FM800PRO RX is a reciever for Futaba transmitter. You can use DSMX Reciever. The FC has pads to connect DSMX RX.

you can use betaflight configurator to flash firmware on your controller.

Dear AeroNishi,

can you show how exactly you have setup your FC? Did you use any template?

thank you

Hi David,
I used flying wing templete with differential thrust setting in betaflight. In inverted flight, it is still experimental, but I used 3D mode, bidirectional ESC setting and slightly modified betaflight source code.

Thank you Nishi, I am going to start experimenting with this and probably we will release EPP jet with exactly this way of propulsion. Thinking about JAS Gripen.

in what way? would you not be happy with non-modified BF source code for this purpose?

To stabilize the aircraft in inverted hovering, it is necessary to reverse both rudder and elevator. When reversing motors in betaflight 3D mode, rudder will be reversed but elevator won't. That's why I modified the code. Since Betaflight is an open source software, one can access the source code.

David,
In normal flight, non-modified BF or iNav is just fine for the purpose. I am looking forward to your EPP jet!

Have you any video of changing the thrust direction during flight?

Sorry but I don't have such videos.

is it possible to transition in flight with your systems?
