Outerlimits SV43 build

[fweasel]

Sorted out the issue with the sloped transom. Sent the mounting bracket out to have a 4* angle machined onto the mounting surface. Came out perfect, not even a scratch. Rudder mounts up perfectly now.

Very nice Ryan!
I have my one motor to two drive shafts gear box and am designing a mount system for my baby sv43.. I’ll post some pictures some to get some feedback.

And I ran my baby raptor this weekend; Here is video.

That hull is aired out very nicely. Do you have photos of that build posted anywhere?

[Jesse J]

No pics posted anywhere.. I can summarize here if you like.

You should definitely start a thread for you build, easier to find. It's becoming a popular hull and people will want to see it. I'll probably combine both my Raptor builds into a single thread.

Good point.
Probably do same for my baby sv43 for reasons you state.

Hey Ryan, how would I get such a rudder for my same hull? Not critical to be black, but that is a sweet touch.
Thanks,
J
Actually I found it at MHZ. I got a couple stingers there too.

Jesse,

I've been buying all of my MTC hardware directly from MTC in Germany. Most of it's made to order, so the lead times can be longer than if you buy a part that MHZ has on the shelf. The advantage with direct is there are more part numbers, sizes, and options. He recently overhauled the shop and was calibrating a lot of new machines, which really threw lead times out the window this summer.

Where do you get your powder coating done?
Thanks Ryan!

Any progress on your end?

How do you make the glue joints so smooth and perfect for the motor mount? Do you use JB weld? Mine look so sloppy for comparison.

The MTC hardware on this boat is all anodized, done by MTC. The trim tabs were done locally. No progress on this project, haven't touched any boat in over a month and likely won't get back to it for a while unfortunately. I do hope, at a minimum, to get this hull painted this winter.

This build is all West Systems G-Glex, thickened with Silica, and dyed black. The key to clean lines is masking out the work area with tape. I've recently started loading my epoxy mixes into a 10ml syringe and using that as an applicator to get a more consistant bead size along the joint. There's less waste, and less overflow onto the masking tape.

JB Weld can be made just as smooth. A hot hairdryer on low speed will help it flow better and release air bubbles. You have to work in sections though, using gravity to your advantage, otherwise it will run everywhere. For example, on a motor mount, I'd tip the hull on its side, roughly at a 45* angle, and epoxy the outer edge on one plate, and the inner edge on the other, letting gravity hold the epoxy in place against the joint location. Once it tacks up (45min-2hrs depending on the epoxy, I flip the hull and do the other sides. The cosmetics definitely comes with practice.

This is my "baby" SV43 from Brusher Andy in Germany. It's 48" long, with about a 4.5" overhang on the back, and a stepped bottom design. His full size hull was 67" long, hence the baby moniker. The mold for this style hull was damaged and these are no longer in production, which is too bad. It was the best looking, scale version, in my opinion. My plan for the build is a single TP5680 motor on 12S, intended to run on rougher water at the lake we vacation at.

Andy is still making these. FYI.

Well, Jesse's progress has prodded me to make some time for this build. I didn't touch a single boat this winter. I laid out all of the rear hardware, squared it up, drilled some holes, and now it's mounted. I tacked in the rear motor mount, glassed in in with some carbon cloth, then went around the base again with epoxy for a little more strength. I laid carbon cloth down over the canopy front mounting tabs to hide all of the epoxy blobs I had to build up under each one. Added a little more strength, but mostly a cosmetic blanket that looks much better.

Still unsure on where the batteries and ESC are going to be mounted. I think I decided that last winter, but didn't write it down in my notes, and will have to go through those measurements again. I'd like to put the batteries side by side, directly in front of the motor, but then the ESC will need to be mounted on an angle to the side of the motor, or possibly directly over the top. The ZTW300A ESC is a solid performer, but so damn big.

Glad to be of assistance!

Had a dream last night about how to mount the servo using parts and materials I already had. Knocked it out this afternoon. Not the prettiest solution, but it's clean and more importantly, checked off the list. I made an adapter plate to use the existing mounting bolts from the rudder and then countersunk two bolts in the plate to mount the servo bracket. I can refine it this winter, possibly mill a sturdier bracket from aluminum.
