RE: closer to 50
Nitro you will find with the sv that the 2300 has plenty of power. Avanti27 has the sv/ammo combo, and right now he is just trying to figure out how to get it to lay down and run.
Bob the XL motor will most likely be next. I am just so close though, that I want to try and break 50 as it is before I step it up.
Dustin, I will probably go for 60, but it will probably take some changes to do so.
