I just completed an aluminum conversion on my old HPI PRO 3. Now I have to put aside money for a PRO 5, which I've been anticipating for years now. I hope its something radical in design. The current designs are to similar across all current touring cars. I haven't purchased a new TC because of this reason. I feel like it wouldn't matter what brand I purchase when the design and build is pretty much the same. So glad to know the new one is coming. Really looking forward to something different.
