F1 hulls are not that popular in the FE world.
This is because these hull design has a tendency to become airborne above a certain speed. You can adjust the COG forward to counter act this, but this affects handling.
I have a Tenshock F1, which is a 700 MM hull. I have upgraded the cooling system, power system, and put in a battery sled. I have not put it on the GPS yet, but my guess is I go about 45 MPH where I run into these problems where it wants to take flight. It does handle great.
If I could start over, I would have gotten a slightly larger hull with a similar (but nicer) 45 degree drive system, the TFL Caldwell F1
