Hello everyone,
wanted to share my mod of Flipsky VX4 pro remote.
In short: I made a new case & drowned the electronics into Plastidip to make it waterproof. Added some foam to make it float. Works great, sender/receiver seem to be strong, even when the remote is quite deep under water. And I really like the display. Haven’t tested it in salt water yet, but I don’t see a problem as long as everything is rinsed afterwards.
I actually made a first test with the old VX4 and had to replace the trigger with a magnet switch - works too, but the pro version makes it easier, because they already replaced the mechanical with a contactless trigger. So if you want to try this, be sure to get a VX4 pro (bought it on Aliexpress for under 60 Euros), not the old one.
For charging (and eventually updating firmware) I have added a magnet USB connector that plugs into the USB-C of the remote. The pro-version has 4 buttons (instead of 2 of the old version), but I only use the lower 3 and ignore the upper one in my mod. I have used Tinkercad to design the case - my 3d drawing skills are limited and so is Tinkercad. Anyway, I have made the trigger coming out on both sides so I can use both thumb and index finger and made the lower part extra-thick, because I tend to push the remote on the board to get up. It is surely not perfect, but it works!
What it needs:
- a can of Plastidip (or similar) to sink the electronics in completely
- 3 stainless steel screws (for wood or self-drilling), approx. 2x12 mm
- a USB-to-magnet adapter
- some packaging foam to make it float
- a 3D-printer of course
- open the original remote, there is a screw behind the sticker, it needs some careful force, 4 more screws hold the board inside
- remove the (not used) 3M glue strip from the battery, carefully clip out the 3-button-thing from the left shell
- plug the USB-magnet-adapter into the USB-C
- drown the whole thing including display, USB and battery (but not the top moving part of the trigger!) into clear Plastidip, let it dry at least 24 hours, then look carefully that everything is coated, if not, apply some more Plastidip and let it dry again
- turn it on, drown it into water: if it turns off, dry it & check for leaks again
- remove coat from the top most of the magnet-USB (just a circle) so a charging cable will be able to connect, be sure to leave everything else coated
- print the case & trigger
- fill the open spaces of the right shell with foam to make the whole thing float - I had to try quite a few (packaging foam from the rubbish), most of them worked but drowned after an hour, be sure to use some very light weight “closed foam”
- place the printed trigger over the original, put everything into the shells, drill in the screws, attach the lanyard: there you go!
STL are here.
