I've noticed this too, I make an effort now to only buy what I plan to run, initially I wanted a spare of every part for every car I had, but I found myself vacuuming up the last couple items/parts stocked and keeping them on my shelves.
I'm still at a point in my nitro career where I want to...
That's a gorgeous bit of work.
I have to ask, ever going to take it past first gear? I wouldn't blame you for keeping it pristine, it would be pretty nerve-wracking to get it to full speed with nearly irreplaceable parts...
Also, what's the fuel endurance like? That looks like a standard 75cc...
