After charging up the batteries it looks like I only used 5.178amps during the two sorties. So that means I should easily have plenty of juice for two action packed sorties with lots of running and pumping.
Couple photos of the damage taken at the Regionals. Port side bow. This was mostly from Rick. Starboard side amidship. Port side stern. Some of this might be from the undisclosed Allied gunner. This part is mostly for @Trey Schultz. At the regionals he was curious as to how I installed collars in my impellers. Here you go. When I design my impellers I put a cavity in the base for a Dubro collar to be welded into. This usually has to be drilled clean before installation. I also have a hole running through the side so I can tighten the setscrew. Installing the collar is pretty straightforward. Use acetone to soften up the ABS of the cavity where the collar will go. (a little extra slurry added in can help fill up any gaps) Then screw the setscrew of the collar all the way in and insert it into the cavity of the impeller with the setscrew lined up with the hole for it. At that point, just screw out the setscrew, make sure the collar is level, and let cure. I must say that this isn't all my knowledge. Most of it I learned from studying the impeller of a 3d printed pump I got from @Tugboat. That pump is still going strong Tuggy, in case you were wondering.
Here is the video of the speed trials I promised. Enjoy! View: https://www.youtube.com/watch?v=PFPjB5nhmi0
Yep, I shot at your boat. But to be fair, that little British naval ensign on your foremast looked a bit different to my 54 year old eyes.
Yeah, the perils of running a British flag. Doesn't even save me from my comrades. Don't worry though, next time it will be much bigger so you can see it, Steve.
When I embed the Dubro collar into the impeller, I take a dremel with a cutting wheel and slice 4 slices into the outside of the collar, and mush some slurry into them; I think it locks the collar into the impeller better than the smooth surface of an un-modded collar Very happy to hear that the pump you got from me is still kicking
Built some new motor mounts for the King today. Brushless will teach you the deficiencies of plastic. New mounts made of aluminum. In the boat, but not glued yet. I suspect these will last much longer.
Took the King Edward for a spin today on the pond so I could test the guns and get some cool video. It's also a continuation of my 'ship vs. log' saga.
That was the second time I got stuck on a tree that day. Hmmm, maybe I need to hug more trees. For now. Spent a couple hours the other day tweaking each gun till it fired satisfactory. I'm not totally happy with them yet, but they work well enough for now.
Had a good time at Ming's battling the King. The boat worked well besides having a little trouble with the rudder servo. I have a list now of things I'd like to improve and make better. Nonetheless, the King is a fun boat to run and I look forward to tangling with more Nassaus in the future. Till I get to posting photos of the updates I'm doing, here are some damage photos from Carl's. I put my action camera looking down the stern sidemount barrel and Carl couldn't resist being on camera. Hopefully I gave some of that back. This damage was from the second sortie of the second battle (in which I sank). Took some pretty nasty damage. lol That gaping hole is either from Carl or Brennan who was driving Carl's turbocharged Espania. Enjoy!
This last battle I had trouble with the pushrod linkage for the rudder binding. This resulted in several instances where I was stuck going in circles. Doing away with the pushrods and moving to something else. Not sure what, but I'll figure something out. Also bumping up to a full size servo. Made a new servo mount. Fabbed up some tight-tolerance SS barrels or the dual bows. Very nice. Soldered up this accumulator tank for the bow gun solenoids. Sits nice in the bow. For the new rudder setup, I've got a couple different options I have been mulling over. Simple option would be 3d printed gears. I might go that route, but I might try GT2 belt or even a tubing belt setup. I'm going to experiment a little and see what I like best. Should have something I like done here soon. Enjoy!
Finally completed my new rudder setup for this boat. Using GT2 belting. There is a 3-to-1 ratio on the pulleys so I get plenty of movement on the rudder. Built a new rudder that sits closer to the props per @Kevin P.'s suggestion at Ming's. The rudder is stainless silver soldered to a brass shaft.
