Before you order - CLICK HERE for shipping schedule & product availability. Plan ahead -  These projects cannot be completed successfully in haste. Allow enough time for shipping, transit times , and careful construction and testing. We do our best ship orders which specify 1- or 2-day delivery on the say we receive them, but we do not guarantee it.  


Enhance the competitive value of your endurance indoor model with modified motor stick (1/4" sq or 3/16 x 1/4)) and tailboom (1/8" sq). Taper where possible for better efficiency. Buy 1/16" sq sticks for extra spars for wing, stab, fin, etc. Sticks can be sanded lightly if needed to reduce weight.

 The supplies needed for competitive ELEVATED BRIDGE BUILDING building events are few and straightforward. Balsa, with its high strength to weight ratio, is the wood of choice. All substructures must be made up of strips no larger than .25" x .25" (cross-section), which makes wood purchase simple.  Any width or thickness of substructures laminated from this basic component is permitted. Wood may be sanded to reduce thickness where needed for optimal strength/weight distribution. 
Tip: glue is much more dense than balsa, so extensive laminations may be disproportionately heavy. 
Tip: Balsa varies considerably in its density, i.e., weight per unit of cubic measure. Each piece should be weighed to determine its suitability in a particular part of your structure. 
Heavier = denser = stronger.  Use the heavier pieces in areas requiring the most strength.
NOTE: there is no reason to use species other than balsa, which has the highest strength/weight ratio. We now have .01g resolution scales to make this task easier.

BALSA -    

We now offer three grades of Balsa:
1) Medium Density Balsa unselected: 10-19 pounds/cu.ft
Range of densities expected in any sufficiently large random sample is 10-19 pcf, with usual expected outliers. Distribution is a fairly broad normal curve with average near center of range. Piece-weight is calculated by dividing sheet weight by number of sticks/sheet. Not individually weighed. 
2) High Density: mean density 21 pounds/cu.ft, nominal range 19 - 24 pcf
Range of densities expected in any sufficiently large random sample is 19-28 pcf. Distribution is a tight normal curve (small variance) sharply skewed to low end of range, with average = 21 pcf. 
Pieces are individually weighed.  Higher weight and strength, greater stiffness. 
3) Low Density: mean density 8 pcf;  nominal range 6-10 pounds/cu.ft
Range of densities expected in any sufficiently large random sample is 6-10 pcf. Distribution is a tight normal curve (small variance) with average = approximately 8 pcf. 
Pieces are individually weighed.  Light weight, less stiffness.
