After much consideration looks like I will be going with the Skywalker for my first UAV build.
Replacement Skywalker arrived today, 6 days from ordering to delivery, not bad. Building a second one is alot quicker and better than the first.
I found a few improvements in relation to putting it together based upon the end result of skywalker # 1:
1. Whilst the fuselage is in 2 pieces stick the velco tape along the inside for the RX and other equipment to be mounted, its much easier before the fuselage is one piece.
2. Cut out the side hatch with a brand new blade is easier than a not brand new blade and with the fuselage assembled
3. Use popsticks to mount metal name tag plates either side of the hatch, and hot glue magnets in the hatch.
4. Use popsticks inside the tail behind the leading edge and along the rudder to add rigidity to the tail
5. Test fit the fuselage halves before glueing and make sure there are no gaps in the join of the vertical stabilizer otherwise the horizontal stabilizer will not hold really firm and horizontal. Make sure the fuselage is straight and the horizontal stabilizer is horizontal and perpendicular to the fuselage.
6. After you glue the fuselage together use fibre tape along the seam to keep the halves together and it will strengthen the fuselage.
7. glue a magnet flush in front of the canopy retention screw, and cut a rebate in the canopy and mount a metal plate. I went to a name badge place and go some magnet fasteners and they work well.
8. Cut off all the control surfaces and join them back on with fibre tape on both sides running all the way along the surface
9. Fibre tape the whole bottom of the wing, from tip to where it meets the fuselage, as when the wing loads and wants to flex up, the fibre tape prevents the wing from over flexing or the foam from breaking loose from the carbon rods.
10. Fibre tape the leading edge of the wing.
11. Install velcro tape for the battery mounting so the battery doesn't go flying and change the CoG mid flight.
Get a metal detector and go find the DX-201, grid search a v pattern from first ground contact to 15 meters forward. I have found stuff just under grass or dirt that you will not see with your eyes, Good luck !
Attached files show found parts from UAS crash maybe for sale now.

I flew today in light winds, the OSD reported 60km/hr upwind and to 80km/hr downind.
My spektrum telemetry reported a top airspeed of 103 km/hr. Later that flight my left aileron was torn from the wing late downwind and I crashed.
Fuselage written off, Dx201 camera MIA, motor thrown from plane, wings undamaged except for the left aileron was found intact and attached only by the pushrod.
Lesson learnt, tape the ailerons to the wing. I had cut and taped all other control surfaces because they didnt move freely, but I just put two small pieces of tape on the ailerons and didnt fully tape them both sides for the whole length.
And I guess at 100km/hr they got ripped off the plane.
OSD doesnt show airspeed, but I set my DX8 to alert when airspeed exceeds 100km/hr, it did so on 5 occasions, the crash. I have landing gears on my SW with a castor tail wheel made it a bit tricky to take off straight. the left wheel came off on its first flight today and I landed on one wheel LoL.
About cruising speed:
It would be around 25-30 Km/t ground speed.
You are able to see speed and battery usage in this video.
