Question:

Mr. Richwine,
You deleted the specs for the gearbox blanket off the tech page. For example: How many layers of Kevlar or nylon? Minimum width. etc... Can you please provide or put back on the tech page?

Thanks

Answer:

Page 22 of the 2009 NTPA rulebook reads:

Any gearbox less than minimum specified thickness may add a steel strap radially 360 degrees and fastened within 1/8" of gear box to achieve minimum total thickness of gear box. After achieving the minimum thickness the following blanket must be used:

8. A blanket must wrap 360 degrees around the circumference of the crossbox or multi-engine gear box. The blanket must be 20 layers of Ballistic nylon or 15 layers of Kevlar with straps that wrap around the entire gearbox at least every ten inches.
