THe SLo-V was my first plane, I'm using a stock setup with the 7 cell battery upgrade.
I think if i had the choice again I'd go with a Slow Stick, it would have allowed me a lot more versatility in electronics and what not and i believe the speed mods aren't over the top for the plane to handle - which my Slo-V doesn't doesn't seem to like with it's flexible wings and it's fine by me because I usually like to take the plane as high as I can and do a bit of gliding so it's more of a plane I like to take up when i'm done battling it out with my warbird
