I used to have the original 8ight. Now I have an 808. The 8ight is amazing how you can tell it what to do and it just does it. The 808 does the exact same thing, except it feels way easier to do it, I feel way more in control. It lands on all 4 wheels so often. The only time it ends up on its lid is if I lawn dart or screw up my throttle/break while in the air. It's so stable.
I had a lot of issues with the Losi durability. The plastics and whatnot. The 808 is unbelievably strong.
They've extremely similar cars. The 808 is basically the luxury edition. I've never had to order parts. I bought a used roller off of someone for spares. I've never used the parts from it. It just accompanies me to the track and sits there.
