What did you do to your boat today?

[785boats]

It is an ML Boatworks Winston Eagle Lobster kit that I converted into a canard configuration.
In its true form I understand that it is a very good boat to run. But you'll have to speak to those that have built it properly on that.

Checked out your build thread, that was great! The vids were good too. There’s some weight dynamics going on with the boat in the turns. It’s screaming a message at me! There was an Unlimited built very similar to this boat.. It had weight transfer issues.

Probably best not to get into that discussion in this thread though. But I would like to hear your thinking on it.

[CraigP]

Agreed. I’ll PM you...

Wanted to share a few pictures of my Stealthwake that I've been working on today. Getting it ready for indoor pool racing next weekend. We're limited to a 2S battery, no larger than a 45mm plastic props, and a max length of 34" offshore style hulls.

I borrowed my Leopard 2850 3580kV motor from my Offshore Infinity and modified the existing motor mount to accept a 25mm hole spacing. While modifying the mount, I realized it was the same mount used in my Zelos 36, funny, but it makes sense that they reuse as many parts as possible. The stock boat uses a 3mm solid shaft so I ordered a 4mm to 3mm brass coupler from Amazon and it spins surprisingly true. The holes are bored dead on to the advertised diameters. The only downside, it shipped with the wrong size grub screws so I had to order some M4 x 3mm stainless flat bottom grub screws from McMaster Carr. They'll be here Monday.

The stock boat uses 1/8" (3.175mm) bore props, but as I mentioned, the solid shaft is actually 3mm. I shimmed the prop shaft behind the drive dog with three wraps of scotch tape. The 1/8" to 3/16" prop adapter not fits snugly with no wobble. Luckily my 3/16" plastic 38mm prop slides right over the adapter with no slop either. I have no idea if 38mm is the right prop as this boat has never been run in this configuration and all the water outside is frozen solid. I've got 32mm, 35mm, 40mm, and 42mm plastic props to use as well if needed. Heats are 3min long, so who knows. Arrover did most of his 2S runs on 45mm sized props, but at a much slower RPM using an 1800kV motor. I'll be spinning faster than he was on 3S, so it seems obvious I need to be smaller than 45mm in diameter.

Finally, the stock rudder was a sloppy mess. I had an unused Speedmaster mini rudder from a Delta Force 26 project that hasn't been started, and it was the perfect size. I centered the mount directly over the existing pushrod hole, marked up the transom, and drilled four new holes. It bolted up easily and I used silicone caulk to seal up the old mounting holes for now. The stock boat has a through hull water pickup under the hull that I'm using for cooling, so the water inlet in the Speedmaster rudder won't be connected to anything for now. I had considered capping it off, but decided to leave it open in the hopes it squirts water straight up like a Yamaha jetski.

It's been covered before that the stock driveline angle is less than optimal for speed, but I'm choosing to do nothing with it for this quick build. The races are not all that serious, so I'm more concerned about making it the full 3min without sinking vs. ride attitude. I had considered raising the stuffing tube exit hole in the transom, but because its a solid shaft, I would have to redo the motor mount inside the hull to match the angle. Too much work. There's another pool event in February, and maybe I'll redo the drive line with a flex cable then.

Just about finished with my Joysway Offshore Infinity project that always seems to get pushed aside for something else. I made a new mounting plate out of carbon for the steering servo and new, larger ESC. I relocated the battery mount rearward and up against the side of the flood chamber. I'll be running a Turnigy 3S 2200mAh battery which gits perfectly. I also cutout a support rib for the right side of the hull to brace the side of the hatch opening that used to deflect easily and cause a leak when the hatch was on. All of the hardware has been remounted. The turn fin was repositioned to be square with the bottom of the hull and the trim tabs were trimmed and raised about 1/16" above the bottom of the transom. I need to make a grommet for the hole where the cooling hose passes through the transom to keep water out and make a very thin seal for the hatch opening. Hope to have it in the water this week.

Don’t know how to post a pic yet but moved a SF ESC into my grandsons mean machine ,got it all hooked up ,just need to bind the spectrum radio in the other boys revolt and their boats are ready ,

[TRUCKPULL]

Replaced the two motors with TP 1570kv 4050's
New custom coolers from HamR/C 70mm long left and right water inputs.
and new plugs all around.

Started installing my rear motor support rings in the Zelos to support the heavier motors. Modified the motor wire trim to make room for the ring and water jacket. Don't have a millimeter to spare. Tacked the bottom portion of the mount in with 5min epoxy. Once that sets, I'll pull everything out, do some light sanding, mask, and glue it in with dyed JB Weld.

Only had the boat on one time last spring after the electronics overhaul. One of the motors shifted and the wire drive sheared at the collet. This will stop that from happening and hopefully I'll get the boat back in the water this season.

For the last 3 days I've been conditioning some new SMC 3s 5400mah 90c lipo cells for my Sonicwake.
I have to say it's just a little more exciting than watching paint dry.

[785boats]

Watching & listening to lipos charge is one of my favorite past times.
I've gotta get a life.

Happy Easter mate.

Paul,
From what I've seen you post your life is a pretty good one
Happy Easter to you too mate.

[785boats]

Yeah! I can't complain.
So in keeping with the theme of the thread, I've decided to do some maintenance on a few boats.


This morning I replaced a set of bushes in my little Restricted mono. Well, I say replaced, but the rear bush in the strut just wasn't there. Totally gone.
Since the bushes are only about 5mm long I put two in the front & two in the rear. Feels a lot better now.

I also set up another car heater demister unit to discharge 6s packs. This one is a 300w unit at 24v, so a bit less on 22v. Still, it will bring down a 6s pack reasonably quickly.

The rear end of the Rocket, my restricted mono.

Paul,
What size prop are you running on that Rocket?
