About this Plan

DH Mosquito. Scale model twin-engined WWII attack bomber, for rubber power. Wingspan 40-5/8 in. An Otto-O-Former kit.

Direct submission to Outerzone.

Quote: "Dear Steve, Here's a challenge! The patented building system is quite good. Cardboard formers don't splinter and break - Denis Rattle used them to good effect on his 163. I couldn't find decent Bristol board but spraymounted copy paper onto 1/32 sheet, works great. I used well-sanded 1/32 to form the fuselage tube around a 22 mm copper pipe. So the fuselage is quite simple to build but the wing is more difficult - one really needs extra tabs on the bottom of the ribs to enable it to be built flat on a board. It would also be sensible to omit the flaps and ailerons, better aerodynamically and lighter. The same comments apply to the tail surfaces, the separate controls need to go as does the intricate diagonal bracing.

The outline is surprisingly accurate, although, for example, the shape of the fin could be easily improved I suppose some people would prefer to keep it vintage and period. The nose is not bad but the glazing needs to be smaller.

Unfortunately the props and rubber drive system seem to come pretty low on Joe's priorities, after all reference is made on the plans to building the model for static display. The tubes shown are unlikely to house enough rubber for anything other than a ground-hugging glide. Prop details are notably sparse. They are contra rotating and seem to be formed from some sort of malleable fibre supplied in the kit but to have any chance of respectable performance one is going to have to get carving.

Because of Joe Ott’s construction method the drawings are largely superfluous. All you need are the former stations marked on the fuselage tube and the fuselage can then be constructed free hand. The wings are unequal, the fuselage longer on the plan than elevation. I would eliminate the extended motor tubes and redraw the nacelle formers with the same dia holes as the fuselage. The existing plans could be included as period fun but life is short!

Or you could just forget all about it and build Howard Boys' much more sensible Mk XVI which you will find elsewhere in Outerzone. But wouldn't it be great if someone set to and built one of these? I'm trying. Yours, Richard"

NOTES on this plan: This plan is listed here in an unusual manner, so do please pay attention, chaps:

1. The plan is listed as 'needs cleanup', but that's not a request for help, just a statement of print quality. Unless you are very excited about working on and cleaning up this plan, just disregard this.

2. The files are quite large, because the scan is 300 dpi and shows a lot of background noise. Sheet #1 has been run through the Photoshop DustAndScratches filter to lower the filesize - we do have a full 23Mb raw scan here for reference. Sheet #2 is the actual raw scan, unfiltered.

3. As Richard points out, the original paper plan itself is of dubious merit to the builder, with many inaccuracies. Therefore, we suggest anyone working on cleanup of this plan seriously consider splitting it into 2 distinct packages: one for builders simply needing templates with accuracy (on a white background), and another for art lovers wanting a poster to mount on the wall. Steve.

    ScaleType: This (oz13618) 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/De_Havilland_Mosquito
    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.
