Sorry about the late reply Tug, to be honest the weather over winter so far (apart from the last week) has been pretty decent for winter. We haven’t been missing too many flying or sailing trips and most days I still manage a 3k or 4k walk with Pyro.
He does like a nap in sun when we get back though.
Anyway looks like the “Double Trouble” project is back on track – well for a little while anyway.
After a fair bit of hunting around to find all the bits & pieces (after all it is 4 years since she was stripped down) the work is finally under way.
Cooling tube holes have been epoxied over and had a light coat of spot putty applied so the hull is now ready for paint preparation. After another quick rub down & tidy up, a coat of primer followed by spray putty on any rough spots then a final primer and several top coats.
I was going for deep blue originally for the underwater area but as I have black in stock methinks it may end up black below the waterline.
Motors & ESC’s have been temporarily installed and the alignment looks OK. Once the drive couplings turn up final alignment can be set & the electronics permanently installed.
I’ve opted to install the ESC’s in the cabin area (below floor level) so there is plenty of room in the rear for batteries & video gear etc.
You will usually find colours are much more vibrant over a light coloured primer, either white or light grey usually work best.
Polyurethane over the cardboard first should seal it OK, also a thin coat of bondcrete works well (and is far cheaper) to seal cardboard, timber, foam etc.
Today it’s time to start again on “Double Trouble”
I have finally managed to source the correct universal joint couplings (5mm x 4mm) to connect the new brushless motors to the propshafts. No doubt they will take a few weeks to arrive from downtown China so in the meantime I’ll remove all the watercooling pickups & outlets that were fitted to cool the brushed motors that were fitted when the Outboards were first removed.
The brushless ESC’s are aircooled (fan assisted) and the motors are so oversized that they barely get warm so no additional cooling is required.
Inlet & outlet pipes have been removed so next job is to fibreglass all the holes then the bottom of the hull & the rudders can be painted.
Also need to manufacture a timber stand for storage & display purposes.
Thanks Mr Moose, it’s still not quite right but its getting closer.
I tilted the mast forward a bit today so see what happens next sailing day.
Hoppy, here is the link, it is available at the top of our links page.
Don’t know if Miss Piggy will be able to handle the additional weight. Looking at her last jump the descent was quite rapid so I’m guessing she has been pigging out again and stacking on the pork.!!
Video from the first day of flying the S800 Sky Shadow wing.
All in all it went much better than I expected as the only other wing I had flown to date was my X-Vert VTOL wing.
I have now changed from a 6×4 – 2 blade prop to a 6×5.5 – 2 blade.
Motor current has only gone up from around 14.4A to 16.5A so still well under the ESC limit of 30A
I will also activate the Auto Launch function in the iNav FC and try and dial back the stabilisation slightly to stop the wing rocking @ low speed.
Thanks Chris, however if you dig a little deeper you will find that the full name of the S800 is in fact a Reptile S800 Sky Shadow (sold by BG & HK). The V1 is generally Black and the V2 is generally Grey. The V2 also has a vented canopy and supposedly the build foam is denser & more solid.
