The removable front canopy allows for streamlining the Talon when a pan/tilt setup is not used. An optional nose without the camera is included as well
Shown above: One of the fuselage pieces highlighting the flat floor as well as integrated battery strap slot. The floor also has hard mounting points built in (put threaded inserts in them) to mount electronics and other components
The hinged hatch will now stay open on its own since it can rotate up to 105 degrees, allowing for easier battery insertion and access to internal components
The optional airspeed sensor mounting is simple, low drag, and lightweight. The bottom half of the housing must be glued to the fuselage, while the top half can be screwed on. The housing fits both the pitot tube as well as the sensor PCB, allowing for a non-permanent install with only wires exiting the housing and no tubes
Materials
Print using prefoamed LWPLA (this one) and you will need the following parts:
(2) 8x1000mm hollow (6mm ID) carbon tubes (main wing spars)
(4) 3x400mm carbon rods (aileron hinge and wingtip support)
(4) 2x220mm carbon rods (taileron hinge and vtail)
A bunch of m3 threaded inserts <= 6mm in height
Recommend using Emax es08maii servos for wire clearance
6x3mm magnets for the canopy
Medium CA glue
Polycarbonate or other high-temp filament for the motor mount
220x220x250 minimum size print bed (Ender 3)
Tips & Tricks
Recommended electronics:
Video: RMRC or Matek 1.2ghz VTX - or 5.8 analog/digital
Control link: Dragonlink / TBS crossfire / ELRS
Motor: 4108 620kv or similar
Prop: 12x10 or 13x8 or similar folding props
Battery: 4S6P 21000mah or similar
Flight controller running Ardupilot (such as Matek F405-WTE)
Matek M8Q-5883 GPS
Blheli 35a ESC (lighter the better)
19x19 FPV camera (digital or analog)
Emax ES08maii servos (for wire clearance)
Print settings:
Single wall
4 top/bottom layers
0.3mm layer height
3% cubic subdivision infill
Avoid warping by using a glass bed + glue stick or PEI sheet
NO supports needed!
Set horizontal hole expansion setting correctly (try 0.25) for spar fitment
Print the motor mount in Polycarbonate or PETG with 2 walls and 15% infill
Other recommendations:
Configure flaperons (they work great)
Apply 1-2mm of reflex (up elevator) for best stability
Autotune or bump PIDs significantly for snappy performance
Aim for an AUW between 1.5kg and 3kg
Aim for CG as close to the wing marking as possible
Give it a nice run up + hard throw into the wind on launch
Reinforcement:
Apply rubberized tape / duct tape to the bottom of the fuselage for protection against harsh landings
Use a rubberized strap (in the slots in the fuselage) + velcro for securing the battery
Apply epoxy to the motor mount area to prevent prop snag damage during landing
