RE: my 7.5 dpi tunnel
It's not the original color as the one in their ads looked to be darker. I used to race against another red one and they do look good that way.
My major problem was getting enough fuel under the cowl as most standard tanks don't fit. I tried several setups including two 6 ouncers inline but ended up by getting a Grim Racer 13 oz. fuel cell and that fit great. It's too bad that he isn't in the business any more since he went to work for Aquacraft.
