Most 7.5 boats are around 34-36" and 1/4 scale size are around 45-48" or so. Give or take an inch or two.

Woodstuff racing also carries the larger gas tunnels. If you can find the plans for JD's 47" WOF Solution, build yourself one. I saw the new Zipp Kit's tunnel at the Toledo hobby show couple weeks back. It is a nice tunnel for the price. One kit came home with me.. Plan on doing a build tread on the kit build in a week or so. Other projects are first..

FYI: I had a 50" Predator X the first year out. Boat wanted to turn in lane 25, on a good pass! There are better boats out there.. My suggestion would be to stay away from the boat. When I called them to order the boat, I asked for instructions for mounting the outboard.. "Why outboard? We run only inboards." [:@]

ob nut,
Is the WOF Solution that good? I have these plans. I could not find any info on it. I was'nt sure if it was a good one or not.(I'm a newbie with boating) I have an 11cc that has never been run, do you think this would be a good combo?

I am going to be watching for your build thread, I would love to see that. What are you going to use to power it?

Roger

I've built two of the 47" solutions. Power used were 11cc and 13cc motors. Boat handled the powerplants with ease. Few suggestions for gas usage are: A: beef up the transom B: Widen the transom. I hope to make one for gas at some point.

As for the ZippKit Illusion tunnel, that will have a modified G260 motor, Lawless CuttThroat lower, Quickdraw Hot Pipe.

Do you have any pics or links to this? I would like to see one completed. I have no time for this project right now but it never hurts to look ahead

Pics can be seen [link=http://home.earthlink.net/~ob_nut/id6.html]here[/link].. The yellow one was never ran, it was sold shortly after the build completed. The red one is still sitting downstairs.
