Wow wow wow, has it really been three years since 2020? I had a blast building and flying so many planes throughout 2020, and then I got sidetracked by wrapping up senior year of high school and the start of my college career. Now, it's winter break of my sophomore year in college, and I finally have some time again to mess around with RC planes! I've had a GoPro lying around for a while with no plane to use it on, and I really enjoyed flying the smaller delta wing I made in 2020, so I decided that this time I'll make a bigger delta wing with a GoPro mount!
Step one was to shape the main portion of the delta wing: the wings! The wings will make up the bulk of the plane. Using plans for the FTVersa from Flitetest, I printed out the cutouts on dollar tree foamboard and cut out two wings. These wings needed a lot of creases in order to help the form bend to the shape of the airfoil. It also needed a thick double-layer spar the length of the wing in order to give it some more rigidity. I pre-cut all the necessary servo holes, and also trimmed the ailerons to make sure they'd have enough freedom of travel. After all the cuts were made, I just used some hot glue to fold the wing over to create the airfoil and secure the shape of the wing! You can see the two wings side by side, and it's staring to look like a proper delta wing! But we're still missing some pieces.
A very important aspect of this particular delta wing is that it has a roomy midsection to store it's electronics and camera gear. The midsection includes two foam doors on the top for easy access to stuff like the reciever, battery, etc. In addition, this midsection provides more surface area for lift. This allows it to carry more weight, and it also makes it better suited for easy cruising. After adding the midsection and gluing the wings onto the side, the last step was just to attach the side fins for stability!
Last step! It's time to install all the electronics. I decided to retire the B.A.T. that I made a while back, and I scavenged a bunch of electronics in the process. I reused all of the electronics except the motor since I needed a larger motor for the delta wing. After installing the servo and motor (using 3D printed mounts), I cut out a spot in the front of the plane for a GoPro to sit. I glued a shortened paint stick to the bottom of the spot for the GoPro mount in order to have a hard spot for the GoPro to strap onto, and then I strapped a GoPro on! At this point, the plane was looking done, and after taping up some crucial joints for added rigidity, I headed to my local field for a maiden flight!
Hand launch went okay! Was a little more bouncy at the start, but evened out as I got a feel for it.
The wind was strong today! Came to a near halt in the air as it turned into the wind.
A little rough getting it to line up because of the wind, but ultimately turned out to be a smooth landing!
All in all, this was a great first experience using a GoPro on a plane. The shots came out looking super cool, so I defintely want to do it again sometime. Next time, I'll just hope for a little less wind! I may also want to add just a little more nose weight to help the delta wing track better in the air and eliminate wobble.
