I just picked up a used 8ight off rcu for $120 shipped.

I plan to use my mamba max and a flightpower flightmax 5000mah 4s lipo. I'm undecided on a motor yet, and I don't have enough money for one at the moment anyway. This will be a longer project.
Here is a pic the guy sent me. I'll take before/after pictures of when I get it and clean it.
[pics didn't work]
I will fix it up for sure. I'll get new tires and hopefully the body isn't crap. Once I'm done with it, it will look almost brand new.
