Film is a series of photos and clips showing the trimming process of the 37" span rubberpowered freeflight 1931 Babcock Taubman LC13, designed & built by Tom Hallman in 2019. Flying session took place in Wawayanda, NY on 7.3.19. Goes through a series of 10 trim flights, showing the effects of adjustments to the tail, thrust, CG and the use of Gurney flaps on the wing TE. Music: "Loveable" by www.bensound.com

I’ve drawn a detailed plan in the style of our late mentor, Dave Rees. The fullsized plan with documentation packet is available for digital download, print ready at 34.5” x 48”.

Mine was printed on blueprint paper via Staples, but any other group with
the printing resources should be able to accommodate.
