Exactly right fuel. But i would rather have it in a different order (if the highest content is placed first as it should be.
Methyl alcohol (methanol)
Lubricant (Oil) - is not only use to lube but also to get better compression and cooling - and shall not be burned at all when exiting the motor.
Nitro is normally the smallest amount of the 3 in an old engine like the Webra 6,5.
COMPETITION might indicate that there is slightly less oil than needed to the old motor but if you can find some ricin/castor and add a little it will be fine. Ricin could probably be found in a pharmacy - you will only need a little just for the fuel you are using at the moment - not for the gallon.
Cant you get any servos? Borrow from another plane/friends anything from 20 grams and up will do fine.
