When the T5 was originally built it had a different cockpit hatch and and no tiplets. It had the same hatch that the T4 had. It also had a single canard wing with flaps like the older style boats did. In fact it looked very much like the Pico boats did where the cockpit was faired into the canard wing. It was later rebuilt after Dave Villwock crashed it in TriCties. It was changed to the configuration it has now like the T6. The cockpit is shorter and more recessed with a cockpit spar and the canard wing pushed all the way forward. I would assume if they ran the T6 in Doha this year and the T5 runs stateside this year, as soon as the T5 runs in a sanctioned event it will be legal to build and run as a GT.
Thanks Ken. I have crawled all over these boats at San Diego and Tri Cities which have been my only chances to see them. I've seen the small structural differences which are mainly under the boat. Plus I crawl all over em to map them for graphics for our boats.
I've talked to Scott Liddycoat, Jimmy Shane, Jeff Bernard, Mike Allen and even Dave Villwock back in 2004 and they all had different takes on the boats. Some things were the same but obviously they all drive differently so certain things stood out differently to each.
