LiPo -2  Battery Section Construction & supports

LiPo Battery Section of fuselage
- Part 2  

    Battery Compartment View - holds up to Three 5000 mAH LiPoís
    At about 3 pounds of weight, the three LiPo batteries offer much power but this gain is offset by having to carry that weight to altitude. Below are some details and photographs covering the revised compartment.

  Open top of fuselage with cut using dremel carbon wheel. Then, remove two steel (elevator and rudder) rods connected  to Vee Tail.

 Cut two 1.25 inch wide by 1/8 inch thin plywood stips and hot glued them to 0.5 inch aluminum angle to support the L shape wood strips. Invert the wood stips and cover them with foam material.

 Hot glue new A frame plywood strips down center of fuselage. Glue both sides to vertical support and glue along both sides of strips.  Add center wood right angle inverted support padded with foam glued to wood to support LiPo batteries - max 3 batteries.

  Epoxy aluminum thin flat to center plywood vertical support.  Hold both together with red C-Clamp until fully set, about 24 hours. Drill small hole in Aluminum flat to slide pin to support LiPo batteries.

   By placing the LiPo battery compartment slightly forward the designed wing center of gravity results in a more stable aircraft with minimal structural requirements.  

     A maximum of three LiPo batteries (almost a pound each) may be housed in this space resting on both the 45 degree walls and center support. 

     The resulting free space in the nose by removing the two standard size servos are relocating them to the tail and the new LiPo battery compartment means almost the entire nose is available for electronics, sensors and cameras.

   Epoxy or glue (Plumbersí goop) new 3/4 inch L angle by 1/2 inch wide aluminum clip to side of where LiPo battery rests against floor - see (center left side of battery) compartment. Two batteries shown here.

   Slide bent steel wire nose (sect. one) into hole drilled through flat vertical aluminum plate of Nose section into into black carbon fiber tube pressing aluminum L square corner over (blue) LiPo batteries (section two). Then, roll wire into servo screw-in hole of plywood to the left side.

   Two thin carbon fiber rods - shown above - connect the nose (section 1) to the landing gear (section 3).  Both ends secured by clear Plumberís Goop.

   Above left the brass plated closed hook remains sector.  Next step: build out the fiberglas LiPo battery housing.
