So for your FPV rig-
Before gluing halves together trim out the battery bay so a 3s 5000mah battery will fit. Use their glue to mate fues halves together. Just use it. It's not bad glue. the best part is it softens with the hot water and can be pulled off when the nose needs to get back into shape after it crashes into the ground, then CA can be used after the repair.
Look for a dent in the tail boom on the right side AFT where the tail wheel rod connects to the rudder pushrod, install servo there; trim and z bend rod to fit servo's new location. Install elevator on other side to match to get the CG right for the 5000mah battery. Run the servo leads in the pushrod channels, then poke holes so the leads enter the fuselage at the rear of the cavity. Wrap leads from this point in packing tape, then copper foil tape along with the ESC and battery cable. Don't to forget to install the current sensor at this point (Powerpack C needs this extra length so the battery can be plugged and unplugged easier) ground copper, then cover with another layer of packing tape. Install raspberry pi with Navio+.
Install cameras and Vtx on the tray with antenna aft (use 90 degree elbow to point cloverleaf up), or just skip the tray and 3D print a FPV canopy with pan and tilt off, see thingiverse.

Take the propeller that came with it and tape it to an expoxy kit. You will have a nice stir stick the next time you need to mix epoxy. Get an APC 10/7E and place a prop balancer hub to get a center, then use a compass to measure the distance from the motor shaft to the tail boom. Mark measurement on new prop, then cut access off, sand to balance.
I can get a 30min flight with a 10 min reserve.
Everything else is clearly (?) explained in the instruction manual.
Best of luck,
Justin
