i saw this Sponson mod thread a week ago and it put me off buying her, i wonder why the stock hull has it flat; most odd, because all the cats i've seen are as per your excellent mod.
in addition, the bloke from AStec told me, that there is something wrong with her hull that limits her top speed, i think she needs reinforcing inside, this is even odder, because this guy was trying to sell her to me

but you've strengethened yours inside, so she'll probably be ok., this is the one us Brits call the HOR APPARITION, she's quite popular, she's the same hull as the VENOM ( i think)

BACKEMF

They are flat because it is a H&M clone. The original had flat isharper sponsons.

Adding what Rull did, makes it more stable in the rough.

I also think since the drives are lower that prop changes will be more noticeable.

MalcolmX

i wonder why they made this cat a single screw, whilst the other chinese versions are all twin screws, cheaper i suppose, it'll be interesting to see how well this cat goes with all these great mods.

Rull

It makes more stable at rough and more stable at speed even on calm water

what size is the triangular cross- section on the Sponson, so i can look for it this weekend.

thanks

Rull

Have you seen the attachment in the post#7 of the thread? Or I don`t understand what do you mean exactly.

sorry i didn't see it, that's great thanks

it's quite large too, i might have trouble finding that size

BACKEMF

I need to get someone to cut it on a table saw or a millwork place.

Look for airplane trailing edges. One size is 6mm x 30mm high triangle, it should be ok. At least this is what I use for ridepads...

Were are you getting your stingers from. They look really nice.

How much would you charge for two more.

Rull

Individual work in not cheap.
For cheap stingers try to find something here

Are you gonna sand the sponsons after you've sprayed them ?

Rull

I know that a bit sanding give additional few km/h. So I`ll try to do it and check

Gerwin Brommer

Putting all the effort in blueprinting the bottom and improving the edges, and then making the edges round by spraying them.
Such a shame.
IF (!!) you spray a hulls bottom, always spray with the nose pointing down.
So the boat is in a vertical position.

Rull

ok
you are talking about angle sharping. Tell me what difference will between angles with 0.5 and 0.1 mm radius in my hull?
I understand that 0.1 is better than 0.5. But how much?

Gerwin Brommer

0.1 vs 0.5 is a 500% improvement
All little bits help.
I really like your build, don't get me wrong.
