About this Plan

Weymann Lepere. Peanut scale parasol model.

Quote: "Dave Linstrum presents his Peanut version of a between-the-wars French observation a/c.

Doc Martin of my MIAMA club built one of these ages ago to fly in the Opa Locka Blimp Hangar and early US Indoor Champs at West Baden in the 100 foot Atrium of the Northwood Institute. With a strong Farman influence, including the distinctive fin, this silver and black all-metal military design has great proportions for a Peanut. We have simplified Doc's design to make it easier for novices, but if you build it light, it will be a great flier.You may want to use dihedral for stability.

Are you ready to build this military flyer? The skele-ton photo will show the major framework assembled and the plans are fully annotated, so we won't give you step-by-step assembly instructions here.

It is best to add some details like ID numbers, trim etc. before covering, but after any airbrushing of tissue. Cover using thin white glue - remember no dope any-where on model. A #8 and #5 Indian ink technical pen make a great pair for lettering and control outlines, etc. It is non-smear and permanent.

We have found that trimming high-wing monoplanes like this one is easier if you build in some down and right thrust, adjusting for a loose right hand circle in the climb. Outdoors the glide is a minor part of flight and indoor the prop should turn in cruise until touchdown. The CG balance point should be as shown on side view. Add strip solder under nose to adjust - we prefer this to plasticine, although that is traditional.

Be sure you have the correct wing washout at tips. A bit of washin (TE low) in the right wing, or a paper trim tab bent down, can keep the right wing up in a turn.

Attention, Mon Ami! Let's go look for the Boche, who may be building tip his airborne might again after the VersaillesTreaty. Let's be part of French history as we go on a Golden Age dawn patrol. Bonne Chance!"

Datafile:

ScaleType:
  • NotFound | help

    This is a scale plan, but ScaleType is set as NotFound.

    This happens when we can't find a relevant Wikipedia page to link to. Usually because the type in question is uncommon.

    Corrections? Use the correction form to tell us the new ScaleType link we should be using. Thanks.

Notes

* 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.

Scaling

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.
