Thanks Dirk, happy with the result in the end

Thanks Mike, yep it took a lot more time than I expected when I started out :)

On the longest tow it went from motors ambient 32DegC to 40DegC. 100 DegC being the cutoff.

Any time mate, hey I wonder if your couch is still at Westonia Caravan Park :)

Howdy, no I haven't got it on gitgub but can share the code with you if you like

@@lukef9470 yes, pls. Can you share a link to the code. Thanks a lot in advance!

@@lukef9470, can't find a link from you with the app. Thanks in advance.

@@MultiRotorairview please excuse its a cobbled mess underneath, my LISP I have rewritten neatly and functionalised but the QML is still quite hacky, but gives you some key commands needed to do imporntant things. Please take some of the comments with a grain of salt, I have updated it a few times and some comments may not make sense drive.google.com/file/d/1IWptbYW8C2RKNODYdhp5th-PPABPPzg6/view?usp=sharing

@@lukef9470 Thanks a lot. Will try to provide a feedback.

I used lead acid all along. Just a cost thing. The LFP build would have cost 6k, lead acid was 1k. Once proven I hope to get funding to move to LFP.

Hey mate I hope to soon. I hope to pop code examples up to github soon also

Hey mate, ya that run was with a Trampa 100/250 running at the real top end of its rating. I have since replaced the controller with a 3SHUL 1000 AMP rated units with forced fan cooling and has no problems. The hand controller was the 4 + 2 Varient of the HOTRC DS600. They dont make that any more but they have a new version with a screen. conveniently the output og two of the buttons at the controller end where logic level which made connection to the VESC easy.

@@lukef9470 it looks like the really long one piece fairlead works well, don't need any rollers

​@lukef9470 there must be a controller that isn't made to be so lightweight and compact. After I fried my trampa I'm reluctant to buy another one in that format. Are you getting 2 step winches to work?

Howdy​@@embededfabrication4482 I would not use the 100/250 again without a waterbed heat exchanger. Things have been on hold due to health issues. I have run the 3shul seems to be OK. I would definitely have gone for the new trampa str 500 if it had been available

@lukef9470 I'm finally learning how to hang glide now at crestline here in So Cal so I gotta get my winch going. Looks like hang gliding is still popular in OZ, mostly paraginas here in california

Hmmm wrestling with porting my software to the 3shul right now. So works perfectly on VESC Trampa 100 250, but I had to write a whole new LISP section as I am getting a large amount more noise coupled into the ground I think which was false triggering the tow routines on the IO lines from the RC button channels to the GPIO pins. So thats nailed nice and tight now and perfectly stable. But I've spent several days trying to tune the motor, first with auto detect, then just applying settings that were reliably detected for FOC from the TRampa 100 250, no joy. Hackey is fantastic and cant fault the customer serivce and ongoing support. BUT I kinda wish I'd waited for the TRAMPA VESC 500 that you can now preorder with delivery december. TRAMPA are a known quanity to me and Frank provided great support. I have rooted around for years with this winch and the last thing I want to do is have issues with a controller that has now cost me over $2000 $AUD to land in australia. I got the idea the trampa 500 was going to be prohibitively expenisive but doing the sums it less than the 3SHUL :\ trampaboards.com/vesc-str500-100v-500a--p-35876.html

@@lukef9470 this electric stuff is expensive, I dunno if it's worth it. maybe a cap accross the power wires will reduce noise like they do with the drones. did you see what bobs CNC is doing with the GY6 powertrain? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VPotT-ulV7g.htmlfeature=shared

@@embededfabrication4482 Thats a nice setup

Howdy, I converted to use the transmitter receiver below, which a very high gain antenna on the reciver end on the full unit I finsihed. It must be the 4 + 2 varient. Allows manual control via stick and autonomous self tow cycle modes and auto rewind via the function buttons with the stick transitioning to a tounch sensitive "e-stop" in self tow mode.(1. Layout2.Take up 20kg tension 3 Launch Tension4. Full tension. 5 Roll off tow and release. F2 Rewind to 30 meters out, with various tensions set\configured via smartphone) I have unfortunately ground to a halt a few months ago). I have the software finished but really want to rigerously test the fail safes and logic before I shared it. www.aliexpress.com/item/1005004564257095.html?spm=a2g0o.order_list.order_list_main.5.ee1b1802Gx6ujE

Howdy, I'd just set the ESP32 port to use the internal pullup and then it doesn't matter if you voice modules IO cant source, just have the pin active low or use an invertor IC.

Howdy, the holes were more just mucking around in fusion when I was drawing it up. To really get heat sunk out in that area you need to add statorade to the air gap as the heat often stays localized to the stators and can't conduct easily across the airgap to the rotor. This is now not much of an issue as in my new full version I simply just got the biggest motor(12KW QS rather than the 3kw in this video) with the thickest windings and heat seems not to be a worry now. The line guide is just a yacht fairlead.

@@lukef9470 did you anneal the aluminum before you bent it to make the fairlead?

@@embededfabrication4482 Oh yep something I'm a little proud of there. So I tried many ways of doing this including annealing and not annealing, pipe bender with a few failures. So it is 25mm OD and 1.6mm wall thickness. That one in this video is actually not that good, on my full big winch I got a perfect bend. After many different attempts I found it very simple. So do not anneal the metal, I cant comment on thicker or thinner wall thickness tube but on 1.6mm no need in this specific case. In the part of australia where I live we have very fine beach sand. I got a bucket of nice dry sand and a funnel. I filled up the entire length, tapping it to settle properly as I went, sealed ends with duct tape nice and tight. I then made a simple jig out of ply wood sheet and a block of large dimensional lumber 25mm thick(I butted a couple together to make up the span of the radius. I just drew out the radius of my bend with a cheap timber compass and used a jigsaw to cut the bend shape. I then attached it to my bit of plywood, then used a g-clamp(kind of doing what a pin in a pin bender does and just bent it. Very repeatable.

