Have you PM'd grays garage? His last post is still 04-07-2015 08:49 PM.
This is why I am patiently awaiting his response (and answering questions in the meantime) . To find out what size water chanal he has to find out what scale I can send ,to not my results. And why is the truck does not fit in the wind tunnels(perma link#53)
In permalink 29 He asks for 1/18-1/10 scale in( as these are the two most common Scale Models available from suppliers) permalink 32 Freebeard suggested 1/3 or 1/5( I like this idea closer to life test,closer to life results) in the videos it appears his water channel is approximately 4 foot by 4 foot and may handle a 1:5th would know if his equipment can handle your suggestion.
Again I patiently await an answer

posted on his YouTube channel, I've posted here,and I've PMed. him. I have not been able to find an email/ or mailing address on his website. just checked still no contact information Help

About Me - Graham Feltham - at Gray's Garage

I engaged in this lengthy conversation as a final attempt to get ahold of him. As stated in permalink #29 hes not on hear vary often. So my patience is necessary he has only posted 8times in the last year,2 of those are on this thred once in January and as you said in April. I'm a patient person. Give him time to respond. If I do not hear back from him.I will have to find other company to hire that has the appropriate air or water test equipment and I'LL call the 3D print shop in Butte Mt about a 1:10th -1:3 scale print. The reason for me trying this route is he specifically asks on his YouTube channel ,see video link in permalink #41, anybody's got anything like this they would like to have tested send him a model. This started out with. 1 question will a 1/43 scale model work in your water Channel? And thank you freebeard and Arrowhead both have very well answer the question for me. No it will not so now I have question number 2 what scale do I need to find. Seeing as this body style of Dodge pickup only has one size model currently commercially available . That I've been able to find so far and that is a 1/43 scale ,however ,that won't work, as per permalink #32 and 36
