About this Plan

Sig Komander Mark II. R/C intermediate trainer for .40 - .50 power. This kit included a foam wing and a pre-formed plastic cowl.

Quote: "The Komander is the grandaddy of SIG's current top of intermediate level RC trainers (the others being the Kavalier and the Mid-Star). All three airplanes are designed for those who want a second RC model that is more aerobatic than their priimary trainer, yet is still stable enough for them to handle. Most often mentioned by Komander enthusiasts are the plane's large size, honest and forgiving flying characteristics, and its rugged construction. The big semi-symmetrical foam-core wing has the precise amount of wingtip washout to provide superior stability and control on landing approach. As an intermediate trainer or a rugged sport flier, the Komander has a lot to offer!"

Hello, I was given your site as a location to submit plans for a Sig Komander. Please see attached. Dave Zotzman

Note: This kit plan is (to say the least) short of detail for scratchbuilders. It is an assembly drawing that came along with a box full of kit parts. Without the parts to hand, the drawing is ...sketchy. Does anyone have more details/drawings they can add, that would make scratchbuilding this model more viable? [Edit: we now have the kit intructions thanks to rcav8tr2, also faux plan thanks to JeffGreen]

Note: Model photo (boxart pic) was found online at the excellent Wells' R/C Airplanes blog site http://wellsradiocontrol.blogspot.co.uk/2014/06/sig-komander.html ...which includes lots more useful background on the Komander design.

Direct submission to Outerzone.

Update 29/08/2017: added Building & Flying Instructions, thanks to rcav8tr2.

Update 13/12/2017: replaced Building & Flying Instructions with the correct version, thanks to Jay. Previous version was actually for the Komander MkI.

Update 15/08/2018: Added 'Faux' plan drawing, thanks to JeffGreen:

Quote: "Hello, I created this PDF for the Sig Komander oz9124. Please note that the wood sizes and all the other details that I have omitted are all shown in the PDF's of the original kit plans & instructions, along with the photos that I used to base my dimensions on. So please plan accordingly, this is just what I came up with to help anyone who wants to scratch build the model. I should have something for a built up wing soon."

Update 14/09/2018: Replaced Faux plan file with revised version (v3), thanks to JeffGreen.

Update 25/09/2018: Added another revised version of the Faux plan (v4), now a much smaller filesize, thanks to rchopper56.

Quote: "Hi Steve and Mary, I have taken Jeff Green's excellent scans of the Komander and rearranged sheet 1 so that that both sheets can be printed on a 36 in wide printer. I removed the color photo and then used it as sheet 1 so that original sheet 1 can now be a bit TIF file. This 3 page file is about 15% of the faux_plan_v3.pdf I have increased the dpi from 72 of the originals to 250. We now have a full size fuselage and full size wing for the Komander thanks to Jeff Green. Gene"

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

Partial plan.

Indeed. Or not, depending how you look at it. This is the only plan drawing that came with the kit. In the middle of the plan it says: "This is the only plan needed to build the Komander". But yes, I take your point.

In fact Sig used to print directly on balsa sheets all the necessary outline for some of their kits. Just for comparison you can see the plan/manual pdf of a similar kit today, the Kougar, in the SIG site manual download section.

Steve and Mary, Thanks for your efforts with Outerzone, a fantastic website that I check frequently. Attached is the Komander instruction booklet you may elect to post [see supplementary file]. I still have a flyable Komander that is about 40 years old. The canopy attachment was tricky, I laid up a few layers of fiberglass on the wing upper surface, like making form fitting gear doors, to completely seal the canopy and stiffen it, This was then trimmed and glued to aft end of canopy to create a canopy module.

Just need wing definition now.

* 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.
