There definitely is a lot of oil splatter coming from the pipe, the whole right side of the fuselage was completely coated in oil after the first tank and i had to mop it up with a rag. As for my fuel mixture, I'm just using the fuel my local hobby shop recommended i use (which i don't have with me at the moment but i think its Glo-Max R/C 5% or something?). And i will definitely put that support block inside my fuselage for my nose wheel steering as it only turns well one way, because of the slop in the cable.
