Oh it will return this year alright
Printed up some tube bending guides. There was some hose kink issues to sort out
Squeezed into the tube
looks like its working (port gun was issue)
Making a new box because of need for another servo lead
decided to use triple xt30's for servo connections based on impact of loss of signal on the brushless ESCs. The fit is very tight so definitely need dielectric grease
I've looked for triple-plug XT connectors, but have never found them - where did you get those?
Box sealed up (marine 5200)
sprayed deck and superstructure
Super in place, glue down tomorrow. Should probably add the secondaries before ballasting. Also maybe program ESC, power the boat up, and take first cut at transmitter settings, sheet Friday, co2 lines at some point, systems check and sea trails remaining
Gun barrels in, pulled out radio and centered rudder, other small things
will use stack as float, printing spool tomorrow to go in the hole there, will fill stack with foam
Knocked out ugly spool, hopefully should work
New box is done (need to cut off mounting tabs). programmed the pump ESC, also tested out the drive motors. Didn’t cook anything yet. The cracking point on the outboards was higher than I anticipated ( dead band), but I got them legal. It’ll be interesting to see how she behaves on the water. Also looking forward to testing hobbywing brushless ESC on drive in terms of reversal time vs hobbyking (still need to wire hobbywing up).
Ready to start putting things in for real
Did the duct tape thing. Overall it went well, but probably took 1.5 hours additional, so i think it will be awash from a time saving perspective, with small variation based on the specifics of the boat. For a long boat like that that i can't soak in the tub, the savings will probably be positive, for a smaller boat that could be soaked prior to removing sides, the savings would probably be negative. for a slab sided boat it probably would work well, this boat took longer due to stringer (2x windows to cut out)
documenting window depth
Hole for wires and rib to sandwich the motor mount so it doesn’t pivot to touch the motor
I was wondering, What type of screening material did you use for the internal armor?
Pet-resistant door screening
Got wiring hooked up and co2 lines in
Small things add up, 30 lbs with 2nd bottle. Bit heavier than I want so going to stick with one for now
center of gravity within 1/4” of planned
Co2 lines much cleaner than wiring. Gun testing went well besides some co2 leaks that took a bit to correct. Hottest guns I’ve made to date. Grouping generally good but might have a burr in one of the barrels, I’ll have to check
Superstructure gooped down, secondaries made up
blocks to align stack
Small things tonight. Gooped some wire holders to underside of deck rim, also showing aft superstructure mount since that piece spans two deck pieces
grip is strong
Battery mounts (black things in bottom)
barrel condoms and barrel pins
Wound about 15ft of braided fishing line around spool
let’s hope my float passes muster!
I sprayed the secondaries, so will glue them on tomorrow. Otherwise it’s just wrapping the wire bundles and dielectric in the connectors I think.
also tested out Courbet tonight, everything checked out. The monitor powered on too, it will be quite the odd ball fleet going to Georgia. Still have a solid evening of gathering things for the trip and packing the car. First event of the season always takes longer to gather things that migrated over winter
Gluing the secondaries down, I’ll have to figure something else out for the aft ones since they would interfere with deck hold downs (plans never arrived haha).
Will be putting the finishing touches on pond-side! Hope it works
first battle in the books, great event in GA.
awesome shot by @Beaver
she had some teething issues and will need some changes to internals
Damage I contributed to
damage received, tis just a flesh wound. She took 117-15-50ish like a champ
Time to start the first post-battle-one refit
Boat did ok for sea trials/battle one. Balance was a bit off so had to add weight to the bow, ended up running near max weight. Sidemounts were great, stern guns needed work - too much air flow for 1 reg, had to scale them back a bit. Boat spun after some adjustments, turns out I made rudders to the old rule size so I'll have to increase them to the current limit. outboard motors worked great, backed up straight. pump did well, might try out the 1350kV I have for a comparison to flow vs amps
Measuring the new center of gravity with the trim weights for reference, about 1" off pre build estimate.
moving bottle to bow, batteries slightly forward. This will allow reducing weight by a bit.
Box probably going away, it will leave space for the three ESCs directly forward of motors. Probably will just make a new wire harness
Once that's all sorted out, I'll have to work on the stern guns
You're making me more certain that my next project will be a refit of my rookie Scharnhorst!
No one deserves the pain of a rookie Scharnhorst haha. I’m certainly happy with how she did in battle one, I feel like rumors of her sucky-ness were exaggerated. Should only look up once I check several things off my improvement list.
anyways, got a little bit on time to work on wiring. Preserved the main harness with some minor mods (octopus for aux power leads). the three ESCs will sit much closer to motors, a lot fewer connections and wiring
need to wire up gun boards and pot
Not much boat time recently, more time in last couple evenings
found out why rudder servo stopped working
Disappointing performance for a single event with no sinks. I used some old fashioned waterproofing on the replacement (with current products), conformal coating on the board then e6000 around all lower joints. Seemed like the weak point was the wire boot, so that had all surfaces hit with e6000.
boards are wired up and tested, bricked the receiver and transferred settings
got mounts in for new arrangement. Here’s a bottle mount that snaps onto the athwart ships battery I drew and printed tonight
overall new layout
Balance is much better, allowed removing a lot of trim weights. Total boat weight will be around 30.5 lbs.
need to run new co2 lines. Planning to use the 3oz bottle for just the third triple. New rudders are in the works. Should have it at oakboro ina a couple weeks
