Original Super Power fuel formula?

Post  wha-tah-hey on Mon Oct 10, 2016 11:02 am

A search brought up many posts about fuel for Cox engines, but I'd like to know the nitro/castor %'s of the original Super Power.
Thanks.

Thanks for the reply, Eric.
That thread is on Hobbico's fuel and, best I can tell from the posts, is 25% /20%, which may or may not be the same blend as Cox's original Super Power.

The original Cox in the red/white/yellow/orange cans, 8 oz stk #550, 16 oz stk # 551 - I don't know how/see a way to insert a pic.

Hobbico's Cox Super Power Fuel formulae:
COXP1005 25% Nitro
Contains:
25% Nitromethane
55% Methanol
10% Synthetic Oil
10% Castor Oil

COXP1010 35% Nitro
Contains:
35% Nitromethane
45% Methanol
10% Synthetic Oil
10% Castor Oil

From this I assume the old Cox was 25% nitro/20% oil, but all-castor.
I'm trying to find out if that's so.

Go to "Instruction Sheets" in the Info section in the left margin. Then go to "Other Cox Related Documents ". There are original Cox fuel formulas in there, except no reference to the name "Super Power".

Cox Super Power fuel must be a different formula - a can came with all the Cox plastic RTFs.

Thanks for the link, Eric.
My question was prompted by concern for a good quality fuel source for Cox engines.
After going thru all the info I've been led to by you guys I see Mark and Rusty, among others, are completely satisfied with Hobbico's blend. That's good enough for me! Very Happy
Thanks guys!

OUCH! That's PAINFUL to see! affraid

In Kim's thread, Rusty says " Btw, the old Cox red can is... was 30%."
So more than the 20% I was thinking.

Google images for Cox fuel. I did after reading your post trying to find out the formula you requested and actually saw a can with only red and white, and not the one that you have pictured. I have the can you have pictured at home, but I looked at it very carefully and there is NO mention of percentages on the can anywhere. But on the plus side, I myself am going to go look at getting a bottle of the NEW Hobbico fuel today as I heard that it is available locally. I'll let you know if it is the new stuff.

Obviously, I'm no expert on Cox fuels or their cans. Smile
I don't know that Cox listed % on any of their containers (suspect not).
The red/white can you saw may be the fuel Rusty referred to , while the can you have is what I had in mind and possibly lower nitro content (BTW, I've NO idea where I got the notion that it was 20% - may have just made it up Laughing ).
In any case, given the enthusiastic thumbs-up it's received, I'm completely comfortable with using the Hobbico blend if I can find it.

Sig Championship Fuel 20% Lubes, 10% Castor + 10% Synth, 25% nitro

Post  PeterJGregory on Tue Oct 11, 2016 8:18 pm

I have been running a little of the above-stated Sig fuel lately and am going to be putting in an order for a gallon of the stuff at about $23. Not sure what shipping will be on that, there may be a premium for a full gallon, so I may downshift to ordering quarts, as I have done in the past.

About two years ago I was following and involved in a thread where flyers found that the Hobbico Super Fuel wasn't using enough Castor oil and damaging some engines. I was lined up to do a destructive test with a bunch of brand new SureStart .049's when a more influential group was actually able to get Hobbico's attention and helped them change the formula to what is sold today. So, I would feel safe with the Hobbico Cox Super Fuel, except I think the Sig Championship is cheaper. Somewhere I have a collection of Sure Starts that I never used for the test, I think five.

Pete, you will definitely need to buy it in quarts to avoid a huge hazmat fee.

The new Hobbico fuel is very good stuff, or at least my Beta test quart was. I still have a few ounces and was using it in my Li'l Satan at 1/2-A Day, as seen in my video. Got a standing O for that flight, that's a first, but also a testament to the fuel. It was 25%, but when I restock, I'm going to get 35%.

I hope there is none of the old stuff on dusty hobby shop shelves, beware of that. The new stuff is all clearly labeled with the contents. The neck of the new bottle has wide vertical ribs. The neck of the old bottle has narrow horizontal ribs.

I haven't had time to read this whole thread, but have seen myself quoted. Are all questions answered to the satisfaction of the OP?

Bugging you, bugging me.... I agree. I would also like to know the original nitro content now too.

And as a side note. I did not pick up any of the Cox branded fuel today, as they do not, nor did they ever have it! Buddy at work is going to get it tomorrow now! Went out of my way to get there, then find out they don't carry it, nor have they ever heard of it. Shocker... They even told me that there is no such fuel available as Cox went out of business many years ago, new Cox engines are no more, and parts are no longer available? I guess their claim of being Canadas Largest Stocked One Stop Hobby Shop slogan doesn't fit! Or at least they need to do some learning of what is available out there. Anyways, rant over. Sorry.

Ok. I think I MAY have figured this out. So, the blue can is 'Flight Power Fuel'. Both the 'Glow Power Fuel' and 'Super Power Fuel' are also BOTH marked for 'Cars, Planes, And Boats'. With that said, in my opinion, they both may be one the same. No science, but no documentation or fuel formulas for the Super Power Fuel, yet both marked for the same applications. Now the shocker to me is that the documents provided here of the formula shows the Flight Power at 15%, and the Glow Power fuel marked as 10% which I think is low. Or does Super Power mean Race Power in which would be 30%? Wow, my brain is aching...

I'm pretty sure the two are the same formula. If you wanna love Cox stuff, then get used to being "pretty sure" about a lot of things.

While we have the posted formulas dated, without knowing the production period of the cans in question it's hard to say if there's any connection between them.
Still guessing but I'd say, with Glow Power @10%, Flight Power @ 15%, Race Power @ 30%, Super Power may well have been 20 or 25%.
Of course, it could have been 35% too.
Either sorta fits in a "name progression" ad scheme.

Tell ya what - Rusty, if you're willing to do a comparative "tach race" with the new 25% & 35%, I'll send you my pint can of Super Power. Maybe we can recover some lost Cox history about what the stuff is to pass on.

In the 70s most of the time the basic Cox fuel was the choice because of cost so it must have been the Glow Power 10%. A container of Race Power was at least 25-50% more cost and other than the cool factor just wasn't worth it for kids sport flying their planes.

From the 1985 year catalog in CEF, looks the same as flight power. Also there was a special blend for cars that had more oil in the mid 70s.
