Hi, anyone using this nitro fuel for OS50 hyper? Is it suitable ? Heard that its comparable to Coolpower 20%.

Hi Vintcs,

I'm using wildcat 15% (for my 2 OS Hypers) for more than 3 years and i'm very pleased with it !

Hello vintcs;

Same here. I have been using Wild-Cat 15% for more than one year and I just love it!! I also have tried the Cool Power 20% and found the engine a little hot, more than the 15% wildcat, but I guess that come from having 5% more of nitro.

Wow... 15%???
I have always run 30% in all my helis. Just gives a lot more power. I couldn't imagine running 15%. I saw a guy flying a Hirobo Shuttle with .37 OS on 15% and it was a dog... We offered him some 30% and the heli came alive....

Why are you guys running 15%?

Bob

Okay, Bob, you are so right!! The OS 50 do not fell like it has power on this fuel. I will pick up some Wild-Cat 30% before the weekend and try it out. I think I will try the Cool Power 30% too!!

If your engine is running hot on 20% or even 30% you may have it too lean... When your done flying you should be able to stick your finger up into the back of the engine and it shouldnt burn you.

All you guys must earn a lot of money to be flying on 30% nitro. Over here it costs a lot more than there with you. Most of the guys i know just fly on 15% and have plenty of power.

I know if you will fly 30% that your engine will have more power and be cooled better, but some of us do not have a deep enough wallet to fund all the fuel !

Just my 2 cents !

Nothing wrong with 15%. I burned 2-3 cases on 15%. I moved up to 20% for 4 cases. I have been burning 30% since then. As it was told to me by quite a few "big" pilots, if you aren't doing tic-tocs, you don't "need" more than 20%.

Umm well.... OK... you believe that... I know better!
I swear running 15% is like plugging up your pipe up half way.

If I need to show it for fact I can shoot a vid of the difference. It's like running crap bats on an electric vs good bats. Sure it flys good but having good power when you want it is not worth the trade off. Tic Tocs or NOT!

Hi Bob,

If you would find the time to shoot a video, i would like to see it !

Do I have to shoot video of some "good" pilots flying on 15% to prove you wrong? I shouldn't have to.

The point people are making, that you seem to miss, is that 15% costs less than 30% and some people just can't afford or justify the cost if they are only doing hovering and some basic forward flight. Think of it this way Bob, it's like driving a Ferrari to work in LA. Sure the car is fast, but you are stuck in traffic most of the time so what good is a high performance sports car in traffic? A Kia will get the job done.

I agree with ClayK to an extent...

If you are hovering or sport flying... I can definetly understand using 15% to save some cash, however, if you are flying 3d, suck it up and deal with the money.. cause 30% is WAYYY better :D

Finless

10-11-2007, 12:11 PM

I dont...
The ferrari thing is a little much. More like a VW bug (15%) vs a decent 6 cyclinder car (30%) with good handling.
Sure.... Just hover.... Fine go 15% but FF with loops and basic stuff trust me... Once you try 30% you WONT want to go back.

And yes Clay lets see a video.... I aint saying it cant be done but then ask the Pro Pilot his preference! I know what the answer will be.
I have some 15% myself since I run that in plankers. I surely can show the difference and will try this weeekend time permitting (Wife's Birthday this weekend). Again it's like having your muffler 1/2 plugged up.
To put a little relation to it... It's like running a old 15C 1 gen battery vs a newer 25C. The difference is that large in my opinion.

Bottom line if I was STUCK flying 15% I would probably not fly a nitro.

Preference to the "Pro Pilot" flying "Mad 3Dz" or the "Pro Pilot" doing circuits and hovering? If the cost is $5 cheaper a gallon for 15%, do you honestly think that a "Pro Pilot" would have the illogical deduction to say that someone needs 30% for circuits and hovering when a new pilot is just starting and worried about fuel costs?

If a "Pro Pilot" made the recommendation that I should start hovering with my training gear on 30%, they don't know what they are talking about. As a point, I used 15% and 20% for basic aerobatics and the only advantage that 30% proved was the ability to get out of bad situations quicker.

My point is simply this: For hovering and basic circuits, 15% is adequate. If a pilot has a concern about cost, this can address that concern. Do you have any idea how much 30% costs over in Europe as compared to 15/20%?

Again, back to what I said originally, as I was told by a more experienced pilot "you don't need more than 20% if you aren't even doing tic-tocs". Again, it would appear if you missed what I wrote. There is a difference between need and want. There is also a difference between preference and requirement.

I did read that and STILL disagree..... Hovering yes... if your starting to do loops and such 30% all the way. I like flying big power loops and 15% doesn't cut it. So I agree with the hovering thing but not if your starting to do basic maneuvers. I like power when I want it and 15% feels like I am running a .45 engine or something. PERIOD

BTW a pro might say that as they have great collective management. So sure just like on E helis a pro can make a turd look good. I am talking about us average guys that need some power when we need it. Again if you are doing basic stuff and starting to try some 3D once you use 30% you wont want anything else.

