Thoughts on a 1/10th Classic Hydros Blaster

[Steven Vaccaro]

I asked Doug about maybe making a Blaster kit, here is a link
http://www.offshoreelectrics.com/pro...rod=ch-Blaster

but in a 1/10th size.

He said it would be about 33.5 with width of about 16.75.

His concerns were how it would fit into rules and such. Im not very up on those things, so Im asking you guys what you think?

That is not the right size for 1/10th scale tho. Too small.

[JimClark]

using the numbers off the current master roster list the length would be 34.2 inches long and 16 or 16.2 wide depending on the year. The 1982 is the slightly wider hull.

Does 1/10th scale allow a full 1" +/- in length? If I remember, there was one club that does not? Mike

[JimClark]

ERCU is Dimensional tolerance of plus or minus 10 percent is allowed except overall length shall be plus or minus one inch (1”).

CT is Tolerances on the length and width of club hulls will be LENGTH PLUS OR MINUS 1 INCH and WIDTH PLUS OR MINUS 1-1/4 INCHES

And Namba
The true scale dimensions of any Scale Unlimited Hydroplane will be derived from
the unlimited dimensions listed on the Scale Unlimited Hydroplane Master Hull
Roster. Boats will measure within the following tolerances of the true scale size,
excluding appendages.
a. Overall Length ……………………………... ± 1 inch
b. Beam…………………………………….……± 10%
c. Maximum Depth……………………………...± 10%
d. Afterplane Length (three point design)….……± 10%
e. Tunnel Width…………………………………± 10%

Hi Guys
Sorry for confusing things on dimensions. I was thinking when talking with Steven about saying 33.5 working within the 10th tolerances and also trying to get the length just under to accept LSSH as well (if I'm right on that rule of 34" or under), so it could be exact to 34,2 and it may be too big for LSSH anyway.

Make it just under 34". A small 1/10th is NOT too big for LSSH if the weight is kept down, I'm planning on running one next season. Just make the sponsons symmetrical with reinforcements on both for turn fin mounts.

Sounds good Brian, thanks!

The 82 Atlas has a different hull design than the Blue Blaster too. The 82 boat was built with a spar and deeper pickle forks instead of a full deck in the front. I assume the design was an upgrade so the new boat would trap less air in front since Bill Muncey was killed in a blowover accident in the Blue Blaster in 81.

What the hull would be is essentially what the picture is showing the bottom of the 12th scale hull. (the decks have not been trimmed in this pic so it looks wider).It brings up more of what my intent was when Steven started the thread. This bottom is a Finlay signature design with the sump in the middle and and side tunnels using his reverse curve where air is forced more to the afterplane. I seems to work well with the 12th hull. This is really what I wanted to find out if this bottom would pass legally in strict 10th rules, and what are the rules for hull bottoms? Whatever is said may determine how Steven would like to market this as. My thought is I wanted to make a larger version of it anyway for more battery etc space.ch-blaster_unfinished_bottom.JPG

Unfortunately, the belly pan would make illegal. You're only allowed a 2.5" wide 4" long belly pan.

Thanks for the info! Actually the belly pan alteration or elimination is a pretty easy change. It does not hang down much anyway, and probably would not affect much.

[JimClark]

Definately have my attention Doug I might just be on the list for one of these

[nichismo]

Despite my subconscious reminding me of the 1/10 scale extreme kit Mike sells, id definitely would snag one of these as soon as they were available without a 2nd thought :)

[leonard feeback]

Those are not the correct type sponsons either. The Blue Blaster's sponsons were straight from the bottom of the hull to the running surface of the sponson, not relieved as in the picture.
