Introduction - Phantom FX-61 Number 2

On this new build I have decided to go a lighter weight route and a swoopier (smoother) airframe in terms of add-ons like antennas, VTx's cameras etc. On the lighter side I am going to use a Cobra 2814/16-1050kv motor and an 4S/5200 Multistar (442g) or one of my 8 cell Panasonic 4S2P packs (405g). I am also going to try the Corona CS939MG 12.5g/2.5kg servos because I can't currently get Hitec HS-82MG so this also saves me about 12g as well. These three things plus not using a GoPro in its case are collectively 564g lighter than what I was flying on my first FX. AUW should then be close to 1600g which should make for an easy flyer!

On the swoopy side I am going to put the DL 433 dipole in one of the vertical stabilizers and let the lower element flop in the breeze. I have done this (flop in the breeze) on my MiniTalon and the range is still much more than I need. I will also print up a cover for the Mobius and FPV cam.

I will keep the servos on the bottom of the wing and use a servo arm cover to keep it safe from landings. I will use a limited amount of 3 mil laminate on the leading edge, wing tips and wing roots. I might add some monokote to the bottom to cover the spar and other gaps. I will print covers for the thumb/finger cutouts and the downward camera hole. All of this will make it much more slippery and lighter which will add to the flight time.

Wings

I started with the wings (again). The first task was to glue on the 0.5mm X 3mm CF strips on the trailing edge of the Elevons.

I then printed up some mount pieces to be inlaid into the elevon foam for the purpose of making a stiff, solid mount for the control horn. Using a soldering iron with a flat tip I scoured out just enough foam to lay in the two pieces so they are perfectly flush with the top and bottom of the control surface.

I then made up a pair of carbon fiber control rods and assembled it on the wing to get the length sizing correct. I also printed the servo covers which will be inlaid after the servo is completely set-up and glued in.