You disagree that 30% is not a necessity for basic flight?

I guarantee you that I can go out and do loops and flips on 20%. I might like 30% because of the power but by disagreeing with my statement you are saying it's a hard requirement which it's not.

You also didn't answer my question about knowing the cost difference of fuel in Europe. But, to save you the time, the cost delta is quite a bit. For someone simply hovering and doing figure 8's, flying 30% is overkill. The analogy would be putting in 93 octane fuel in your Honda to go out and putter in stop and go traffic. Personally, I'd rather use it in situations where I'm not just going to the store and back or sitting in stop and go traffic. It's a waste and costs more when there is no benefit seen from using the 93 octane in those situations.

I'm not disagreeing with you that 30% is a better fuel choice, where I disagree with you is you saying that it's a necessity for basic forward flight. The key words you used in your previous posts were "preference", "want", "like". I personally didn't say anything about basic aerobatics and the requirements, I referenced a quote from another pilot and their opinion. However, since you brought it up, I think that 30% helps but it's not a necessity (there's that word again).

Can someone fly on 15-20%? The way you are making it sound is that it's 30% or nothing. Azlum understood exactly what I was saying. Hovering and circuits, 15-20% is fine. 3D, 30%. (in case you didn't know, circuits do not involve loops and rolls)

Finless

10-11-2007, 02:02 PM

Well there you go taking it to extremity again and putting words in my mouth I didn't say. Did I say it was a necessity? nope...
What I am saying and will say again is once you run 30% you wont want to go back and yes this is for loops and stuff. Oh and yes it can get you out of trouble when learning loops and stuff as you have more power to get out of mess ups.

We can argue until the cows come home. And so once again I disagree. If you are at a point of learning basic loops and stuff like that you should be going to 30%. Is it a necessity? no.... but certainly a preference!

I'll say it again... If I had to run 15% I would stop flying nitro's.

As for the cost in Europe.... I honestly don't care. This hobby is expensive and you gotta pay to play. If you can only afford 15% well then be happy with that if you can. I would save some euro's and get 30% myself or stick with flying electrics. Why fly a DOG when you know there is something better?

I agree with Finless, It's also like learning to fly on a trainer...they suck! Once you buy a nice plank or heli the learning curve goes way up. You get what you pay for! If you can afford a nitro heli you can afford the fuel. Why would I buy a sports car and put a v6 in it? Hey man check out my Corvette! It really gets great mileage with that briggs and stratton I droped in there.....:smokin:

Bob & ClayK;
Today I went to my local hobby shop and pick up a gallon of Cool Power 30% nitro and ran two tanks through my 600 at lunch time. I must say, " WOW ". The OS 50 have tons of power now!!! Like Bob said, when you fly using 30% you don't want to go back to 15%. I would say to newbe flyer, start with 15% than go to 20% nitro and than jump to 30%. In my plank flying, I use 30 to 35% nitro and love it. The cost of going to 30% is a big jump, but look at what you have sitting on your worktable right now!! The total cost of my 600N as it sit on my worktable is over $1,500.00. That is with everything!! I am not knocking people for flying using 15%, bit just think how much fun you will have to see your 600N come alive!!!
I am not in to hard 3D flying, but I love the new speed and power I now have!!
The bottom line is fly with what fuel will make you happy, but Bob is right, when you fly a 600N with 30% in the tank, you will be very happy with the new power!!!!
Again, just my two cents!!!

Well I flew 20% for years but once I switched to 30% I never looked back. Actually I grabbed the wrong fuel last time I was out and was wondering WTF was up. Then Clay was like "Dude why are you running 20%?"

ClayK

10-11-2007, 03:41 PM

That's your opinion Bob and you are entitled to it. We can agree to disagree. ;)

Oh and Helio, my V6 puts out 270hp. That's plenty of sports car, I don't know how you could think that a V6 is not even in the sports car class. I guess BMW and other 6 cylinder sports cars aren't really sports cars :dontknow I suppose Germany has it all wrong? :thumbup:

Nice disucussion ;)

Well, i understand all your points, but right now i'm learning tictoc's, i do loops, stall turns, inverted hoovering, flips and so on, as for now i'm pleased with 15%.

I won't argue with the fact that when i would be using 30% my engine would come more alive, but to me it's still the cost of flying ! So far i'm happy, that's all that counts to me !

But, you guys made me curious, so i'll be trying some 30% soon and see what the difference will be ! I'll let you know !

Oh yeah, and the fuel cost in Belgium : 15% is about 26$ and 30% around 42$, so to me that's a big difference.

Dirk
