Great!!! Why not to open mold?
Am I correct that I need two of the feather boards ? One as a Rx and one as Tx
For now, yes, but it looks like he’s testing a cheaper alternative with a nano + transceiver module.
Yes, also just got these TTGO LoRa32 modules, $15 including the same OLED screen:

I think they ll be an perfect alternativ part for the expensive Feathers… but probably not the LoRa version. Is there a normal HCW Version available?
Just tested the transmission speed, it was around 100 ms in default mode but dropped to 11ms after setting this modem configuration:
Bw500Cr45Sf128: Bw = 500 kHz, Cr = 4/5, Sf = 128chips/symbol, CRC on. Fast+short range.
Not as good as RF69 (2 ms), but still ok. The SX1276 chip itself supports faster FSK modulation, but it’s not supported yet by RadioHead library. I’ll build a new remote with this board and test it in real life conditions next week.
Big thanks to @Fabialbo for recommending this board.

Build in an counter for failed transmission ect. Would be interesting how stable the connection is…
I have an debug screen where I show RSSI, longest cycle time since remote switched on and how many lost transmissions. That’s the best way how to check stability in real world.

Here I count a few data on extra sites…
This one is just real-time data.
-RSSI
-transmission and receive time for ALL data
-TOTAL cycle Time
-Maximum Cycle Time including failed transmissions
-failed transmissions
-Cycle time

I’ve updated stl files and the parts list with the same switch as in Firefly remote. Also added a small nib as an option. No need to re-print the bottom part, just fix the switch in the new location with some hot glue.

I already bought the extended lever switches but I’ll just snip it off, thanks for the nib! 
Standard lever switch from mouser for anyone who needs it

I don’t know what u mean when u say they are hard to find… just search for „Mirco Switch“ u ll find tons of these on eBay…
i meant the long lever arm version was hard to find. Standard arm is a dime a dozen.

Ahhhh ok, now I understand 
Where can I find th anntena that’s noted in the parts list
You can just solder a piece of wire to the antenna pinout. If you want a bigger antenna, you can solder this to it instead https://www.adafruit.com/product/1661 and get a larger antenna for it
Wonder if this would work , I’ve got these from FPV flying lying around https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwjnqe6_ur7eAhUJiH4KHfUoB3YYABAbGgJwYw&ohost=www.google.com&cid=CAESQOD2K_l19ooxss5pv6QpXV70XFCedS_izves56it0xRDQeUkwK0KWxkiDhzwH5jhTvBi2oeHAWvhe8bZm3UB9WQ&sig=AOD64_3muXtnCkCjtO1L4_syJ6Y3En-bMQ&ctype=5&q=&ved=0ahUKEwjVmue_ur7eAhWDHTQIHbc5D9wQwg8IKw&adurl=
Sure, both Feather and TTGO boards operate on 915 Mhz.
Hi everyone I have a question love the remote I use I just want to know if is possible for me to just add a screen for see the battery % and my speed and maybe the distance Some one can help me thank you
What material is recommended for the 3d prints
