I have decided to go with a norvel .061 engine for my latest project for flying in the back yard.I ended up with about 20 cans of cox brand fuel in a package deal at a local swap meet that i had no use for. But i was wondering if this fuel would be ok for a norvel. The cox fuel i have doesn't list nitro or oil content. Would it be ok for a norvel? Thanks for any input. Tom

Sure. I don't know the content either, but if it's OK for Cox, it's OK for Norvel.

Yep it'll run and do no harm. I tried Brian Cooper's 1/2A Fuel in a Norvel .061 yesterday and it loved it. Uses 25%nitro, 20% Oil 50-50 mix synth and castor. Went like stink. Methinks Cox is about the same.

Red can or blue can? Red can was standard fuel and blue can was racing or high perfromance fuel. I think the blue can was around 30% nitro. We've been helping a guy who has a Norvel 061 on a Skybaby. It runs pretty well on Sig 10% nitro Champion fuel. I'm sure it would run better on higher nitro, but for his purposes it is doing fine.

Of the cox fuel i picked up about 1/2 of it is in a red can and the other is in a blue can.The can aren't exactly new and some what a little rusty. but they were sealed good.I opened one up and the smell reminded me of the old fuel that came with the plastic cox planes 45 years ago.
On the advice from a friend on the east coastI ordered 2 of the big mig .061 engines from lonestar balsa today. They seem to have the best price. I have bought wood from riley many times but never thought about engines. Great people to deal with, fast replies to my questions.

Cox fuel.... The elixer of life!
If you deside that the Cox fuel is too low brow for your fancy engine I WANT IT!!!

Tom,
How did you make out with your norvel engines?
I picked one up a couple of weeks ago and have yet to light it off. I have some 25% nitro 18% castor fuel and am adding castor to it to bring it up to approx. 22% oil. I put some castor in the engine to soak overnight as per instructions and flipped it over several hundred times while watching TV.

Tom I haven't been able to do any thing with the two norvels engine i bought.When the hurricanes came thru here and did so much damage to the house i had to put alot of things on the back burner.On top of that my job started requireing alot of overtime.All my spare time goes to cutting up and burning trees.I am still on a list for a new roof.Before the storms i packed all the plane kits and various engines in sealed boxs.They are still packed away.Since i have to redo the ceilings after a new roof i'll just leave them stored that way to make it easier to move them around while working on ceilings.
Let us all know how you like the norvels. It looks like it will be MAYBE march before i can get back to normal.

I think this is backwards. Red can was Cox Racing Fuel, and it was indeed 30% nitro. Blue can was the standard, and I *think* that it was 10%. Run them both and I think you'll be able to see the difference. Cox Racing fuel was somthing like $96 a gallon last time I bought any. It was very high-quality fuel. I ran it in a an ST46 a few times, and in a PA40 a few times. "Power" was not an issue! It also ran out of gas right after the square 8.

I ran my Norvel 061 on 10% nitro, 20% oil Sig Champion. Blew the pug the first moderately rich run. Got another plug. Got two runs out of it. Put on a Cox high compression head and have put a half dozen runs on it. When I get around to it, I'm going to see how one of the old GloBee heads works. It may even fit the Norvel adapter. I am impressed that the engine runs very smoothly on 10% nitro, much nicer than a TD would run.
On another forum, an experienced Norvel user blamed the fuel, said if I run Norvel fuel, I will have no trouble with Norvel glow plugs.

I love Norvel engines, but mine ate a steady diet of plugs; 2 or 3 every outing. That gets expensive. I added head shims; that helped, but with power loss. Some of these guys around here gave me some great advice: Get a custom Galbreath head ($10) and a Nelson plug ($2.75? 3.50? I forgot). I bought one; so impressive I bought 3 more. Haven't blown a plug since. I even pulled out the extra shims I had put in. I bought one spare Nelson plug and it may last me a lifetime! I think the supplier was Larry Driskill of "kitting it together" fame. larrydriskill@cox.net Check it out. I highly recommend this combination. You'll recoup your investment in no time by eliminating your replacement plug expenses! --Ray P.S. I don't get a commission for this... |

Ray,
I agree!
I lost track of the number of flights (5+min each) after 55 flights and I am still using the same head/plug combo.

Yeah, I swap mine around to whichever engine I'm using at the time, Black Widows included (I have, lessee, 8 engines I think, .049s and .061s). I'm running 25% fuel with added castor, and 4 1/4" props for the RPMs. These Nelson plugs seem to be nearly indestructible. I even think the starts are more reliable. Only trouble I've had is one or two of them leaking around the threads; I had to really cinch 'em down to get them to seal. They may not come back out; on the other hand, they may not ever need to! (On Isky's advice I did use thread lubricant so I suppose they probably will turn loose OK.) I'm a happy customer.

Tom, the problem is a steel plug in an aluminum head. The aluminum can gall and just about weld the plug in place. I use Permatex "Anti-seize lubricant". It's a paste in a gray tube. Any automotive supply should have it. Good insurance when you're threading together dissimilar metals.

When using this stuff you must keep it away from the end of the plug. It could short out the element if it gets into the element.

I've always been careful about that, just from general principle; didn't know there was a good reason for it. Thanks for the information.

Not sure why folks have problems with blowing plugs. I have a Norvel .061 RC. I wired the carb W/O.
I still have all 3 head shims in. I should pull one or two out.
I have only had two problems. Both were because of me.
1. I tried to start it like my Fox. Lots of prime. It flooded it. Re-read the instructions and now no problem at all starting.
2. I went to my LHS. They are mostly into R/C cars. Anyway they had Bryon fuel. The Norvel did run worth a darn on that fuel. Went back to Wildcat fuel and it is a screamer on our Spitfire. I also tried the Bryon in my Cox Golden Bee. Not a real smooth run.
I have not found a good use for this Bryon fuel yet.

I agree with Paul as I have ran 4 different Norvel .061 big migs on Sig 10% champion and Coopers 10% control line fuel and Coopers 25% 1/2A fuel.The one engine would have over 100 flights and the other 3 are about 25 flights each.I have never had a head of any of them yet.I have read lots about glow plug contamination from using a fuel bulb and syringes with balck rubber plungers.They say it is a big no no! I have used a Dave Brown six shooter and a Carl Shoup custom syringe plunger in a 5oz sig syringe.Something is wrong if you are killing plugs every flight or 2?  |
