Intro: Ice Cream Glider
Was just trying to enter into micro/mini rc. So i decided to make a prototype model from stuff lying around. Will add radio control later. Right now its a simple glider what i intend to make.
Here is what you will require :
Ice-cream Sticks ... 0.06$ for 12
Cyano-acrylate glue ... 0.1$
A marker pen
Depron/ Biofoam plates
Step 1: Making Airfoil Ribs
Make airfoil shapes on the depron plates. I made a general shape as it is just a prototype. You can choose clarky-y profile. For beginners it is not much important to get the shape correct. Just make sure al the ribs when cut should be sanded to match each other perfectly.
Cut all the shapes carefully with a cutter..i made 8 four on each wing. After cutting all the airfoils..you can sand them to match each other...but i was lazy enough to do that. Once you are done with the airfoils,leave them aside for the time being..we will now create the fuse and wing structure with ice cream sticks.
Step 2: Making Wing Structure
Please be very carefull while cutting ice cream sticks...the proper way to cut them is similar to how we cut a glass. Just use many cutting strokes with small feed depths and then pop them into two.
Cut two ice cream sticks length wise at the middle. I used the max length i could get from one stick. So i now have 4 long half sticks. Take another full stick and cut it into two at the middle but not along the length...alongh the breadth...and then cut these 2 half sticks along the length....so now you have 4 small half sticks.
See the pics for reference.
Step 3: Adding Dihedral
Cut a slight bevel on the small half stick and join it with the full length one. see pics for clarifications. I used a standard 0.2$ cutter do do all the bevelling ans no sanding was done ever.
Repeat for all 4 sticks.
Step 4: Completing the Wing Structure
Now determine the chord of your wing and cut six pieces of the same length from the ice cream sticks. Join them to the main wing sticks as shown in figure. You need minimum 4 sticks or the structure will not be stable. The pic doesnt show the third and fourth stick but you can join it near the start of the dihedral and somewhere in the middle of the wing.
Step 5: Adding Airfoil Ribs to Wing
Now after your wing frame is ready...glue the airfoils..i used Cyano-acrylate glue for that. Refer the pic. Repeat these steps for the other wing. Make sure to make the join between the two wing halfs strong.
Step 6: Rudder and Stabilizer
Complete the horizontal and vertical stab on similar lines...refer the pic.
Step 7: Covering the Wing and Empennage
Use a standard tracing paper to cover the wings, rudder and the stabilizer. After covering each component glue the rudder to the stabilizer as shown in pic.
Step 8: Adding Dowels to Wing for Mounting
Just glue two stick at the underside of the wing. This will be used for mounting on the fuselage. Refer the pics for clarification.
Step 9: Fuselage
Take two ice cream sticks and glue them together to make a stick type fuselage. The glue the wing and the stabilizer/rudder assembly to the stick fuselage.
Add clay nose-weight to the fuse to adjust CG at around 30% of the chord to get optimal flight characteristics. You Ice cream glider is now ready to fly.
