Building the Model Airways 1/16th Scale Sopwith Camel
Partial Kit 5 of 8
The Empennage
Well, I've made it to kit 5 of the 8 and it would seem to represent the start of the downhill part of the race. Not only are we now past halfway, but it looks like the hardest parts of the kit (other than that propeller) are already done.
After slogging through the bottom wing last month, the tail section was a breeze.
As with the wings, the tail starts with capping the ribs for the stabilizer.
Fortunately for my sanity, there are only eight and they're much smaller than the wing ribs.
While the glue on the ribs was drying, I assembled the fin and rudder.
The assembly is all metal. The fin and rudder are joined by crimping whitemetal hinges around them at the hinge points. Then the control horn is glued to the rudder.
There is only a single spar on the stabilizer and only eight ribs, so assembly is quick.
There is also no leading edge to carve. The whole rib and spar assembly is mounted inside the stabilizer frame. The center part of the spar need to be trimmed down to fit properly inside the frame.
Unlike the wings, the compression bars used for the cross rigging are wood pieces instead of metal, but otherwise the rigging process is similar. The wood then gets its Englisk Oak stain and varnish.
The elevator is attached with clamps the same as the rudder and the control horns are glued in place.
The rudder assembly is then attached to the stabilizer and the whole thing is then glued in place on the fuselage.
Since there are no locating pins or any of the other aids in a plastic kit, the aligment must be carefully checked. The fin must be vertical and centered and parallel to the fuselage center line. The stabilizer must be level and perpendicular to the center line.
The bracing rigging is then added. The control wires for the rudder and elevator are added next.
One long piece is used for the rudder. The "wire" is threaded through the hole at the back of the rudder with half on each side. Then on each side, it goes through the control horn, into the fuselage and under the seat to the rudder bar, then back under the seat and finally connects to the tailskid. Make sure that the rudderbar is centered along with the rudder and tailskid when tying off the lines.
I departed from the instructions while doing the elevator rigging. The instuctions say to start and end the run on the control stick, but it's way too tight in there to make that practical. I started by attaching the center of the cable to the stick and then running the free ends from there.
On each side, one cable runs from the front of the stick around a guide on the rudderbar, back under the seat, through the fuselage over the top of the stabilizer to the horn and is terminated at the back of the elevator. The other half runs from the back of the stick, under the seat to the bottom control horn and the back of the elevator. Again care must be taken to have the elevator and stick centered while all the wires are tightened and glued in place.
Rigging the controls can be frustrating as there is little room to work in the cockpit area and it all has to be done with tweasers. It's very easy to get a cable wrapped around another one or around some other piece of the fuselage while at the same time trying to keep everything taut and centered. I thought I had it done a couple of times only to realize a cable was tangled somewhere and had to be rerouted.
The end result however, is worth the struggle as moving the cockpit controls will move the control surfaces appropriately (or vice-versa).
The only things left are to build the landing gear, mount the wings, and build the engine - and the prop.
