Grumman Mohawk (oz1109)
About this Plan
Grumman Mohawk. Control line twin scale model, for K&B 15 power.
Quote: "Grumman Mohawk. Here is an unusual scale model with an unusual color scheme. Proportions for an authentic copy are excellent, with a long tail moment and general 'clean' overall shape. The variety of contrasting colors is enough to pop the eyes of any judge at a flying scale meet.
Care has been exercised to stay within the 'exact scale' area, with but two exceptions. One is the tail section, which is thinned for lightness and easy construction. The other deviation from scale is a simplified 'greenhouse' up front. True scale here would mean carving large canopy forms and heat-forming the puffed compound-curved sections for all areas but the windshield, which is flat. Since a great many potential builders falter and quit when it comes to any 'blown' style canopy, a somewhat simplified version is shown on the plans. Any celluloid of .020" to .035" thickness will do the job.
It is best to start with the wing of this particular design. Cut the required ribs, then the spar. It will be possible to cut a one-piece spar from a piece of 1/8 x 3" x 36" stock, but a spliced one will do as well, since the strength in this wing is in its covering and system of sub-spars. After cutting out a plywood spar brace, carefully attach it to the spar and allow to dry thoroughly. You can cut out formers or tail parts in the meanwhile.
Once the rib positions have been marked on the spar, the center section can be assembled over the plan. A very slight crack is all that is needed in the 1/8 x 3/16 sub-spars where the dihedral starts. Now before sheeting is applied, mount the bellcrank. For the lead-outs to come through the wing in the required manner, mount the bellcrank platform exactly as shown in the side view..."

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

ScaleType: This (oz1109) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Grumman_OV-1_Mohawk
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
