stench of hydrocarbon
Yeah that smell you get in the front is not pleasant. I think the 2C is worse than the 2A presumably since it has a bigger engine. After a couple of sorties that smell is not pleasant in the front particularly if you're already starting to feel a bit off, though I find it is barely noticeable in the back but that may just be down to concentration.
I'd like to try an Extra 300 but £410 ph is a lot! The 200 looks like the better priced option at £260.
