gk1975 Don‘t know - but there are many vendors selling it

gk1975 I‘m using the 4s version, which works nice

gk1975 Hi! You certainly can - that‘s what I do with it. But you will need multiple passes

gk1975 This is not ELRS - it is MPM. eachine should work with it.

gk1975 Bootloader was installed on mine - but also available on GitHub

gk1975 Single speed

gk1975 What‘s your plan? PWM is okay, pulse width can be set. (0-100 about 1500 msec, no -100 to 100, firmware would only allow „forward“ on a plane ESC, if you need both rotational directions, you‘ll need a car ESC, this is airplane) This normally plugs into an RC Receiver and needs to power receiver and servo - so the ESC includes a BEC (will OUTput 5V to receiver or controller from battery, can your controller take that?) You might need an Opto ESC (no BEC power supply to receiver) or cut the negative wire of the servo connector to be save.

gk1975 Yes, it supports ACCST protocol. Might need a firmware flash on Module and RX. If you just want to use R9 you will be better off (easier) to get a FRSKY module, this will be easier and maybe even cheaper

gk1975 There seem to be lots of people using that

gk1975 Github - search for multiprotocolmodule

gk1975 Flight time depends on the battery you put in, range depends on the radio link you use - this is just the plane

gk1975 Depends on used protocol - whatever the protocol allows. 16 typically

gk1975 Adjustable low batt cutoff, yes. Safety cutoff is set from tx (arm switch), not the ESC

gk1975 They have lock nuts - so it doesn‘t matter

gk1975 Depends on which kit you order - there are several options. Just look at the pics. This is a kit - if you want a plane ready to fly for beginners - better look elsewhere
