RE: New HD Baja 5 parts by HPI
Hard to say really. I've not seen the upper front/rear decks listed at US stockists yet and converting £ -> $ won't give a true indication due to the weak £. But for me in the UK they work out cheaper then Turtles parts.
Keep in mind untreated 7075 aerospace grade aluminium is twice the strength of the 'billet' 6061 most of our favorite manufacturers like to use. Treated 7075-T6 is about 4X stronger.
