I can't get the fc mounts to stay on, they've snapped off the original base, the second one and now this latest one, I can't trust them at all now so I've drilled through, will countersunk them and bolt through the base for a secure fitting.

Started putting the arms on, not happy with the ball plungers, the arms are still very easy to move, I was assuming they would/should snap the arms into place. It might be the locating hole on the arm is too small but ill need to look up the specs of the plungers to check that.
I'm not sure of the solution, the whole spring thing that most others do isnt what I'm after either really. I'm thinking the way to go is to have pin plunger that goes into a hole that has a pin hole on the outside so the only way for it to fold back is to insert somthing like a SIM card removal tool from the outside to pop the pin back in.

Unfortunatley there's somthing wrong on my arms, when folded they hit the base and if folded fully are actually being forced outwards and straining the mounting point, either the angle on the base is slightly off or the angle on the arms. It could be different when it's together so I'll wait to see how far they need to fold then, it may be a good feature to have cap heads on the front mounts instead of the countersunk I'm using, it stops the arms going to high.
To save re drawing then reprinting either part I'm going to file the present arms down to fit properly once it's all together if needbe.

I've used countersunk bolts for a cleaner build.

nice Kananga. I just got my parts. Unfortunately the props can't be mount onto the motors... Do you see anywhere which wire is which one on the motors?
need to widen the holes for the motors a bit. otherwise the screws won't fit.

the sonar however, fits perfectly and the 4-in-1 ESC olso perfectly on top of the flight controller. will try to start mounting some in the next days / weeks.

Wires don't matter on the motors, the escs will sort it out, the motors are tight on the arms but i thought they looked like they would fit I'm printing a new base as i type so tonight I'm hoping to start putting it together (again lol) so I'll be trying to mount the motors tonight.
I haven't checked the props but I assumed the holes were wrong as everyone alters them. I'll check them out later as well. There are various files for adaptors but I need to check out what were looking at.

I'mfitting the motors now, and they fit well on the arm. Just need to widen the screw head holes on the arms so the screws can fit.

and watch out for de names of the motors: CW and CCW are the screw head threads, not the direction of the motors!

Got the latest version of the base printed out, I need to clean the bits of slurry off it but it's looking good, I'm happy with it.

I've had a look at the props, I know there's adapters you can print or the existing ones could be drilled out but it would have to be accurate.
I'm going to have a look on thingiverse at what others have designed  but I'm tempted to go 1 of 2 other ways open to me, I can either machine new adapters that replace the originals. I'll remove the props and attach them to the new adaptors or I could remove the motor can and machine the end down to fit the adapters. Although that means new props just go straight on I'm not sure I've got any left hand taps or dies the right size.
The more I think about it as I write, I think I'll machine some replacement alloy adaptors if there's nothing suitable on thingiverse although im not a fan of relying on fast spinning printed parts if there's a proven design out there already it would be silly to not at least try it. I print in abs at 100% anyway so as long as the pivot points are strong, accurate and balanced it's the easiest route.

The motors have arrows on the side, that's the direction they should spin in. The prop nut should tighten in the opposite direction to those arrows. The motors will spin in the direction according to your wiring, you can either swap 2 wires over to change direction or the easiest way is to do it in cleanflight or whatever program you use.

I've had a look and theres not much on thingiverse. There is a design on there done in a simular way to how I would do it but I think it can be refined for the racerstar motors.

I'm going to draw somthing up and see how it prints.

In fact we would need the opposite adapter of these in the picture, or the prop in the picture...

Or adapt these adaptors to fit the threaded 6mm shaft...

It would be great to use the quick release versions but personally I don't want the props that far away from the motors, I'm assuming there will be folding issues if they are too far away from the motor ends.

I'm not sure I follow your first post, my motors came with prop nuts so I don't need those and I've already got the props as you know so I'm not sure about your suggestion of needing more.

I'm going for somthing like this but for our 6mm shafts http://diyrc.co.uk/3rd-party-parts-12/mavic-prop-adapters-for-5mm-motor-axis/msg5212/#msg5212 I'm going to sink it down on to the shaft with flats so the props are lower.

Well, the holes of the props are too small to fit the 6mm shaft. So one can't put them on with the provided nuts...

No, you're misunderstanding me. Leave it with me, I'm going to draw and print an example this afternoon.

First version isn't quite right, I need to tweak the hole sizes but more importantly I didn't allow for the nut, lol noob error.
The solution is to drop the bottom part to the base of the can.
I will alter it later and reprint. I believe this is will be the solution I'm going to use. It seems strong enough and uses the original pins..
