 Well I did say I'd have another. Took the Irvine 40 to the club today, and with the aid of one of the trainers, got 3 10 minutes flights out of it. Brilliant.. But what a mess, when it came back... unburnt oil everywhere. I appreciate, that oil is required for lubrication, but is it normal, to be covered in the stuff. Are there different fuels, with different oil contents, and I just happened to buy the messiest ??

 I find Lithiium based fuel is very clean - no gunge at all  On a more serious note, perhaps you are running it a tad too rich ? Of course synthetic fuels are less messy, and will not cake up and go black like the old castor based ones. Different oil types and percentages yes - but stick to the minimum percentage of oil as recommended by the manufacturer of that engine.

do you have an example of a manufacturer.. i'm willing to give anything a try, if it saves mucking up the model
|
|
what engine is it
|
|
Its an Irvine 53

Regular 18% oil content then. The carbys on these things do have a tendency to chuck out raw fuel all over the place. The recommended fuel is this ( contains KLOTZ oil) Should run fine on anything in this list with at least 5% nitro.

 Hi Keaton, We use Pro-synth 10% as a standard "all round" club fuel.

 You will always get a messy model with a glow engine & it is better to run rich than lean, which can ruin your engine-you may be able to fit an exhaust deflector tube to minimise the mess, but you will always get some oil mist on your model-invest in some rags!!!.

Hi All, I seem to re-call Brian Winch making mention of air filters as used by the car fraternity... anyone tried it ??
|
|
 If the engine is quite new it will chuck out some muck. Try synthetic fuel, Irvine Contest 10, or I now use Coolpower 10% in my Irvine 53 and it's not too bad. I also use Mr Muscle Orange floor wipes to clean up and it removes the lot!

Been recommended Bekra 10 today, seems to be the norm at our club, so might give this whirl. Aparently, it has no Castor, and everyone at the club seems to think, castor is the culpret. Any thoughts ?

 Should be fine Keat. You can always get a muffler deflector to steer the oil away from the side of the model a bit (grey rubbery things sold in model shops with a 45 degree bend in them). I use Coolpower 10% like Shaun above and find it great stuff but not the cheapest. I used to use a castor based fuel and can't say I had more oil left on the model but my engines all took on a brown coating and smelt more indoors. Nowadays, they all still look brand new and last, plus, I can get away with murder with them indoors...!
