The seller Hi,this f540 brushless motor is 4 poles

Nincompoop The conventional layout of T-tail is more stable, and the structure of v-tail is simpler and more flexible.

svetoch_ if you take jp4in1

The seller no

BG204249554 little but they are still strong enough

Daisy No

Septimal Can not find Eachine EO16CH on BG Website, so can not make sure what procotol is it. iF8 support D8 / D16 v1 FCC / D16 v1 LBT / D16 v2 FCC / D16 v2 LBT (No Frsky ACCESS support) . You can check by yourself.

heli7 yes. you can cut it

Hoydenism No,you should buy this one drive shaft,product id is 1318141

CutiePie not sure

Winnit No, the Vista will not fit into this frame.

Povd It is just a piece of wire but that is typical with any whoop board with a built in reciever and I'm sure it has something to do with them being synonyms for having horrible reception, that being said the antenna dosen't need to be grounded to work correctly. When you run ground to a receiver wire it's to ground the shielding on that wire and then the actual signal wire runs through the shielding till it getd close to the end where its exposed and this exposed wire at the end is what actually dose the work cause its cut to a certain length to work with the particular frequency being used 2.4ghz in this case. As long as that wire is the same length as the wire that exposed from the shielding on a wire that's has to be grounded it essentially dose the same job. but it also has to be free from obstructions cuase that can dramatically reduce your range so this is where longer shielded wires that have to be grounded are preferred if weight isn't an issue because they move the signal wire farther away from the obstructions of the frame and other parts on a model
