I skipped from Combat Speeder 0.4 up to 1.0 because, in my opinion, this is by far the best looking Combat Speeder I have ever built. I think it might be because I didn't go crazy with the greebs like I did in 0.4
The speed stat is so good because of how lightweight it is and because of the powerful boosters in the back, however the defense capabilities had to be hindered in order to decrease the weight.
The control is worse than Combat Speeder 0.4's, however the reasons why are very similar:
-Incredibly long Length
-No side Booster for Stability
Plus, 1.0's super booster is so powerful that it makes steering at any speed almost impossible.
The railings are for carrying cargo.
Please pardon the blurry pictures; my camera isn't very good with close-ups.
