I believe most of the rust will be caused by the humid climate we have in Brisbane. We are in Autumn, 20 degrees at 9pm with 73% humidity.
Storing engines in a humid environment certainly doesn't help.
I should have mentioned that if i do wash the engine out with fuel post a glow plug failure for example (which is extremely rare when an engine is tuned properly, running on good fresh fuel with the correct rating plug installed for the climate and nitro %) I let the engine air dry leaving the oil residue behind and then use a little bit of the Novarossi special oil for engine parts to rebuild it.
I maintain that ARO isn't really needed 99% of the time if the engine is stored correctly and actually there is an argument to support leaving the engine alone if all is running well - the engine will give higher performance.
The use of ARO is a personal thing I guess but for me storing the engine indoors (not in a damp shed!) in a sandwich bag with the silica gel has been fine for many years and it has been a very long time since I suffered an engine failure of any description. Jeez now I've just hexed myself
