v=af4dQNa60_w we have the .074 doing 11.7K on diesel on a Cox 8 X 4 prop. This IS on diesel though, so that may have something to do with it.

Here, http://www.youtube.com/watch?v=PRn5i6Knisw in a similar fashion, we have a dieselized, .06 doing 10.5K on the same prop, on diesel. No issues with idle and transition.

However, here, http://www.youtube.com/watch?v=_pN6-rgXEFk we have a glow .15 doing 10.5K on a Grish, Tornado, 10 X 4. No real issues with idle or transition or top end. Smooth and steady. Note that with the larger prop, we were not overcompressed as you might think we would be. Generally, when you put on a bigger prop, you need to retard ignition timing by reducing the compression ratio. Despite the larger prop, we saw benefit by increasing the CR. We've taken stock head buttons and shaved them down for similar gains on large props.

The Norvels somehow, manage to break all the rules.

The LiteMachines Norvel .074s have some neat, desirable features. Short block with brass bushings on both ends of the crank. However, for some inexplicable reason, they don't throttle as well as stock, .074s even with the addition of a throttle with an adjustable airbleed. They DO throttle very well with LM's exhaust throttle. Why all this is so will be looked into in due course. The upside is that you can get new piston and cylinders from LM by buying the whole engine at the same price as a PL set. That is, if they have any left.

Status: offline 		I really liked the Norvel's. I'm sorry to see them disappear from the USA.... but I do have to say that one should not stick one's finger into the prop of one of those beasts when running an SPC prop. Absolutely perfect lacerations (I didn't blunt the edges with sandpaper like I should have). If I had had a wood prop on there, my fingers would have only been bludgened instead of lacerated :-D

Hopefully my LHS will have one left over in his stock for me. I'll find out tomorrow. yeah, I liked the Norvel - and also learned to respect it as well

Status: offline 		Sorry for a beginner question -
I have BigMig 0.061 with standard glow plug and head (I think it is called Freedom something) -
now I lost my glow plug clip for it and local shop does not have them.

1)Are they the same as Cox Black Widow ones?

2)Anyone knows where I can find them online (preferrably UK but not mandatory).

Thanks!!!
