I open sourced all the Fusion 360 files and the Arduino source code. I'm also open to sell the one you see in the video. I plan to make some upgrades over the winter and would rather sell this one than cannibalize it for parts. PM me if interested.
Not sure a different prop will make a meaningful difference on noise, i.e. it will still be loud. Also goal is to launch find thermal then cut motor, neighbors can live with 10min of noise a few times a month IMO. There is however room for improvement on prop / motor combo. Ideally I would run a 34" prop but would need a higher KV motor 105-115. Since you can't get those off the shelf you either need to rewind motor, pay a lot to get custom made, or go with 100kv. I think the ideal prop with a 100kv motor will be around 37x16 with a target goal of pulling 195 amps. The carbon props I'm using are a VTOL design so they have a bigger chord near the hub then a traditional airplane prop though much less than a drone. Since I've open sourced design files it would be great if others can test props and share data.
Thanks. Also appreciate you posting videos of your build. I'm working on a 2nd version of the ehelp which will be drastically improved. The twin glider mount unit is also working really well and should have an updated version in the spring as well.
@@cwallen32 Thanks Charles. My bad for not looking down that far.. Built one of those E-PPG's from open source. Just never got cool with the paraglider thing and looking to come back to HG with the e-benefits. These files will really help.
We’ve met and flown together at theECC HG meets. I’m presently working on my tween motor design mount that’s located much different from yours. How can I get in touch with you? Nick Caci
That is a beautiful design, well done. I have a wireless e-winch I have built. Your mouth throttle would work perfectly with it as it is also Arduino controlled. Would you be prepared to sell me a complete mouth throttle unit, or provide a complete bill of materials so that I can get one made locally?
I've open sourced all the design files including fusion 360 CAD files and the STL in case you just want to print. The BOM has all links to all the parts. I may be open to printing the mouth throttle parts but don't really have the time to assemble, solder together etc. PM me to discuss, I may also have some of the spare parts as well.
@@cwallen32 Thanks for the reply. I did download the files but I completely missed the bill of materials. I'm sure I can find someone local to print the case for me and I have ordered the sliding potentiometer from a local supplier. Thanks again and fly safe.
@@hangflyer Did you find BOM? Also Fusion 360 is free, so you can tweak design if needed. I probably did 20 iterations of mouth throttle to get a perfect fit for my bite which may be different for others. I also had to tweak to fit in full face helmet.
Ender 3 should be fine. I believe it has an all metal hotend. I printed some parts in Polymaker PC Max (PC/ABS) which needs a heated enclosure however you could do everything in ABS or ASA. I would suggest ASA as its doesn't warp as much as ABS and is UV resistant. What's really important is print orientation, # of perimeters, and infill. I'll add some print settings to the open source files.
Yes. Have a fireproof protector around harness main line. Also parachute line does not go up main line to carabiner, its connected internally to the harness. In the revised version I plan to have the batteries on rails and spring loaded with a burn string that would allow batteries to be auto ejected if they flame up.
Very cool. What altitude/flying weight are you operating at?, I am 90kg flying out of Northern Utah (5000 ft), def looking towards a geared system for higher thrust.
I hook in at about 200lbs with harness, chute, ehelp etc. Taking off from sea level. I wouldn't go with a geared electric system, makes no sense. For more thrust i would move to a bigger motor / esc / prop / battery combo. I already purchased a Mad M30 and APD 240amp esc. This can also support 2x 7s batteries. I plan to increase prop diameter by putting in a custom folding hub which would increase diameter by at least 2 inches. Also at higher altitude air is less dense you need to think about increasing prop pitch, not spinning it faster.
@@cwallen32 I'd like to get the equivalent performance of a Hidden Mountain X1 (Vitto 100Evo 18 hp, 1.4m prop) out of an electric system... so a lighter/home-built version of the German e-lift system. Thanks for sharing your work!. PS. Trying to look at your shared files, and unable to download.
@@romeromf i'll check my server and see why it isnt working. I wouldnt go with a 1.4m prop, way too big, you can go smaller and spin faster. The elift is old tech at least motor esc. You can get a cusome kv motor from MAD and the APD escs are really nice. Prop selection however is very limited if you want CF, and just slightly better in wood. I'm getting 400fpm on take off going down to 200-300fpm over rest of flight.
@@cwallen32 and the e-lift is 13,000 Euro too.... 400 fpm at SL will be marginal at 5000ft launch and operating at 7-8000ft at 260lbs hook in weight (210lb pilot+20lb harness+30lb min e-help)... working the numbers to size the system for this scenario (3H.. high-hot-heavy).
@@romeromf I'm using the M20 setup and moving to an M30. Based on your weight and altitude I would go with an M40 or M50 setup. M50 seems to be overkill. This will also force you to a 100v setup and require 4 6s batteries so weight is going up by 50% if not more. Below is what I would buy, whole setup will be $4-5k.

You can make one. I open-sourced all the design files (link now works). I also created a FB group so others interested can share their designs and experiences. Both links are in the description.
Thanks for sharing, very interesting. Amazing how simple the setup seems to be.
Excellent work. Please keep sharing your progress!
Impressive ! Very good build !
Fantastic Job!!!! :)
This is a great idea. I would be super interested in the 3d files and the source for the arduino.
I open sourced all the Fusion 360 files and the Arduino source code. I'm also open to sell the one you see in the video. I plan to make some upgrades over the winter and would rather sell this one than cannibalize it for parts. PM me if interested.
Also better flight video here: ua-cam.com/video/2QEa9IL_ZlM/v-deo.html
Very cool! Whoever filmed the flying though....lol!
Ha, was lucky to get flight filmed at all. Have a bunch more flights but not on film.
Judging by the noise, I wonder if the prop design/pitch etc could do with some tweaking to get more thrust and less neighbour annoying noise?

Charles got the kv motor make and propeller diameter and pitch for my database?
Hi. Thanks for sharing. Am really interested in aspects of the project. Where are the files hosted
I have them on my NAS and shared the folder. Link is in the description. Let me know if you can't access.

Tell me that I could get a folding prop for this.
I think i open sourced the design files for a CF folding prop.
keen to build this, would a creality ender 3 pro 3D printer be suitable for this task? thanks

How much would you want for it, no harness just carbon e help
I open sourced all the files so you can make. I may be open to sell at the end of the flying season but would be much cheaper to make. PM to discuss.
Concerns about heat or battery flair up effecting your main support? melt through? Did you put a protector around your main support?
Yes. Have a fireproof protector around harness main line. Also parachute line does not go up main line to carabiner, its connected internally to the harness. In the revised version I plan to have the batteries on rails and spring loaded with a burn string that would allow batteries to be auto ejected if they flame up.
@@cwallen32 Ive been looking at this myself and have been studying the E-Help on youtube..
@@Highrockman I opened sourced all the files so should be easier to make then the ehelp.
