About this Plan

Lanzo Bomber. Free flight gas model, for Ohlsson .60 engine. Wingspan 96 in, wing area 1260 sq in.

Note this is the nearest thing we have to an original Bomber plan (quote "traced from original drawings"), so we have set this listing as the primary, and will link to here from all other Lanzo Bomber listings.

Quote: "The Bomber is a 1938 free flight design by Chester D Lanzo. Traced by Ralph E Turner from original drawings, 1980. Specifications: wingspan 96in. Wing area 1260 sq in."

Direct submission to Outerzone.

Update 22/4/2022: Added airfoil data drawing, thanks to TomRyan.

Quote: "Confusion persists about Lanzo Aerofoils. E.g: The Puss Moth has been published with a flat bottomed and an undercambered aerofoil. When the Bomber was approved by SAM in the early eighties, it was assumed to have the same aerofoil as the Record Breaker because the Long-Center Section version has the same wing planform. This was not the case. The R/C Stick did not specify an aerofoil and variations abound.
I found this blueprint in a box of tissue scraps left by the late Bucky Walter who worked with Chester Lanzo at NASA. I never met Mr. Hoffman but I'm guessing he was also a colleague or, at least, a fellow member of SAM Chapter 39. "

Supplementary file notes

Airfoil data.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Check wing center and tips joint before you build, on the original plans, these did not match!

I have a few photos of the Lanzo Bomber [more pics 003-005]. It used to be free flight, once landed in the water even. It took about an hour for it to float to shore, almost no wind. Later due to loss of flying site I converted it to r.c. with the same engine it used for free light. Not flown it after conversion yet.

Hi Steve, hi Mary. Here are some photos of my LANZO BOMBER [morepics 006-008]. Now it flies beautifully with a Super Cyclone spark.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
