Continuing right along with the build,
Servo Box in the midst of printing
Note the two support bars for the stepped rudder servo section.
Servo box & mounts installed, just sorting out the timber to re-attach the deck
Once the deck is reinstalled the RC receiver will be relocated under the centre of the rear deck well out of the way of any water that may splash in.
Close up of Servo Box & Mounts.
The Servo Box mounts are 12mm x 6mm x 110mm 3Dprinted rails with 3mm Nyloc nuts moulded into the bottom. These are then epoxied into the hull.
The 12mm x 12mm x 110mm aluminium angle is epoxied & screwed to the Servo box & then screwed to the mounting rails with 4 only 3mm x 10mm Stainless Steel Cap Screws.
This makes for easy removal of the entire servo tray with everything intact by just removing the 4 mounting caps screws.
Need to make up a timber strip cutter in the morning to rip the deck mount strips down to the correct size then the deck refit can start.
Can’t answer the question about my hair as even then I couldn’t see the top of my head however way back then (2014) the onboard video was rather rudimentary and the actual video recording was all done on the Ground Station.
That camera is still working and is currently the auto switch reversing camera on the Axial SCX10 Rock Crawler.
I did manage to get the Bix 2 airborne on a couple of occasions with a GoPro 2 installed on a great big CF Pan Tilt (which I still have). Will try and find a pic or two & maybe an old GoPro video. This was one of our early attempts at in air recording rather than using the Ground Station.
Things have changed a lot since, but even way back there I had Pan/Tilt control on the camera.
There were trees (that Chris was always flying around, through, over, under etc.), just that they were further up the hill, there were heaps of fences but the paddocks were much larger and the landing strip was flat for sure but very bumpy so ALL take-offs were hand launch (you learnt how to do it or stayed grounded) and it was generally very windy (but at least it was constant in speed and direction).
And of course there were cows, lots of cows much like The Farm, and not to forget the model Helicopter flying field only a couple of paddocks over.
Yes, an ideal place to learn to fly.
The ways of the world (according to the frog) are strange and wondrous things, just a shame how the truth of it all gets lost in the telling!!
I think his avatar may explain a lot, but we love him just the same.
No worries Tug & welcome to the forum.
I made a slight stuff up with the servo tray so am just in the process of printing another (hopefully correct this time) one.
This time I remembered the step down for the rudder servo.
I had Ron B (of Ron’s Reef fame) over this morning with his V2 Mt Gay 30 that he is also in the process of rebuilding. Have supplied some ideas & printed a couple of bits for him so hopefully we will have 3 on the water before not too much longer.
Ah yes, Bad Angel & his drone attacks, too much spare time on his hands methinks.
Got the servo box designed & printed (10 hr print) yesterday so hopefully get the servos fitted & all reinstalled today.
If I got the measurements correct there should be room for both the sail winch & Rudder servo, as well as a 5 cell AA NiMh battery pack.
Keelbox & support bracing is next on the list for 3D printing.
Design is complete & printing now underway.
Keelbox & bracing to go over & secure the alloy keel fin to the hull
Once this is epoxied in place the Servo tray can be completed & installed then I can think about refitting the deck and making sure it is sealed this time, which is where the job started
Update:
Keel box now installed.
The keel fin has now been fibre-glassed into the hull & reinforced with woven glass mat and the forward bulkhead (in fact the ONLY bulkhead) that sits under the mast has been reinstalled & epoxied into place.
Keel fin & forward bulkhead
Next job is to finish off the design of the new 3D printed Servo Tray and get that fitted so I can see where the keel fin bracing needs to be installed.
Seeing as I’m stuck inside on this cold, wet & windy day its a good time to get things done so moving right along with the repairs the new rudder support post has been designed, printed & fitted to the Badger II.
The 3D design ready for printing
New Rudder Support Post- Printed & epoxied into place
The original Rudder mounting block that had come unstuck from the hull
After a recent sailing @ Puddleduck chasing another Mt Gay & a few DF65’s the poor old Badger II was found to be carrying a significant amount of water ballast. With so much water inside her it was easy to spot the leak.
It turned out that virtually the whole hull to deck join was badly leaking so all the previous work waterproofing the hatches was having little or no effect.
At first it was thought that some self levelling epoxy poured into the inverted hull may have been enough to fix the problem but on closer camera inspection of the joint from inside the hull it was decided to remove the entire deck and start again.
The timber Servo/radio/battery/keel mountings had already been removed as they were showing signs of water-logging over a long time & their removal allowed for easier internal access to the hull.
Control Gear Timberwork & bulkhead removed

The hull (with deck removed)
I guess glues weren’t as good 20 years ago or else “Badger II” was built more as a display model but whichever the reason there was very little persuasion required to get everything unstuck with the only damage being the rubbing board around the deck which came off in quite a few pieces.
First order of the day will be fibreglass the alloy keel into the hull then 3D print & install mounting braces for the keel & rudder post. Once that is done then a new timber deck mounting rail will be installed & sealed followed by refitting the deck after a bit of a clean up.
Not sure yet but I may just fit a new deck entirely as it may be easier.
To Be Continued…
I’m not sure what Ricky’s weighs, it was more just a check to see if the weight goes up or down with the new 3D printed parts in place of the wood.
Another fine day @ the Duck, enjoyed by everyone, even with the weed in the early races.
As for the water leak alluded to by Col in my Mt Gay 30 (it was definitely significant but in no danger of sinking).
Anyway, the “Badger II” has been stripped down and all the old timber servo & keel mounts removed to give good access to reseal the inside of the deck to hull join.
I guess after 20 odd years things have got to fail eventually.
During the rebuild all the removed timber bits & pieces will be replaced with lightweight 3D printed bits.
The alloy keel fin will be fibre-glassed into the hull. This will be a lot sturdier than the original timber sandwich mount which was showing signs of being waterlogged one too many times. The servo mounts were also in similar condition.
For those that were enquiring today, before the strip-down the Mt Gay sailing weight was 3.33kg all up.
