Fuel question
 

Hey all, just got my Hangar 9 P-51 PTS and I am planning on heading out to the field tomorrow, question, i am a long time nitro heli pilot and I was wondering have any of you or can I used 15% Heli fuel in the planes ?! I have over 6 gallons sitting around so I figured and save some doe..

I know, this sounds like a very newb question, but I figured ask just in case...

I use heli fuel even in my Revo, Savage and LST cause I found it gives me the most stable idle...

Thnaks,

It should run fine in your engine

RE: Fuel question
 

Yes as long as you check oil content est. and make sure that all matches with the engine manual

RE: Fuel question
 

Yes :D

Cool Power 15% is all that I fly in my planes, 2 and 4 stroke. You won't have any problems with your 15% fuel.

You may need to slighly re-tune the engine, but that's about it.

The 15% will be a bit more forgiving of the tuning on that engine.

I've done this w/o problems.

+1 for Cool Power 15%

Go for it!!

RE: Fuel question
 

The main difference I've seen between plane and heli fuels is that most heli fuels have only synthetic oil, while most plane fuels typically have a little bit of castor as well.

As far as running plane/heli fuel in cars, I'd suggest against it. It will work, but you won't get very good performance. I ran my nitro buggy on 15% plane fuel initially, but it ran much better on 20% car fuel. The additional nitro no doubt helped, but the big difference was the reduced oil content of the car fuel. Plane fuel smoked pretty badly in the buggy, and top speed suffered pretty badly as well.

RE: Fuel question
 

Same here, my car fuel only has 12% oil.

RE: Fuel question
 

The type of oil doesn't matter. There are airplane fuels that are all synthetic and some that are a blend. People swear by both but I like castor. The main difference will be the oil content. The plane will be a little more oily but you will do no harm.

RE: Fuel question
 

Castor is supposed to protect against a lean run, but it gums up the engine after awhile with varnish build up. Helis typically run richer than planes, so Heli fuels usually go with all synthetic in favor of less varnish build up, since lean runs should be less likely. Most plane fuels still have a little castor (2% or so) in addition to synthetic to protect against a lean run. As long as you're careful not to run lean to often or too long, the all synthetic heli fuel will be fine. Total oil content for heli and plane fuel is usually the same (17-20%). Some heli fuels may have a couple percent more than the plane version for some brands.

I used the white lightning 8% oil 30% nitro in my 1/8 scale buggys. I tried some in an old
.40 that a friend gave me that wouldn't run for more than a few seconds. I put the lightning
in it and got it to run rich. and flew that motor for about 15 flights, still had an occasional deadstick
and the motor would not run when leaned. I tore the motor down and found that the nickel plating
on the cylinder had flaked off. I don't know if the fuel and low oil content killed the motor but I
do know that that is the only fuel it would run on.