@@lukef9470 I'm thinking of trying pvc pipe with wood dowel inside to make it rigid at the pivot, can counterbalance it too maybe, who knows, wobbling around a bit could wind the spool more evenly, my pivot is on a bearing so it's really easy to rotate.

Has gone well so far, in all honesty I stole the idea from someone who makes these commercially and seems to have performed well on their units. Voice control would be cool

@@lukef9470 who's winches? the guy in south florida? I got burned buying something made with pieces of scrap and garbage from a guy who calls himself "midwest jerry", that's what got me onto building my own. you can see a vid exposing his con on my channel.

I think the app is "vesc tool". The GUI you see is custom made using QML scripting.

@@joelsvensson341 I shorted out my VESC! There is an Indian VESC with more power

No probs,www.etsy.com/au/listing/1232357567/anderson-style-175a-3pin-plug-for-dcdc

Howdy, thats awesome to hear nice work. I built a customer radio module and has a high gain antenna which I elevate at the tow site, good for several Kms. If your 3KW is a QS I actually ran my old prototype 3kw at 9kw with no heating issues. Certainly not a guarantee over the long term though :0

@@lukef9470 I think I need to change my mounting system over to be more like what you guys have, I don't know if this turntable thing is such a good idea ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Du87JpWm3ds.html is your radio 2.4ghz?

Thanks Yes mate, I used the QML developer feature in VESCTool for the smartphone app and LISP for the automated functions

@@lukef9470 Nice! Im learning so much building this winch :) Is your code code open source? I´ve been looking at the skypuff app but I gave up.

@@n0s0ul333 Skypuff is a fantastic bit of software far above my development skill. But around the time I was about to tinker in C, Ben released the LISPbm functionality, I immediate saw that it would sidestep a lot of work directly modifying the C code firmware, which it has. Ben added tons of LISP macros that allowed me to do everything I needed. I have spent a lot of time on lots of safety fail-safes, once I have thoughly tested I will share it I think.

@@lukef9470 Ok, cool! I will dive into LSMP than! Great Thanks for pointing me in the right direction. Right now the remote and the linecounting is the biggest obstecle. But its such a fun project!

@@lukef9470 Wow, its very powerful. Love the way he setup frontend and backend. If you have a github let me know. We are two guy in sweden doing pretty much the same interface as your dooing. Your QML code would definatly speed things up. Today im going to test the towstates. very exiting.

Thanks Frank, when the VESC 500 comes out, we'll be pulling stumps out with it :) Ben's tireless work on the platform and the new dev tools probably cut a year off the development of this. Trampaboards commercially churning out high quality hardware to run it on was the winning combo.

yep I'd say maybe 30 tows or so, when I update to lithium it will half the size of the batteries and will increase tows to around 60 per session on one charge

Thanks Mike, unfortunately didn't get out to test in glider today, but we tested a number of the fail safes Saturday and had no issues with RC reception out to near 1km, this was without yet fitting the high gain reception antenna. Happy with progress so far.

Brad we fly many coastal sites and inland sites plus towing and there is an active community in WA. Our club in the Southwest is called South West Airsports. We don't have a web page but we have a facebook page that I (normally weekly) update flying that has been going on. If you have a look on there you can see many videos of flying that is happening. I understand one of our former instructors is just about to start the school again but not sure the details. However many people choose to use Rohan at Dynamic Flight who has an excellent reputation. He is based in Victoria. With cheap airfares to Melbourne it can be a good option and normally most people get there ticket in one week with him. Please email me luke.flecknell@gmail.com and I can give you more info if interested.

Heres a video of one of my fav flying spots in WA. This is Johns video of Shelly Beach in Albany ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o1o3-xGacxA.html

Thanks @@lukef9470, I definitely ran into mentions of Rohan and Dynamic Flight and they do appear to be very well set up for training, keen to go over and do that training. I live up in Tom Price - in the Pilbara. It feels like the air is pretty active up here and I can only imagine there is quite a lot of thermal activity and plenty of tall things to jump off haha. I'll jump on the face book group and keep an ear open! I come down South pretty often to visit family / do Drift events so I'll have to see when one of those lines up with an event you guys are running and swing past to get a feel for everything! Thanks!

Well looks like you've got one right on your doorstep :)(see link below), I have never flown there but my instructor a few years ago mentioned some big air up there . There are many flying options as well as coastal and mountains. Car Towing and very active aerotowing at the moment in WA, get pulled up behind a small plane . Search Mount Bakewell hang Gliding on youtube to see some of the inland action. Link for Mount Nameless www.dufty.id.au/hgawa/sites/nw/nw.html#mn

I can see Nameless out my front window :P, @@lukef9470 Haha, Used to Aero tow in normal gliders at Beverly when I was a teenager, there is an RAF limestone airstrip that I could vehicle tow from near by as well. Thanks for the other local link!

Andrius, a local Hang Glider pilot created this. Let me know if you are interested, I am sure I could arrange a package but have to ask Dave if he has some in stock. Let me know
