Nice work Mike!
How did you make up the sides, what core did you use? Is it all sheeted with 2 layers of 6oz cloth?
Is the cowl molded?
Pressing a lawyer with a 2 ton bottle jack sounds good to me........... :lol: :lol: :lol:
Very kewl, I wish I had access to that kind of machinery...Nice work Mike!

Terry,
The hull sides and bulkheads are 3/16 5 ply birch ply wood. Yes it is 2 lawyers of 5.8 oz. bidirectional weave. .022" thick 10" x 4 ft sheets were made in a home made "press" using five 2 ton bottle jacks. Only the inside (boom tube side) of the sponsons have 3/16" ply on them, the rest is skinned .022" carbon over Divinicell (however you spell) blocks that were 3-D cut on a CNC machining center. The 43" long hull sides werw also CNC cut after they were skinned in the press also. The cowel mold was also CNC 3-D cut (no "plug" needed here!). In fact every aluminum part wes made by me in a CNC except the Aeromarine pretty bolt "washers", Speedmaster strut, and CMDI rudder bracket (x-tra wide 7075 aluminum rudder was made by me after bending the CMDI one). I even cut the .05" titanium turn fin on a CNC. I spent countless hours 3-D modeling the whole boat on the computer before cutting the 1st peice. The boat race ready with no fuel weighs in at 10 lbs even. Not the lightest F rigger on the planet, but not bad neither. It's bee clocked at 88mph in heat race setup and can be driven any where you want to put it on the course.

Nice job!!!
I have put both the EVO 1.0 and RS91 in it and I think the RS has alot more rpm without any loss of torque that I noticed.Superb looking boat, Im in the process of building a rigger made out of CF sheet. Yours is hands down THE best looking rigger iv seen to date, also how ya like that 91rs? Iv got one on the way for my mono.
Great work Mike , were you in Atlanta with this boat
