RE: 21 Tunnel Talk
 

In the process of hand drawing out my tunnel hull plans, should be interesting how it turns out!:D

RE: 21 Tunnel Talk
 

Cool, Post a scan or pic with what ya come up with.
The members here are happy to help ya out with measurements etc.
I like new stuff,
Gene

RE: 21 Tunnel Talk
 

Gene, <div>I can tell you that I am going to make it a 10 inch beam by 27 inch length I that pretty good on measurements?</div>

RE: 21 Tunnel Talk
 

My Villain/VS1 is 11 1/2" and 28" long so yea thats real close,
Gene

RE: 21 Tunnel Talk
 

Alright heres my design....<div>http://i1301.photobucket.com/albums/...ps7658ede1.jpghttp://i1301.photobucket.com/albums/...psa3b0e936.jpghttp://i1301.photobucket.com/albums/...ps102be670.jpghttp://i1301.photobucket.com/albums/...ps7cd97090.jpg

RE: 21 Tunnel Talk
 

Interesting, Ya might make the tunnel sides 90 degrees to the tunnel floor.
Jerry D. is your go to guy for design specs,
Gene

RE: 21 Tunnel Talk
 

Slidebleus,<div>I did notice on most all tunnels that the sides are 90 degrees, thanks for the info i really should have taken note on that before.</div>

RE: 21 Tunnel Talk
 

No problem Dude,
Keep all the edges sharp so the water will shear off.
Good luck with your design,
Gene

Pic of VS1 for details:

RE: 21 Tunnel Talk
 

Alright here are my new plans that i drew up from scratch on my dads bobcad software..what do ya'll think?? Its 10 inches wide not sure how long i will make it..maybe 27 inches like i wanted my drawings a few posts up..input would be much appreciated thanks<div>http://i1301.photobucket.com/albums/...ps255c7264.jpg

RE: 21 Tunnel Talk
 

Another good thing your bulkheads resemble Jerry's HS Sprint, a already proven design.
Only yours would be three inches longer at 27.
Gene

Added pic:
Angle of the sponson bottom sheeting (deadrise) 12 to 14 degrees,
Stay close to the dims and you should be fine.

RE: 21 Tunnel Talk
 

I didn't mean to do that, so the size or length I mean should be shorter maybe? Like how much shorter??

RE: 21 Tunnel Talk
 

27 is fine, With the current outboards .21 tunnelhull class are 28 to 30" long.
Gene

The HS Sprint is a little short at 24" by todays standards......

RE: 21 Tunnel Talk
 

Alright thanks. Hopefully I can convince my dad to go pick up a wood bit for our CNC machine :D

RE: 21 Tunnel Talk
 

Neat project! Yes, 24" is too short for the new faster motors. I think my Vision is 29", but I would have to double check.

RE: 21 Tunnel Talk
 

So ya'll think i could put a k&amp;b 3.5 or os .21 outboard on it???

RE: 21 Tunnel Talk
 

The O.S. 21 is a better engine - it holds all the 21 tunnel class records.

But, some guys still run K&Bs. Just not the guys winning national championships.

RE: 21 Tunnel Talk
 

JD thanks for the advice, im gunna have to look for a used OS 21 because there not cheap!![&amp;:]

RE: 21 Tunnel Talk
 

Watch the online hobby stores like Towers. They go on sale from time to time. My brother picked up a new air cooled from Towers for $329 about a month before Christmas. Add a coupon and it gets cheaper. Just have to plan it right....

RE: 21 Tunnel Talk
 

Hey thanks for the advice. I will look out for it. Right now the aquacraft VS1 on amainhobbies for me at least is 133 dollars.. Tempted

RE: 21 Tunnel Talk
 

Ya might be better served goin with the TS3.
Reason is depending on the production run some VS1's had voids in the seams.
Where the transom joins the center section and sponson sheeting.
JD has a neat check if you have a suspect seam, Just run some thin CA along the seam.
If it wicks in ya got a void, If it rolls along ya dont.

Dont get me wrong Im a nut for that boat on my third right now, Just fair warning.
TS3 is purdy much plug and play just follow the instructions, Tower has sales on them all the time,
Gene

RE: 21 Tunnel Talk
 

Slideblues, I might end up getting the VS1 because of how it looks and how i believe it will perform.. The TS3 would be great to because of the readiness of it like you said. I want to hurry up and get one while the weather is good here in Cali.<div>Regards Josh</div>

RE: 21 Tunnel Talk
 

I got the TS3 from Hobby Warehouse 4-5 months ago for 74.99 + shipping (now 119.00)...lol, Then I found the VS1 for 87.99 in January at Tower Hobbies (now 159.00)....you have to have patience .......maybe they were typos...lol...anyway thats what I paid......you just missed 2new TS3s for 89.00 each on ebay

RE: 21 Tunnel Talk
 

WOW...I commented on this thread and now no activity for over a month......I dont bite.....lol

RE: 21 Tunnel Talk
 

I started the thred back in June 2011,
Kinda goes in sperts, Not much to report as of late.
Gene

Jerry came up wth a way cool design for the 7.5 class,
WOF construction shaped like a TS3 on steroids........

Added a screenshot:

RE: 21 Tunnel Talk
 

Here's photos from the back and bottom of my new boat. I'm calling it the TS 45.
