Scorpion 25 x 30 bolt pattern
Would someone with a Scorpion motor with the 25 x 30 mm bolt pattern in their e-Aurora mind posting some pics of how they routed the motor wires. I would like to change the motor in my e-Aurora to one which uses the 25 x 30 mm bolt pattern but would like to see how this will affect the routing options for the motor wires.

Thanks.

Hi Grazer

I had modified the motor mount last spring to accept 4mm screws on 25mm pattern to accept the HKIII 4035-530KV motor and still have nice looking Aurora with the motor wires running inside the frame.

I drilled the 25mm spacing 3mm holes to accept the 4mm screws and use 4mm spacers to fill up the gap and file them down so they are flushed with the surface of the motor mount, so the screws will have good support when you tighten them. Just make sure the screws are not too long causing shortage.

pics for your reference.

Here are some old pics I stumbled upon with the older style frames.

Wires are run directly down the middle of the frame, to the ESC. Motor was a HK4035-500

Thanks for the pictures guys. rappyfly, what you have done is exactly what I have been thinking as I really don't want to have to deal with the motor wires sitting at 45deg to the frame and would prefer to have them run in the frame.

Hi Grazer,

would you mind taking some step by step of the 4mm mod on 25mm spacing..

I would like to see how it's done.. especially the spacer to fill the gap.. i didn't quite understand that part..

I'm having my sticking out of the frame.. I'm running the HKIII 4035-530..

thanks

Hi Remote

The 4mm screw head is bigger than the recess for the 3mm screws, so you don't want the pressure against the screw head and the ridge of the recess. If my memory is corrected, I used old NHP blade inserts as spacers.

Hi remote

The spacer is inside the hole for the 3mm screw head.

With regards to Scorpion motors in the e-Aurora...

I have used both the Scorpion 4035 motor (which uses the 4-bolt portion of the Aurora motor mount) and the Scorpion 4525 motor (which uses the 2-bolt portion of the motor mount). As long as you are using Loctite, then there is no need for washers. I simply put the screw into the recessed hole, and tightened it up.

The screw should go "inside" of the recessed hole in the aluminum motor mount and not across the top of the recessed hole (as some are suggesting). If the screw does not fit inside the recessed hole, then perhaps try a different screw with a slightly smaller head.

The most important thing to do is to make sure your screws are not so long that they touch the windings on the motor.

Thanks Justin,

Any suggestion on how to drill the hole without messing up..

I don't have a drill.. do you think a dremel would be good enough..

cheers

i am currently running a hkIII 4035 500 in my avant and only using the 2 hole spacing for the bolts. Its the only way it would line up with the motor mounts and it works perfect. i was under the impression that its alright to only you 2 bolts to fasten the motor to the mount.

As the topic says.. to use the 4 3mm hole so the motor wire is inside the body.. as it is now.. its sticking out from the body by the side when you mount the 4mm hole with the New HKIII 4035-530..

I'm glad to hear that it's ok to mount just the 2 4mm hole.. just that the wire stick out by the side and the motor wire is folded uncomfortably bt the body C.F.

so I'm contemplating to drill the 3mm hole to 4mm.. so that the motor wire can be hidden in the body..

You can drill little holes through the CF and pass zip-ties to hold the wires. But better yet is to pass zip-ties through the existing holes. There are quite a few holes in the frame with which to pass zip-ties through.Avant RC
