Shockwave 26 Repower/Improvements

[Tamelesstgr]

I really need better fabrication skills lol, trying to make nice tight bends is challenging, but I managed this servo strap since the plastic ProBoat piece broke on me last year.

how does it tie down? glue or screw?

[Tamelesstgr]

Screws, but I need to get some stainless ones and drill the holes for them in the bracket.

Making some slow progress, trim tabs and turn fins mock up (and side by side pics against stock ProBoat combo):

What did those bigger tabs come off of?

[Tamelesstgr]

I made them out of some flat stock, see posts above ^^^

Things should start getting serious in the paint department this coming week. Didn't want a bunch of fumes and over spray in my basement, so I built a temporary spray booth in the garage.

[Tamelesstgr]

Finally starting the painting process!

Well, I am pretty happy with the basecoat paint job. Frog tape worked very well in my opinion. I was going to mask and spray logos, but instead I am looking to have some UV vinyl logos printed. Meanwhile, pulled everything together last night, should be testing in the water this weekend!

Well, it was an "interesting" weekend of testing. 3000kv setup with 45amp AQ esc is performing better than the brushed setup that was originally in the boat. Still turning the stock ProBoat plastic prop, I have other sizes to try: 40, 42, 45, 48, but I need to get my battery and esc ends changed to XT60 so I can hook up my wattmeter. I'd like to do some testing in the tub before letting those larger props rip out on the lake. This setup is no match for grandpa's BlackJack 29 on 4s.

My son did manage to flip the boat, and the hatch popped off, and the inner hatch too! Within seconds the Shockwave 26 had taken on water and was bobbing there in the lake all by itself. Panic set in lol! I hopped on my buddies waverunner and retrieved the hull and canopies (thankfully) Dried everything off and was sure glad I added extra foam flotation in the nose and coated all my electrical connections with corrosion X. Retested (with hatch tape) about 30 minutes later, and all systems were functional.

Still need to finish up some logo work, paint windshield, and final clear coat.

Whatever material I used to cut the trim tabs and turn fins out of is rusting, so I will probably bite the bullet and purchase some official units.

here's how mine looked after the intial foam treatments....

The entire left side is now filled in and the high spots sanded down. Need to add a bit more to right side, then finish sanding to bleand everything in.

Last batch of foam I got expanded too fast in one of my boats & f'ed up the hull. So gotta do experiments too figure out what caused that - bad batch??

In of his posts Darin Jordan mention marine foam becoming like a sponge (absorbs water) if sanded, so I'll spray a couple coats of clear to put the sheen (and waterproofing) back on.

NO - those custom jobbies you did are very nice!! - Just need to make another set out of the correct materials... http://www.ksmetals.com/30.html - Given the rust issue's I've seen in your pix I would go with SS for obvious reasons.

With your setup I would try a CNC alum or S&B Octura x442 if you have access to one. 45 & 48 are going to be too big for your setup.

Also try it out on a 2S pack (30C minimum) & see how she does. 2S off the charger = 8.4v same as your NiMH but LiPo's pack a lot more wallop.

Because that ESC doesn't have LVC \ LVD you'll either need to time your runs & get one those cell voltage checkers like \ similar to this one... http://www.hobbypartz.com/ms-battery-voltmeter.html - they connect to the balance tap so need to disconnect \ the main battery leads.

You'll know when the battery is getting tired because performance will really fall off - that's how I do it with my mini boats becuz the ESC's in them don't have LVC \ LVD.

FYI: I get 15-mins easy with my SW26 on a 4000mAh 3S pack - our setups are very close.
