Henry Struck's 1937 Benny Boxcar
Scaled to 108 inch span
The Benny Boxcar was an early Struck design and was not presented in plan form until much later. It is a great flyer and builds light. The photo was taken at Boulder, Nevada at the
2019 SAM Champs by Mike Clancy. The motor I installed is a Neu 1509 1.5-6.7 with a Hobby King motor mount.The Boxcar handles high power very well and has a very long flat glide.

plans are detailed with building notes and show every part. Plans
are $33 plus postage. Laser cut partial kits
are available for $154 plus postage as of 4/21/2020. Please contact me before ordering as balsa wood prices are very high and volatile at present.
Strip wood and sheet balsa will need to be added. Postage is only charged once for orders for both plans and parts.
USPS has made another major increase in postage costs. To allow me
to quote the cost of postage please contact
me at firstname.lastname@example.org with your address and I will calculate the actual postage.
