I too would like to try some ethanol free gas sometime if I can get it locally ,and does not have too high an octane rating.

Setup is everything, All my heli's can fly far better than I can pilot them

""Hey Gearhead what kind of gasser you fly??""

I don't yet (yet),,, ant that great for you,,

but since you asked, I got to tell you,, right !!,,>> why I know Mod'ed Engines,,

at one time I used-to port many many many Small Gasser Engines for RC Gasser Boats, I did many many types and brands,, Saws, Weeds, Blowers, Zenoah, Echo, Homelite Tanaka and others that I don't even remember their names

in fact,, (yes Fact),, I even Ported a few Professionally for one summer and those Engine all went to Boat Racers down south,, all this was before Midwest Zenoah and BH Handson !!!!!!
then one day in the Mags I see BH Hanson and Midwast Zenoah, and said "well I'm not advertising" and stopped

my Boats,, haa, my Boats were (3D Brand) Boats, my Ruff Tuff Deep V was most likely 1 of the top 2 fastest V Hulls made back then, 3D Brand customers set many Records with their 3D Glow Boats,,
my gasser did about 43 and I was happy with it because it was super Reliable with it's Mod'ed G23 and $150 Steel Pipe

the Man> "Tomas Daniels" (Owner/Founder of the 3D Brand Boats in Port Horon Mi) became a good friend, he was one of the Directors for Straight Line Speed Trials back then,, Tom wanted me to send my Boat to him for the very first "Officially" recognized Gasser Boat Speed Trials,,
but I decline because I felt it was not fast enough,, but 2 weeks later when I called Tom after the Trials i was told the Fastest Gasser RC Boat "Officially on Record" was only 24 or 25 MPH, we had a good laugh, cause the only gasser Boat to show up for that First Trials was some large scale Fishing Boat,,

BTW,, (me),, I was out there Modifying G23 Piston (this included Side-Porting the Pistons) before anyone else was doing it Professionally, (yeeaa), how do I know, because later on I was buying G23 Pistons and Parts from Midwest Zenoah and others that Ported Professionally and THEY were not offering Modified Pistons

sorry Midwest & BH, but yes yes yes yes, I was out there modifying my G23 Pistons before you were doing it Professionally !!!,,, but no big deal you are the guys that stuck with it, good for you !!!

BTW turboomni,, did you know ??,, I did>,, (back then) the Red Max Engine was a G23 or G2D,, yet the Rad Max did have a different Piston than the Zenoah Engine,,, yeeaa baby isn't that great,, the Pins on the Red Max Piston that hold the Rings were farther-apart than on the Zenoah Piston,, ant that great !! this allowed me to Widen the Exhaust Port more with the Red Max Piston than the Zenoah Piston would allow,,, flipping fantastic man !!!

so turboomni, I guess as YOU yourself put things, you can say that I was one of the very first on the Cutting Edge of Modified Piston Technology for Engines like yours

ant that fantastic man !!!

Well that's great Gearhead. I know that Hanson and Toxic and maybe Wally for all I know modify engines for boats as you did . I know nothing about boats but would like to ask is there any difference in the way you modify a engine for a heli compared to a boat? I know that Zenoah powered boats run a much higher rpm than a 90 sized gasser heli and the fact that boat engines can become unloaded at times due to cavitation of the prop or completely out of the water can make the rpms skyrocket I would think at least momentarily. On the other hand a heli is loaded at a lower rpm than a boat and programed with a with either a curve or governor to pull back throttle when the main blades are close to 0 pitch or the gov see's that rpms are out of range and correct it. When pitch is added like full collective it must grunt out alot of torque to maintain headspeed. I would guess a heli would be more torque oriented because it is loaded. with all the gears and tail, mainblades and pitch all the while trying to maintain the same headspeed or rpm.. A boat would be more hp [high rpm oriented] to spin it's small prop fast. What are the differences in modification of a Zenoah engine between a boat motor which I would assume is high rpm HP and a loaded heli engine at a lower rpm which is more torque oriented? Or am I wrong here? I would also guess a heli motor because of it's load would have to run richer than a high rpm boat with less load and the porting would have to be different between the 2 types of motors for best power at it's target rpm area. I know the major engine modifiers would not be specific in their trade secrets but since you don't do this for a living anymore can you fill us all in the modification differences between Zenoah boat engines and heli engines within your experience?
Thanks

If anyone wants to know how to get water out of gas I copied and pasted this from another site.

