Just for my friend Rich hear is a link to the old thread on the drag flatty. Since that site is all but dead due to Dan loosing interest in RC boats I will answer any questions on my forum.
http://rcdragboats.yuku.com/topic/544/BBY-s-New-flat-bottom-Runner-Bottom.

From a local FE Dude
Randy, I ordered two different jet drive units made by KMB one is 28mm and the other is 33mm they also sell a 40mm unit but I thought that would be to big for this hull. I like your idea about a front hatch lets work on that. Here is a link to the jet drives I ordered : http://www.jet-drive.de/ .


Thanks for the link Rich I took some pictures of your hull in the mold . You wanting to build one of the Runner Bottoms will makes me want to finish mine So I can race you at Heather Farms. We need to get rid of the Bouies so we can really have fun.

I just figured out how to cut the second hatch.

This is what I came up with. It will work great I think.

One of the things that has stopped me was the side seams on my boat were not sealed and had a mess of slurry all over the seam. I could not get to it to fix it until I cut the new hatch. Now that I was able to get in there and grind the old slurry off I was able to tape the out side and fiberglass tape the inside to make it water tight. I have to let the epoxy dry today and will not be able to do more until tomorrow. then I will install the hatch braces.

I think it would be cool to have drag boats offered as a class at saw trials, the traps are already there!

Ya Me too I am glad I built this mold, Some day I want to build a bigger one like in the 35 inch range. But for now this 22 inch boat will have to do

I installed the Jet drive housing yesterday it took 2 hours to install.

This is the motor I am thinking about running it might be a little hot I will start off with a 4600kv or 5700kv. I need to cut the epoxy on the bottom of the motor mount to make it fit correctly

I have ran the boats threw the traps my little Hydro it did 55MPH not bad for a 1/10 scale 24 inches long. the 1/6 scale are a litle too big at 44 inches. They (NAMBA) will let you run them we just have to put them in a class that works for the hull and power volt rating. I do not know much about IMPBA rules.
