About this Plan
Ker-mando. Control line combat model.
Quote: "Build a combat model for the gala days! Ker-Mando, by K Jacques.
Ker-Mando is one of the 'Ker' series of combat models flown by the Meanwood club at many galas and demonstrations (read 'Circus Capers' on page 222). Others are 'Ker-Unch','Ker-Tastrophe and even 'Ker-Laustrophobia'!
THE first item is the wing. Cut out enough rectangles of the appropriate thickness balsa for the wing ribs (just for now - forget that the central ones are smaller). Then stack them like playing cards and push two pins through from either side and, using the block method cut them to the outline of the tip rib, complete with notches for spars, LE and 'V' TE. Sand them. Break the pack in two and drill the lead-out holes in one set (watch that you don't split the wood). Enlarge the root holes a little.
Now, take one rib with the two lead-out holes and two ribs without any, and on the edges where the sheeting touches cut down the rib size by the necessary amount of 1/16 in. Lay one of the spars on the plan, and cement the ribs on to it, in their correct positions. Then add the LE, and top spar.
Pin one of the two TE strips to the plan and cement the wing ribs to it. When it is set, unpin it, and cement the other strip of the V TE to it. Pin it down to dry. Cut out the ply bellcrank, pre-cement all over, and make the bellcrank assembly complete with wires.
Now this bit is tricky - unless you cheat and temporarily remove a portion of the spar. Slide the lead-out wires down their appropriate holes (working from the centre) and wedge the assembly up against the rib and the two spars - apply cement and before it sets hard check that the wires are free. Now put in the sheeting - don't glue up the push-rod. You should have one large empty Britfix tube by now so put in your outer wing tip weight. Sandpaper this part smooth, then put it aside until the fuselage is ready for it.
Cut the engine bearers ('A') to shape, smear cement over them, and fix in a 'B.B.' or, better still, an old crankcase. Pop in the 1/4 x 3/8 piece 'B.' On top put on the 3/16 sheeting 'C' (grain crossways) sand this flush with the engine bearers. Put in the tank (Mercury Pressure) and the (or probably a little thinner) pieces 'G', again grain crossways..."

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

* 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.
