Universal Ballast Kit
A universal ballast kit for all of our aircraft. This kit allows up to 13.5 ounces of ballast, within a 12″ brass outer tube, using (11) 1″ molded lead slugs. Also included are 7 wooden dowel spacers to allow a range of 4-11 slugs; both 1/16″ & 1/8″ balsa sheeting (for use with different planes and/or airfoil thicknesses), molded plastic end caps, installation instructions, etc.
This is an “End-Loaded” system, and does not require Dremel-notching an access bay in the brass. Rather, a small access cavity is routered in the wing, at one end of the tube, and utilized to load and unload ballast, via one of the provided end caps. For flight, the cavity is filled with a small piece of balsa, hardwood or foam plug (not included), and taped over to keep everything snug.
This kit will fit the Moth, HP60, and M60, as well as many other, non-NCFM kits. For the 48″ Halfpipe, the outer tube would need be cut down to 9″, using 8 slugs, though it is not really necessary, or recommended, for that particular plane.
Each Ballast Kit Includes:
• One 17/32 O.D. X 12″ Brass Outer Tube @ 1oz +/-
• Eleven 1″ Lead Slugs @ 35grams each
• Seven 1″ Wooden Dowel Spacers
• Two Molded Plastic End Caps
• Balsa Sheeting Cap Material (1/16″ x 1 ” x 12″) + (1/8″ x 1 ” x 12″)
• Installation Instructions
