Outerlimits SV43 build

[fweasel]

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.

Step 1 was to figure out how to secure the hatch. It had no pins or lip. The angle of the front of the canopy made this project particularly difficult. Because there wasn't a lot of material to work with around the lip of the canopy itself, I decided to use carbon tabs instead of pins. Mocking them up and getting the slots cut in the hatch lip took a lot of work. Then I tacked the tabs in place, and built up a fair amount of epoxy and chopped fiber around each tab inside the canopy. Everything lines up and slides in place nicely. I left room for a neoprene hatch seal and will install two blind nut hatch locks on the rear corners to secure it in place.

Next up was installing a solid carbon transom doubler and mounting the MTC drive. I made a quick template, and cut the carbon plate on the band saw. Epoxied it into the hull with G Flex, loaded it full of lipos for weight, and let it sit overnight.

I wanted to use all black hardware on this build. The only drive I could find that was 1/4" flex with a 3/16" propshaft, long enough, and available in black was from WD200. Werner got it sent out from Germany pretty quickly, in fact, it was the first part to arrive! Can't believe how much room is in this hull compared to the small cats I'm used to.

I've got my motor and ESC from OSE, but waiting for the mount to arrive from MBP and the rest of my hardware from MTC in Germany. Trim tabs are with kfxguy getting powder coated. Once the parts are here, I can start mocking up my CoG and figure out where the batteries are going to go. Still undecided if i'm going to run 12S1P or 12S2P. The additional weight won't be a problem, it's a question if I can find a place to put it.

My baby

Ya Ryan! I’m so psyched to see this build thread!
I have one too... just painted, no build yet..
I was told that this was one of the last babies... (the Lucas)
I was thinking twins?!?

[vvviivvv]

Similair to my H&M, its about 110cm overall it had a 5850 1000kv speeds ~ 65mph which ive replaced with a 3060 and cracking 75mph on a fairly small prop.. prather S235.

Bought it for windy days when my hpr 115 / 150 aren't much fun.

Our hulls were both around the same age, and at the time, they were some of the last built before the mold was damaged. I just heard from Andy today, that the mold has been fixed.

Progress?

[fweasel]

Basement flooded recently, dealing with that. Motor, water jacket and ESC are here, but rudder is waiting on black anodizing at MTC in Germany and MBP motor mount is en route from a friend in the UK. Was hoping to have it running for the 4th of July vacation trip, but that's not going to happen.

[fweasel]

Not much progress to report. Got my Speedmaster trim tabs back from powder coating. Turned out great.

Ooo black satin.. sexy!

Made a little progress on the SV43 today. Nothing is glued yet, but the motor mounts and stuffing tube are all mocked up. Took a lot of time to clearance the motor mounts to fit the contours of the stepped hull. Had to sand the rear support on four different planes! I needed everything to sit as low as possible to keep the flex angle reasonable. Not sure of the flex cable I'm using is too stiff or not. Big change from the 3/16" cables I'm used to. Wondering if I might find something more flexible to create less drag. Hope my MTC rudder shows up soon. Been waiting on that delivery for quite a while now.

Looking really good Ryan!
1/4” flex?

[fweasel]

Looking really good Ryan!
1/4? flex?

Thanks. Yes, 1/4" flex. It's pretty short and a 3/16 might have held up, but it didn't seem worth the risk. I just hope the cable I used is flexible enough and doesn't cause too much friction.

I'm glad to find your thread Fweasel. I just ordered a 59" SV43 for a first time build. I'm chomping at the bit for it to arrive and Steve here at OSE is being awesome at recommending equipment, ie. motor size etc. Please keep posting your progress! I will be watching and learning. Thanks!

oh dang, I need to check for new threads more often. Definitely following this one! I'm itching to build another mono, but a little smaller than my 70. I sure do like this hull, such a shame they're not available anymore
