Volantex Phoenix 2400 Long Range Battery Tray

Made to fit my 21700 4S2P Li-Ion battery, and utilise its dovetail to quickly mount it inside the fuselage. Flight time of that contraption is around 2 hours, and installation of battery takes a couple of seconds.

Upper tray has connection to the spar tubes - original holes in the fuselage don't take extra weight that well. In the rear there is a ziptie hole for mounting the receiver in less visible spot.

Lower tray gets glued to the bottom of the fuselage for better weight transfer of the battery. Low clearance requires the wheel to be removed and skid or smaller wheel to be installed instead.

Print in any reasonable material, ASA is recommended for low weight.

Assembly:

1. Apply generous amount of glue that bonds well with the fuselage (ABS plastic) to the Spar Stiffener and install it. Use Spar Tubes to set it in correct orientation, but be careful not to glue them in.
   

2. Drill 3 mm holes through the fuselage and Spar Stiffener right between spar holes.
   

3. Insert 2x M3 square nuts into the top tray and screw it in using 6x original self tapping screws and 2x M3x16 screws - use of large washers is advised.
   

4. Make a cut in the wings for clearance for the M3 screws.
   

5. Remove original wheel and install skid/smaller wheel.
   

6. Apply silicone or other flexible caulk/glue along the longer sides and the bottom of the lower tray and insert it into the fuselage. Use something heavy, preferably finished battery, to press both parts together.
   

7. Attach velcro as in the pictures, insert battery and have fun!
