28% Cap 232 Assembly Manual Step 1. Open and inspect everything This section should be fairly self explanatory. In the large box you should have a fuselage with hatch., wing tube and stab tube, the eleva- tor/stab assemblies, the rudder, cowl, wheel pants, canopy, landing gear and packages with the tail wheel assembly miscellaneous nuts and bolts.

Clean out the hinge holes. Without removing any wood, use a very sharp X-acto knife and re- move any covering that may have been pushed into the hinge holes. It is very important that the glue sticks to the wood and not to the covering. See the section on hinging before you do this. Hardening holes.
28% Cap 232 Assembly Manual Step 2. Engine mounting The first thing to do, before anything else goes in the fuselage, is to get the engine mounted and aligned with the cowl. Here’s how I have done it. This is the hardest and most time consuming step in building this plane.

Mount the cowl using the supplied screws and washers. Place your spinner back plate over the crankshaft or prop bolt so that it is centered. You can now just move the engine around to get the spinner back plate centered on the cowl face. Once the spinner back plate and engine are in the right po- sition, remove the cowl and mark the location where the engine is standing before removing it.

28% Cap 232 Assembly Manual Step 3. Hinging the control surfaces Hinging is a very simple matter. We recommend that you hinge all the control surfaces in two steps allowing the glue to dry between steps. Before you start gluing anything, test fit each control surface. Aileron to wing, elevator to stabi- lizer, rudder to fin/fuse, with the hinges in place.

action does not push one of the hinges out of the hole. 8. After the glue is set flex the hinges back and forth to break away any glue that might have stuck to the knuckle. 9. Repeat steps 1 through 5 on the other surface 10.

28% Cap 232 Assembly Manual Step 4. Mounting the hatch and canopy The hatch mounts to the fuselage by two tabs on each side that are attached at the rear of the hatch. The holes for mounting the hatch are pre-drilled and 4-40 blind nuts are already in- stalled, you only need to find the hole under the covering and open it up with a knife or a hot nail.

28% Cap 232 Assembly Manual Step 5. Install horizontal stabilizer This step is easy. Trim the covering around the holes in the fuse for the stab spar tube and the two retaining screw holes on each side. You should also cut away the covering over the holes for the ele- vator servos, but don’t cut out the rudder servo covering yet.

28% Cap 232 Assembly Manual Step 6. Install control horns on all surfaces We recommend Dubro #866 or similar control horns with a 8-32 screw used for the horn. In our hardware kit we supply a version of this horn set with parts for one complete airplane.
Here’s a tip. When you cut the head off with your Dremel, it will be hot. Don’t let it fall on your legs or on the covering or it will burn through the covering (or your skin or pants). Rudder tiller; After the upper hardpoint has been drilled through with a 9/64 drill, install the tiller bar so that it is showing the same amount of threads on each side of the rudder.
28% Cap 232 Assembly Manual Step 7. Installing the servos 1. Elevator servos. Trim away the covering from the rear sides of the fuselage to expose the two servo trays. At- tach a servo extension to the servo cord long enough to reach the receiver, and tie this servo connector together with dental floss or whatever you prefer.
Page 18
If tail weight is not needed, I suggest that you mount a single powerful digital servo such as a JR 8611 or Hitec 5955 in the servo tray and use pull-pull cables to actuate the rudder. If neces- sary there is a second servo cutout which can be used to gang two servos for the rudder and still use pull-pull.
28% Cap 232 Assembly Manual Step 8. Install the landing gear There should be drilled holes in the landing gear plate under the covering, these should match up with the holes in the landing gear. Unfortunately the holes are not always there. To assure perfect alignment use the following procedure.

28% Cap 232 Assembly Manual Steps 9, 10, 11. Installation of fuel system, radio and con- trol linkages These 3 subjects are combined on one page because this is the part where you get to do things your way. We have only done a few things to get you started.
Page 21
Please use good strong pushrods and other linkage parts. A sample of the assembly that we used is shown in the picture below. Notice we use carbon fiber pushrods and Dubro HD horns. The servo connection is done with Sullivan 4-40 or Dubro clevises, or with HD 4-40 ball links. Avoid using ball-links with plastic servo arms, they generate a twisting force on the servo arms that will fatigue and fail.

28% Cap 232 Assembly Manual Step 12. Mounting the wings Push the 1.25 inch aluminum tube spar through the tube in the fuselage until it protrudes an equal distance on both sides. Carefully push each wing onto the tube until the anti-rotation dow- els engage the holes in the fuselage side.
28% Cap 232 Assembly Manual Steps 13 and 14. Balance the plane and adjust control throws The first flight should be done with the plane balanced as shown in table below. If you can get it to balance a little farther forward it will add stability.