I don't use the "clear tube" method. I just bought a large 10 gallon plastic tank that is translucent white so that I can see the gas and water levels.

Enjoy.

if any one is interested i know how to remove the ethanol from gasoline. its veary simple.
here is how to do it.

get a 5 gallon gas can, put 1 gallon of water in it take a drill and drill a hole 1 inch above the water and put a petcock in. then empty the water out. next put a site tube "a clear hose from the bottom of the can to the top of the can on the out side tapping into the can at each end. and your done.

all you have to do now is put 1/2 gallon of water in the gas can (you shluld mark water hight on your sight tube) and fill the rest of the can with gas. wait 24 hours or untill watter level has returned to or above the mark on your site tube. (should be above your mark) and then open your petcock and drain the non-ethanol fuel out from the can into your bike or another can. (be sure the water level is not as high as your petcock).

how this works:
water and gasoline DONT mix.
water and ethanol DO mix. in fact ethanol soaks up water like a spunge.
water is heaver than gas, ethanol soaks up water becoming heaver than gas and they bolth sink to the bottom in a clear liquid. gasoling stays floting on the top ethanol free.

That is GREAT INFO, however, some of the components of the gasoline mixture that is not just ethanol will also be removed with the "washing out" method of removing ethanol. It would be much better to find ethanol free gasoline... check the marathon stores as most have gasoline with stp additives and no ethanol.

I am not totally sure what components of the fuel will be removed, but I was told washing gasoline to remove ethanol was just not a good idea as the properties of the fuel would change and then you dont really know what you have left for sure.... you will at the very least have 10% less fuel than what you started with because the ethanol is now removed...

Lol Gearhead, I'm sorry I gave you a headache. I am far from the cutting edge believe me.
Guys on the cutting edge are using SEF!!

Great info from fuzz and indycustombikes.
Has anyone done this and tried it in their gassers?

So what do you do with the left over water-ethanol mixture? Serve it on the rocks with cranberry juice :-) .

I'll stick with the SEF, little easier. And it is specially formulated for small engines.

I have a large piece of property that I have been slowly clearing of underbrush and restoring to open range for the last couple of years.

The brush is pushed into large piles and I use a mixture of 95% Diesel and 5% gasoline mixed well to get the fire started. This is actually quite safe and burns slowly and predictably. Without the 5% gasoline you can't get the diesel to ignite.

I usually throw the water ethanol mixture and any other flammable/enviornmental hazzards that burn like used paint thinner, acetone, etc. into the fire in very small quantities. I usually put the stuff in an old Folgers plastic coffee container with the lid on it and toss it in from a distance.

Various chemicals give various "boom" results. The key is to do small amounts and stay back.

I was interested in using Sparx Engine Fuel ie" SEF in my 9 to 1 compression 455 Cutlass. Would this work ok??

I have had my arm hair and eyebrows singed at least once.

The energy in gasoline is amazing. It makes a lousy and dangerous accelrant since it basicly just goes "woof". Few people even have a clue of the destructive power that lurks in the gas tank of their car.

Diesel on the other hand is one of the safest fuels I can think of. You have to really try to get the stuff to burn.

I developed the diesel/gas mixture years ago since I always wait until there has been a heavy rainstorm for safety before I burn. The brush is usually wet when I start the fire. I use about 2 gallons of mix dispersed in a couple of places at the base of a large (20 foot diameter X 10 foot high) pile. After you mix it and throw it on the gas rises to the top of the diesel that has soaked in. You esentially light the gas and as it burns it vaporizes the diesel (like a candle wick in wax) and allows the diesel to take off. This gets even a sopping wet pile burning very quickly.

If anyone tries this please remember the 95% diesel to 5% gasoline ratio and practice on a small scale first.
