Just float tested the Atlanta. It's a pound under max weight. Even in this light condition, floating level with excellent stability. Fired her up to test thrust and all I can say is... Will try to get it out on the pond this afternoon with video hopefully. ...
Wind and cold couldn't keep me from the lake today. Except for being severely overpowered, I was quite impressed with the first run. It was to cold to muck around with throttle end-points but I imagine I'll have to crank her down 50% or better to make 22 seconds. I'll have to tighten the deck seals as this ship bury's the deck edge on turns. Pump is working fantastic. No priming issues whatsoever. After ten minutes or so of full bore driving and pumping, still have three bars on the battery pack. ...
Very nice Steve. It almost looks like we were watching sea trials in fast forward. You might even be able to keep up with the Nassau's. How do you think the battery will like being under water?
The model was sunk in the bathtub with the battery in. The battery then ran the boat at the lake two hours later. So far, so good. These Lowes Kobalt batteries come with a generous coating over it's charge controller board from the factory. I added a layer of e6000 over that. FYI, these batteries have the built in voltage leveling, the charge meter, and over amp protection. What it does not have is a low voltage cutoff . Not complaining to much, as their only $20. ...
Stability leaves a lot to be desired. At least it rights itself after a turn, but wow, is that 30+ degrees of heel?
If you want to race I have a cattamaran that I think may just barely keep up with that thing. Jeez brother what piped nitro engine did you rob off a race boat for that thing lol. Looks good once you get it slowed down lol.
Rudder torque roll. My Mogador does the same thing. Hopefully it will be more manageable when it gets dialed down to 22s.
Right know it's at 8.1 pounds. I'll be adding a 1/2 pound of ballast. The battery is a Lowes Kobalt 24v 2AH power tool battery. ST
Tightened up on the deck seal. Basically, I spread hotmelt on the subdeck and then snapped the deck in place. This molds the hotmelt to fill in open areas. The rest squeezes out of the sides and is trimmed off. 1: Grease up the underside of the deck so the hotmelt doesn't stick. 2: Tape the subdeck to keep grease off it. 3: Peel a few inches of tape back and apply a bead of hotmelt. How much you do at a time depends on how much your gun can push in one shot and how quickly the hotmelt will harden before you can snap the deck in place. Three inches at a time worked well for me. 4: Snap the deck in place. Let harden, pull the deck off, do the next three inches. 5: Once the side is done, trim off excess hotmelt. 7: Repeat on the other side. ...
if you had the same lack of deckseals on calm water, would it have been as bad with regard to taking on water?
Yep. These little boats (at least mine) will dig their decks into the water on a turn. Since I use removable decks, a good deck seal is a must.
