Shockwave 26 Repower/Improvements

[Tamelesstgr]

Hey everyone, I started updates in another thread, so I wanted to start my own build thread. Backstory is that I bought this for my son last summer. Learned a bit about batteries (one dead on arrival from Proboat/Dynamite). Was pretty fun running it during the summer, fast enough not to get into too much trouble, and about 8-9 minutes of run time with the stock bruched motor and 8.4v nimh 5000mah pack.

This year my dad bought a PB Blackjack 29 and will be running 4S, then my uncle picked up a nearly new SV27 and he will be running 12 cells nimh, so we obviously needed up step up our game with the SW26!

Thanks to Bruce on the board we are set up with a 3000kv brushless motor and ESC to run a single 8.4v nimh 5000mah pack. I wanted to address some hull issues so I ordered Kintec 2 part foam to add some flotation. I need to fix some transom cracks with Epoxy and get her painted. We came up with the name Slingshot since we want to try and hang with the big boys.

Pics of the Foam I did this past weekend, and the initial concept for paint layout.

Transom cracks, and I need to add some epoxy to the sides of the inner / outer hull since the white bond was brittle and was removed.

My custom made engine cover from a toy car hood scoop. I just started cutting and figured out something that worked.

Mock up of the new power, I want to add some fiberglass cloth and epoxy near the motor mount. I also need to bend up a metal servo bracket since the plastic flimsy one broke on me.

Added some more epoxy last night, still need to tackle the other side and the transom.

Does anyone have any tricks for getting a nice even pour of epoxy into a certain spot? I have tried a slow pour and tilting the hull in a direction to allow the epoxy to flow where I want it to go.

A syringe

Ah, that makes sense!

All of the epoxy has been added where needed. Need to start sanding the transom flat and then scuff up the hull while I decide on the paint scheme.

Hows the progress on the boat? Im waiting on a few parts to come in and my new 3s lipo packs (2) to get my boat singing across the water :)

Really interested to see when i start cutting the plastic away from the transom how flemsy it may become. i dont anything on the back to move and a LOT more weight is being added with new 5" rudder assembly, adjustable trim tabs, cnc prop, stainless bullet for prop and 8mm tubs... hmmm maybe a layer or so of FG might help if i feel like drag might buckle the transom or allow it to move. anyone have that thought or have worked with plastic hauls before?

There is some re-inforcing on the transom on the Shockwave 26, but I would suggest adding more. I am not sure what material ProBoat used, it may be a wood or plastic backing up the transom. As you saw, just adjusting my trim tabs caused the stress cracks.

I hope to get back to this project next week, the weather is getting nice.

Made a little progress on my crude trim tabs and turn fins. Using my scroll saw with a metal blade I cut these shapes out. I need to make sure they are square and sand them down on a belt sander. I was going for a little more curve on the turn fins, might try to shape them more on a belt, the scroll saw wasn't very smooth, might try a finer blade.
