I just recently purchased a heli with a OS .32 motor. What percentage nitro and oil should the fuel be for running this motor.

Thanks for the help

i recon 15% nitro and 20% oil will be fine....thats what i yous in my 50sxh and it works fine so it will be fine aswell in your .32......just keep away from caster oil.yous synthetic

Let me re-qualify the question.

The gentleman I got the Nexus 30 from said to use 15% nitro with 18% oil while learning to hover and basic's. Then go to higher nitro content when I begin doing manuvers.

I have a LHS that sells 15% nitro with 18% oil (80/20 synthetic/castor mix).

I have been reading in the different threads where folks are using high nitro (20% and up) contents for theirs.

Thanks again

For an O.S 32SX-H 15% nitro is plenty.

For demanding maneuvers 15% will also be fine and 18% oil is perfect.

I have been using Cool Power 15% in my 32 and it really works well.

that thing about yousing 15% for lerning and then going to a higher percent for doing 3d and stuff is not right....if you start on 15% and then go to say 20% you will have to ree tune the engine...what fuel you lern to hover on is what you lern 3d on....and enyway 15% nitro is fine so you wont have to make eny changes

Stay away from Castor.

For you the best bet is either 20 percent cool power heli or 15 percent cool power (they are all the same) and get a bottle of morgans oil and add 1.5 oz to a gallon, that will bring the oil content up to 18 percent.

Now the next question

I see that I need to stay away from castor oil. What will it do to my motor?

If it sits in the motor it gums up. Also makes nasty looking burnt gunk all over your muffler.

Most of the heli guys fly all synthetic. Also hook up your glow plug and crank the motor till it doesn't pop any more at the end of the day, that will burn all the fuel out of the engine.
