Another tool used in balsa model building that can come in handy for foam board models. The Easy Cutter is great for making clean cuts in skewers and popsicle sticks. And if you need cuts at angles, the Easy Cutter has a protractor that gives you pretty close approximations of several angles. I checked a couple of online suppliers and this product is still available.
After building balsa model airplanes for many years I have accumulated a variety of building tools. Not all work with foam board, but many do. The Master Airscrew Balsa Stripper is one of them. It easily cuts perfectly straight lines in standard foam board. The specs say that the maximum width of strips is 1/2″. Uses a #11 X-ACTO blades.
Building a wing for the FT Simple Storch. At one point you need to add a trailing edge spacer made from foam board. Wanted to get the long thin strip glued flush to the edge, so I made a gluing fence. The idea is to pin down the fence, then the wing touching it. I use balsa modeling pins. When you put the glue on the spacer strip you just need to push it up against the fence, then press down until the hot glue sets. These fences some in handy for lining things up during construction.
Using the Aldi Workzone glue gun the other day. I left it plugged in while I cut some foam board. Maybe about 30 minutes. Then when I went to use it I found that the glue stick had melted in the open feed area and it jammed the trigger; wouldn’t feed. Ended up taking an X-acto knife to cut the clog away. So if I plan on not using that gun for awhile, unplug to avoid this.
I brought the Flite Test Old Speedster to the September Meeting for the Show & Tell. Here is the video.
Finished the Old Speedster and decided to taxi it around the back yard to make sure everything is working correctly. Looks like it is. Next is to take it to the field on a not windy morning. The landing gear is from a MultiPlex FunCub.
The landing gear on the Old Speedster is held on with one rubber band. When I assembled my Speedster and installed a battery the landing gear was sagging. Check the first picture. I tried adding a second rubber band but the skewers were beginning to bend and the model was still sagging, so I decided to see if I could come up with something that would work better for me. It involved a foam board landing gear doubler with some bamboo skewers. The doubler gets hot glued inside the fuselage above the original landing gear mount point. The 1/2″ round holes were made with a FoamWerks Drill. It worked great.
Several years ago I bought my first Multiplex FunCub. One distinguishing feature is the tundra tires. Not just for looks, they help get through thick grass. And so since then I have been putting large wheels on all of my R/C model airplanes. The tires shown in the pictures below are the ones that come with the FunCub. Yes, you can still buy them.
Not all mini glue guns and mini glue sticks are equal. When I was using my Aldi Workzone gun I needed to put in a new glue stick. I squeezed the trigger half way before any glue came out. Wasn’t sure what the problem was. What I discovered after taking some measurements and doing some research is that the Aldi gun takes 5/16″ (.31″) glue sticks and what I put in was a 9/32″ (.28″) glue stick. it doesn’t sound like much of a difference. But if you try to put the larger glue stick into a smaller glue gun, it won’t fit. And if you put the smaller stick into a larger gun not much glue will come out when you squeeze the trigger. My assumption was that all mini glue guns and glue sticks were the same. Not so. The point is that if you use a mini glue gun, just know what size it is so you buy the right size glue sticks.
Years ago we used wheel collars to keep the wheels on the axles. Here is another option. Use #4 flat washers and small silicone fuel tubing. Use this sequence. Put the wheel on the axle, then the washer, then squeeze on the fuel tubing before you cut it. If you cut a small piece and then try to squeeze it on, it will be difficult. Cut the tubing after it is in place on the axle.
