About this Plan

Beechcraft Baron 58P. Radio control scale twin. Wingspan 70-1/2 in.

Update 10/04/2018: Added pdf sheet with (unofficial) fuselage formers drawn, thanks to JeffGreen.

Quote: "I needed the patterns for the some of the parts not shown on the plans for a'"foamy' Baron 58 that I'm building & created this PDF. I only had some old photos in my r/c files to work with, so please note that these are not exact copies of the kit parts."

Update 30/6/2022: Added kit manual, thanks to JeffGreen.

Quote: "First, select the scale ratio you will use. This has been approximated in our kits because there are so many variants between each different series of the basic air plane. You may choose the series which is closest to our kit - still you will have to make adjustments, perhaps an inch in wingspan, 1/2 inch in length or so on. The point is - this is the time to plan for these adjustments and they must all be the same ratio for maximum points.

The easiest way to do this is to obtain a pair of proportional dividers. This is a tool with a moveable pivot in the middle and when open looks like an 'X' with needle points at each tip. With these you may set the ratio so that measuring with one end off the 3-view will give the desired measurement at the other end. Carefully adjust time drawings we've provided to exactly match the 3-view you will use.

Next, carefully study the material you've gathered and make note of exactly which details you will include on your model and where and how they will be incorporated. For instance, do you plan on flaps? Retractable gear? Lights? Thousands of techniques are included in magazines and columns which are devoted to scale construction techniques so I'll leave you to hunt up all that for yourself.

We will now consider the basic airplane and then its construction.

Wing construction:
1. Note that the wing center sectionn is flat. All dihedral is outboard of the center section. Draw centerlines on all ribs from LE to TE. Cut all spars to length.
2. Laminate W-18 to W-3, W-19 to W-4 if you are using retracts. If a fixed gear installation is desired, laminate W-18A to W-1, W-18 to W-3 and W-19A to W-4.
3. Pin lower outboard main spar in place over plans. Add ribs W-1 , W-3 and W-5 to W-12. Do not glue. Fit upper spar in place,
4. Fit W-17A and W-17B plywood spar doublers in place.
5. Draw a center line on the leading edge, W-16 span,.Wise. Also W-15 and W-14.
6. Line up LE centerline with rib center lines and pin in place. Remember no glue yet.
7. Fit upper rear spar in place. Add W-4Aa, W-4B and W-4.
8. When satisfied that everything is straight, use a square for the ribs, glue parts in place. When dry, remove from plans.

9. Drill hole in W-22 and attach bellcrank. Glue assembly in place. Drill holes in ribs for aileron pushrod, do not install pushrod yet.
10. Glue W-20 's in place for retracts W-21 and W-21 a for fixed gear. If retracts make wheel wells from scrap balsa and put aside for now.
11. Glue lower rear spar in place.
12. Build other wing half in the same manner, by oiling plans so that you can see through them.
13. Now we have a wing with outer panels but no center section. The dihedral is built in at this point.
14. Pin the center lower spar in place on the plans. It should fit exact between the outer lower spars. Add the center section W-11's and the top center section spar. No glue.
15. Fit wing assembly in place over the center section. Measure tips for proper dihedral. Add W-14 and 5rs. Keep the center lines aligned,
16. Fit W-30's and W-31 is in place
17. When everything looks right, glue the parts in place, keep things straight... "

    ScaleType: This (oz6940) 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
    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.

The Royal photo was edited from a old kit box label and the Marutaka photo was pulled off the Internet [more pics 003, 004]. I'm pretty sure it was the label on the kit box. They make pretty good Desktop backgrounds.

These two pages are very well made! It's simple to understand and I will be very interested in building one of these along with the other few plans I have downloaded. I appreciate you sharing these plans!

* 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.
