AMA Indoor Free Flight National Records Listing
Because there are often errors in the published record listing on the AMA website as well as long delays in processing record applications, I will now publish an updated list the same day I approve AMA record applications. This webpage will then have the most up to date published AMA National records list. Each ceiling height category has been condensed into a single sided single page page PDF. As I update a records list, the date of the update will be shown below.


Category  I    (last updated 4/29/2025)
Category  II   (last updated 5/26/2026)
Category  III  (last updated 7/17/2026)
Category  IV   (last updated 7/22/2025)

Model Plans and Miscellaneous:

"Scraps" Plan
 (flat wingspan is 214mm)

Jetco ROG one design for the 2024 Midewest Indoor Championships

Zig Zag Calulator Spreadsheet for cutting tapered spars with a Harlan style cutter.
See May 2019 issue of Model Aviation

EZ-A6 3-View
EZ-A6 full size wing and stab plan page 1 page 2 (print 100%, wing chord is 2.25" and flat span 13.88")
I designed this for my son to set the Jr AMA record in A-6 and F1L class in 2012
I would use a lower prop angle, about 40° instead of 45° as the higher pitch is too much at the end of the flight.
