I recently bought a gallon of CY 30% heli by mistake - in a hurry. I have been using Rotor Rage for several years. I ran it anyway and noticed that the oil package ain't what it used to be. In fact I could not tell any difference at all except smell. Is this the only difference left now that they are the same company ? As far as I could tell they have the same oil package. They have the same nitro. Is keeping the CY name just marketing ?

I used to run cp 30% but now can't get it. I switched rotor rage 30% and I defiantly see a power difference. The rr 30% rocks...

The RotorRage definitely has a good lubrication package, especially after-run protection. It gets hot and really humid here and I'm not having to replace bearings as often.
Other fuels may be better now as well. I haven't tried anything else after using the Byron's.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Yes, they are the same company:

No, there is no difference between them except for the smell

Nitro

I have to disagree...
Although,they come from the same place,they do have a performance difference.
I have tried Rotor Rage for years and could not obtain any Rotor Rage at one time and settled for a gallon of CY Wildcat,I have flown for 12 years now mostly on the deck 3d smack.
When I switched to the CY Wildcat the power loss was significant,i would really have to watch/time my collective management more closely.
Also,they were both 30% nitro,just my 2 cents and hands on experience...

+1 above and well said. They do perform different I can tell especially when unloading. The head the recovery is way faster! It's a little more expensive but worth it I ran cool power for 11 years I don't like trying new things even at McDonald's I get same thing every time I'm glad I got forced into rotor rage. My question who has ran VP FUEL?

In its original iteration sold by Wildcat, I believe the oil package in Curtis's blend had a bit higher viscosity that the traditional thin oil fuels such as CP30%.

The original CY 30% heli had a very thick oil package. I have burned many cases of it. What I liked about the RR was the thin oil. CP 30% gunks up my engines. Neither RR nor CY leave any deposits in my engines. I am not asking for opinions of the original CY 30%. I want to know what is going on now. Are we basically down to two fuel choices - CP 30% OR RR/CY 30%?

Is the Byron's fuel using Klotz Heliglo ?

Hey Bill, have you used this oil ?

what about VP powermaster? I've never flown it. How is the oil package in it?

I'm just getting back in to nitro after a 10 year break. Back in '06-07 my LHS had a wide variety. Now all they have in stock for my old OS 91 is the powermaster in 30%. They supposedly have an order in for CY30% but no ETA and they've been waiting for 3 weeks already

if it ain't broke, break it.

I run VP Powermaster 30% and I like it. Runs good, doesn't rust bearings, and doesn't stain or gunk up my engines.

It's 23% oil, and it's a thinner grade oil.

If VP runs like the Powermaster used to before VP acquired the branding, it's excellent.

Yes I used to run the Powermaster before it went away. Sold in 5 gallon cases. It was very good. Have not seen any in a long time.

The density of nitro is 1.14 g / cm cubed. The density of methanol is 0.79 g / cm cubed. The only way I can see that two 30% fuels could have noticeable power differences is how the 30% is calculated - by volume or weight.

I've been using Powermaster since before VP bought them. I never noticed a difference in performance, other than the color became a little more of a pale blue.

If fuel were just nitro and methanol, then 30% by weight nitro is only 23% by volume. Leaves a lot of room for MARKETING.

In my LHS, CY 30% is $28.95 and RR 30% is $32.95 ???

Well

Nitro is 1.14 g/cm^3
Methanol is 0.79 g/cm^3
Castor Oil is 0.96 g/cm^3

So when a fuel is 30% nitro what does this really mean ? When I tried a case of Powermaster 20% long ago from CY 30%, I noticed a big power drop as would be expected. How does/did Powermaster calculate % nitro ?

What we really want is obviously nitro % by volume.

For anyone who has not fallen asleep:

21% castor oil, 30% nitro, 49% methanol by WEIGHT is equivalent to

20% castor oil, 24% nitro, 56% methanol by VOLUME.

So there could be a difference in power if fuel is marketed by weight or volume nitro.

I fell asleep about 5 posts ago.....

Just kidding !!

Been there, done that and old enough to know better.....

I fell asleep just calculating this and woke up in a pile of drool.
