Steve, I am either a modern wus who can't figure out plans, or this plan doesn't have enough to build from. None of the formers are shown. I am wondering if anyone on RCGroups ever built this, or someone from SAM. This would be a cool plane to build. I want one big old timer, surely wouldn't be ready for this season, but maybe next. This gull wing is neat. Cheers,

Good point - no formers. Have reset this to incomplete now. It's a fine drawing, let's hope someone can add more detail on this one. I'd love to se a photo of a completed model. Gotta love anything with a gull wing.

A photo of Tom Mountjoy holding his Gull Wing Sportster, taken in 1940, can be viewed in the March/April 1989 issue of Model Builder magazine. The photo is presented in John Pond’s column “Plug Sparks” on page 33. Pond addresses the photo on page 100:
Recently this writer received a flock of photos he had submitted for use in his column over the years. Also in the large box were a considerable number of letters with photos from modelers who were quite enthusiastic about the Old Timer column.
In picking through them, a letter from Tom Mountjoy caught my eye with a Photo (No. 5) taken at East Patterson, New Jersey, in 1940. Seen in the photo is Tom Mountjoy holding his Gull Wing Sportster which later appeared in the July 1941 issue of Flying Aces. Tom's model was powered by a Forster 99 with a hand-carved propeller. Flew it 21 times in a row without a scratch (what luck!).
Tom would like to know who are those fellows directly behind the tail? Tom also adds he won the Beauty event that day. Fortunately, only one official flight was required. (Col. note: this guy is just plain lucky!)

Yup, "1941" is error. It's 1942.

Thanks Aaron, have included a copy of that photo as the main model pic now.

While my eye caught the error of a wrong year stated in the Model Builder article ("1941"), I overlooked another error of a wrong month stated ("July"). I want to clarify here that the correct issue date is August 1942.

* 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.
