Thanks, Tom. Good thoughts here. They have a very specialized environment and set of conditions there and they designed a boat to fit those conditions and...
I've been working on a new fuselage for better aerodynamics. I based the shape on wind tunnel testing done earlier. The fuselage is wood stringers and plywood...
The fuselage is a straight taper. I made it this way so I don't have any problems bending the ply wood over the bulkhead shapes. I have the patterns in the...
I've posted the latest pictures of the fuselage progress under Wingnut lll in the photos file. http://ph.groups.yahoo.com/group/wingboats/photos/view/ed8d?b=13...
... John, Sharp looking hull! Your cabinet building skills shine again. The hull looks pretty long. Are you even going to have a front runner plank? Keep...
Thanks for the update. I am ready as one of your pushers in the Am Cup in 2008. Meanwhile I am testing a new front end on my Fed 5. Stability and steering...
I forgot to mention that the boat will be about 25.5' LOA. It will have about the same foot print as Phils boat pictured in the background on the front page . ...
John Thanks for the plug. How do the Aluminum front ends look. I don't think they are strong enough. I would like to put some side gussets on them. How much...
I was there for two days of the Bend Boyz stay and although the light air capabilities of Rich's designs were just working, mine and several other Manta twins...
Frank I have it mounted . Check out the new photo. It looks great thanks!I will need to mount the wheel on the dirtboat front end and see what can be done for...
John It looks great. Stick an axel in it and see what kind of axial load it can take. Give me some gusset dimensions and I will send you a gusseted one to try...
Hi All, I just found this group today and I'm very excited about the wing concept. I also restore and build aircraft, so I like wings. I have a bunch of...
Welcome Phil , The flap stays angled pretty much all the time. The only time not to use it is to depower. WN1 was the first small sized wing I made . I felt it...
Thanks for the response! So when you are powered up and cruising what is the average angle of attack of the main wing? And what is a normal flap setting? How...
The main wing can range from 15 to to 5 degrees at speed. I usually run 20 to 30 degrees of flap .Less if its blowing hard. We have found a chain and sprocket...
John Is it possible to put the wing you sent me on the Manta Twin that I have. If so what would it take. Remenber I have a CNC Machine shop and can do...
The wings require a large platform for stability. The previous boat that it went on was about 350lbs and had a footprint of 18.5' long and 16' wide plus the...
John What about adding a front spring board and new rear axel to get the 18.8' x 16'? It would be real easy for me to make up the mounting plates for both of...
The problem I could see by extending a twin is that the wing needs to have about 30% of its area behind the rear axle. If the wing is too far forward then you...
Hi John, That video and other web site answered just about every question, thank you so much for sharing this great information! I live a a small airport (Twin...
John Thanks for the info. I was just trying to figure out how to get all of the Manta guys into wings. Frank smith smith <johhnysrocket2003@...> wrote: ...
Tom is right on. The difference between water boats and ice boats or land yachts is drag. To overcome drag takes power. Stability is always the limiting...
Frank, using a wing on a Manta Twin would be too difficult due to the weak structure of the Manta Twin and the fact that the mast struts would prevent hardly...
Mark Thanks for the imput. What kind of bikes do you have. I have an 07 GSXR-750 Mark H <landsail@...> wrote: Frank, using a wing on a Manta Twin would...
Hi Frank. I have in my crowded garage with two sea kayaks and three bicycles (mtn bikes and a 40 speed recumbent - Trek R200): 2007 Kawasaki KLR650 2004...
