Here is something interesting. Spektrum is now offering a receiver that does not need an external antenna! Remarkable. Just ordered one for the FT Simple Scout.
In this post I used a small, hobby table saw to cut the 45° bevel in the horizontal stabilizer. I left the stab in the surrounding foam board to maintain a line parallel to the saw blade, but removed the bottom few inches to adjust the saw cut.
The table saw is small so I needed to extend the fence to accommodate the the foam board that extended far beyond the table. To do that I taped a couple of yardsticks together then hot glued them to the table saw fence.
After the bevel has been cut I find it easiest to apply the tape hinge while the entire horizontal stabilizer / elevator assembly is pinned down.
To get the tape hinge centered I put a couple of pins toward the end of the stab as guides. The tape is 3/4″ wide so I put the pins in 3/8″ from the hinge line. Works great.
i had a question about tracing lines from the stab slots onto the balsa below. Here is a step by step. I used a small hobby table saw to cut the balsa. And then a small 5″ disc sander to clean up the edges. An X-ACTO saw and some sandpaper will do just as well.
If you are building the FT Simple Scout with the balsa stick rear fuselage, you may find that after gluing in the cross members the stabilizer tabs on the fuselage are slightly off from the stabilizer slots. One way to correct this is to make a spacer from balsa for a better fit. Could be a good idea to have the spacer in place before you glue in the last cross member. It might work with foam board. instead of balsa.
Just a couple of details about building with balsa sticks. Longerons are the long, weight bearing elements. The cross member supports add to the strength of the structure and also make assembly easier. The 3/16″ balsa tab fits into the horizontal stabilizer. If you view the plans for the Flitetest Simple Scout you can see where the balsa tab replaces the tab from the foam board fuselage side.
The bottom of the fuselage on the Simple Scout runs at an angle to the tail. So when cutting the balsa sticks the bottom needs to be cut at the same angle. The top of the stick is square, so no need to cut an angle. I made this cutting guide from a couple pieces of scrap foam board and one piece of 3/16″x3/16″ balsa stick. Just make your mark, then cut or sand the stick and glue it in place. Works really well to give you nice tight joints.
First I printed out a set of plans for the Flite Test Simple Scout. After that I drew some guide lines on the plans for the balsa sticks that I am going to add to the rear of the fuselage. Then I took the Flite Test Simple Scout fuselage and cut the rear off. Next step was to pin down the front of the fuselage to the plans and add the sticks to the rear. The idea here is to give the Scout a more vintage look.
This one is from the guys at Flite Test.
In an upcoming project I am going to start with a foam board model from Flite Test, then cut part of the fuselage off and replace the missing part with balsa sticks. Gluing balsa is different from gluing foam board, so I decided to review some basic balsa building techniques for the benefit of those who are unfamiliar with the process. Here is the setup that I use when building balsa models. In this picture the bottom is a balsa building board. Balsa building boards are difficult to find these days. Someone told me that an acoustic ceiling tile will work. There are occasionally single tiles available from a damaged package at your local home improvement store. Next layer is the plan sheet. On top is a piece of wax paper to prevent the wood glue from sticking to the plans. I usually use thumb tacks to hold the plans down and building pins, or straight pins, to hold the balsa in place while the glue dries. T-pins are still available from several suppliers, including Tower Hobbies.
My next project involves gluing balsa sticks to foam board. Since I want to make sure that I get a good glue joint I decided to do a test with the glues that I have available. Four glues to glue balsa sticks to pieces of foam board. Care to guess the winner? ALL of them! I was amazed. They all seemed to work very well. I went with Elmer’s. Been using it since 2nd grade and it never let me down.
