RCX 250 pro

Post by Lee »

Here is my latest mini.
It's going to be 4s, but while I'm waiting for the batteries, I stuck a set of 6040 dal props on it.
These will be cut down to 5040 bullnose, once the 4s arrive.

Here you go Graham.
I did have one issue with the PDB. The 12V out wouldn't let me run my FPV gear.
Couldn't get a picture.
Plugged it straight into a battery, and worked perfectly.
So i tried the pins ment for LEDs and it worked perfectly too. So I left them there.
Means I can switch my FPV gear on and off if i want :)

You can buy the PDB from banggood or myrcmart for about $10.
It has solder points for the Nase and the CC3D to directly mount to the board.

My pins go in towards the board, but are also underneath the board, instead of on top.

Thats what Haydn did to reduce the space in the Volt very clever idea:)

A few people have said the 12v is week for the vtx and cam normally if using a 12v cam, i have mine running from the 12v out to the vtx then that powers the cam at 5v and I have had not an issue,

Not sure what the XK is. MR Electronics man will tell you, I'm sure ;)
Mine is working perfectly since moving the VTX to the LED pins and not the 12V out pins.

Other way round Clay, BEC goes into the FC and the FC powers the RX.
