Speed lover,

It is all about you and how you drive. Some ppl just flat out love the .28 engine and won't budge cause bigger is better ;-). I have a .21 VZB V-Spec here in the states (Run mostly on NON-SUPERCROSS STYLE TRACK) and it is fine. PLenty of power for my type of driving style and I do just fine against the .28.

As far as the changes you mentioned in one of your post is all preference. Squeek carbon fiber upgrades make the truck lighter which is a nice thing for sure. The fuel tank changes to a mugen tank have been said to fix the engine being to lean. The fuel tank posts I changed out as they broke to easily. Fabricated some out of Delrin. Also changed out the radio and battery try to the Hyper 8.5 tray. Again most of these mods are personel preference. And its most driver.

Good luck with whatever you decide. I am sure it will be fun and that is the bottom line.
