Actually the water injection was supposed to cool the motor and air so to provide a denser air fuel mixture. It really didn't and was dropped, it was advertised quite abit in the mid 80's in Hot rod mags.

I knew you had to be kidding also. I don't think I'm going to be trying any water with my fuel. We have enough moisture in the air in my part of the world. I usually don't have any problem with rust though......I don't run any nitro......and the 5% acetone that I use is rumored to help keep water out of the fuel.

Acetone ? I haven't heard of that one before. Are there any chemists around ?

A club mate who is a chemist warned me that adding acetone would probably mess up the seals in the carb , so I never tried it .

At the end of the day , it gets dark .

Never had a problem with the acetone. I can't remember where I read about using it the first time. Do a search on the subject on the net. There are several articles about it out there. I recall that several of the guys in Australia use acetone in the fuel....no nitro fuel. I can tell a difference in idle when I use it. I run 5% acetone and will continue to.

RCUniverse has a whole "fuels" forum dedicated to the people who mix their own fuel. I read about the addition of acetone there, as well as other "dubious" additions. Some of the ideas for fuel and additives presented are downright hilarious.

I know we're getting off topic here.......I haven't tried any of the other additives that were mentioned in some of those posts. Acetone is the only one that made sense to me. I can tell a difference using 5%. If I find that I need it to run "like it has nitro" I will just put some nitro in it.

Can i just ask,
Whats the advantage to running Acetone?
Would adding some unleaded to straight nitro work atall
Or am i missing something here again

But yes, Unleaded a bad idea?

In the seventies , a few of our club members used to add a couple of percent petrol to their straight fuel in the winter .

At the end of the day , it gets dark .

Any joy with the straight fuel & octane?
Did the engines run hotter?!

I never add anything extra to my fuel for cold.
The heli loves the cold.
Storing gin the cold is no problem as long as you are not getting condensation.

When you arrive at the cold field, give the heli 15-20 minutes to let all of the parts reach the same temp, then readjust the belt tension, then fly better than ever.
At the end of the day loosen the boom before putting the heli in the car.

Adjust the needle valve to make it run right just like you did in the summer. There is no magic number of clicks to adjust for the cold. To many people get caught up in the number of turns open to try to duplicate someone else’s result. There are way to many variables to try and use someone else’s needle settings other than as a .VERY, VERY rough starting point.

In my case......OS .46, Hatori Pipe, running 0%. I use the Acetone to help with idle and it just seems to make the motor run a bit smoother. I talked with a guy in Australia that was doing it, so I thought I would give it a try with my straight fuel. I think it helps. It has also been said on other forums that it helps keep water out of the fuel. I don't know if that is true or not. I run 5% acetone in my fuel. If I were running any nitro, I wouldn't even bother with the acetone.
