Down to the last wire to run for canopy closing. Last job will be final weights and balance where Retract and light batteries will be finally positioned

Spent most of today on customer Simon’s Mig set up. JetCat P-220Rxi and Powerbox SR2 with ISat Gyro. MacGregor servos-he uses Futaba hence most of day to do the set up!
Paperwork to do and it’s ready to fly.

Thought about this for a while and decided I didn’t want a loose lead to plug in for the hatch/canopy opening.
Powerbox 1132 One4One connector auto plugs it in.

Maybe the 235 is shorter? It’s only the fittings.
I have magnets too under the flanges. Mixed thought on them being strong enough. We will see!
Travel stand for my short wheel base van. The rear fuselage plugs into four 20mm carbon pegs. Few more details to add.
It will also carry the wing tubes, pitot tubes and aerials.

Then I'm lucky to maiden after you .....
What diameter are your magnets ? Mine are 7mm. Using 3 pairs.

6mm. I thought about one on the face too, but they are weak in shear. I can go to 4. Just wanted to see I could still open it first 😄
I have the original steel pins to locate the hatch. My intention is to test fly with two strips of clear diamond tape over the joint line…with a slack loop over the joint. If the hatch lifts 2mm the tape will go tight and I should see it lifted, but not lose the hatch.
I’ll be your test mule 😉

I used the accurate string trapped between each wing method. I just don’t see undercarriage axles all being in the same position on every model where it’s a trailing link set up.
note all the fuel is just forward of the balance point, so I put 1ltr in the centre tank to balance my Mig.

Turbine test run done, just need paperwork and suitable weather/venue.
My stand idea failed…should have checked height before making all the parts! Working on the second idea…

David,
Whenever you have the time, please let me know the weight on the nose wheel once you are satisfied with the balance.
Did you abandon the magnets idea for holding the front hatch ?
Hope the maiden goes uneventful.

No I still have the two magnets. I have kept the CARF vertical wire pins, even just those the hatch would stay in position while the fuselage was rolled over.
I’m convinced the Magnets will be fine.
I have positioned everything based on CARF’s balance being too safe. I added 85g of removable weight in the nose that I expect to remove after the first flight. Will give you a nose weight when I can fly it. No paperwork yet and anyway I’m off to do a UAS flight test for three days.
