If you print it and find the dimensions aren't correct, I find it easier to change this in the slicing software (I use Cura) rather that going back to Fusion to edit it.

Hi Graham, I am also using Fusion360.
I'm still learning as I go.
I started by drawing a rectangle the size that I need and then extrude it into a cube.
Then draw an elipse on the top face and extrude away the bit you don't want, which gives you this:
Then I select the top edge and produce a fillet:
I then use the shell comand to hallow it out:
I then select the inside face of the flat end and extrude it away:
Hope that makes some sort of sense.

So, spent a couple of days tinkering with the battery tray and have come up with this:
First job was to remove the unwanted bit from the original tray
I then cut a new tray and added some 3d printed locking blocks.
Then cut some slots for the locking blocks to fit in.
I then added a back piece and some slotted tabs for fitting velcro straps.
I re-inforced these with some cocktail stick pegs.
The last thing was to make a locking catch.
More later...

Little bit more done:
I have CNC cut all the horns from epoxy sheet and installed them.
At this point I thought I would put everything together so I could weigh it before final painting and see how I am doing with the CofG.
The AUW with everything execpt the push rods is 4.6kg.
I can achieve the CofG with no added nose weight but the batteries need to be pushed well forward (a couple of inches beyond the battery tray. This is going to give me issues securing the batteries.
I need to do a bit of head scratching. Maybe split the canopy and make the back half removable, or perhaps some sort of sliding battery tray affair?

I made this, which is proving very useful. It clamps onto a tripod.

Fingers and everything else crossed.

That would be nice!

Here's hoping!

I'll have a go.

I'm in please.

Thanks Martin, the batteries are Zippy 1100's
As I had used red in the 'sauce' i was hoping that I would get away without having to use primer, as I am doing all I can to try and keep the weight down. The paint is B&Q Valspar that I had mixed and seems to cover quite well. I might have to do some tests.

I have been doing little bits here and there:
Glued one the side air intakes
Installed the LiFe batteries, lighting PCB and redundancy receiver as far forward as I could.
And added some detail to the cockpit.
Almost ready for painting I think.

I'd like to enter the draw please.

Please put my name into the hat.

These are new to me and prices seem very keen at the moment so I have taken a punt and ordered 4 x 4s 4000mah 55c batteries. They are labelled G+Plus - does anyone know if these are graphene batteries?
-
Very nice Steve.
I struggle to get my Provost in the air and would be interested in some details of your bungee device, is it home made?

I have a rule that I won't start a build until I have finished the one that I am working on otherwise I fear that I would never get anything finished.
I am nearing the end of my current Hawk build and the Mustang has jumped the queue and will be up next.

Me too

I have a spare Turnigy SK3 Aerodrive 5045/660kv that I am thinking of using on either 4 or 5 cells.
I am not sure if it will be too high a kv for the 14x8 four bladed prop.
Any thoughts anyone?

Regarding the FMS 4 bladed prop, am I correct in assuming it is the 14x8 version we will be using and not the 17x9?
