FPV Ground Station Part 3

I designed a case for the electronics circuit board tonight. It will be laser cut out of 1/8" plywood and then glued together. The ports are for (left to right): 3s battery, TX signal to Dragonlink by servo cable, video RX to the 5.8 GHz repeater by servo cable, window for digital voltage indicator, and antenna for the 5.8 GHz repeater. The case will then be secured by screws into the back of the biquad antenna so everything but the Dragonlink module can be removed from the tripod in one piece. I will update this post with pictures of the final product but it may be awhile because I still need to order the digital voltage indicator.

Mini Hotliner

Here is a project I did a while back. My uncle was cleaning up his workbench and as a fellow RC modeler he gave me some random wings and fuselages. One of the wings was about the size of the wing on the Slipso400, a small hotliner I found on this RCGroups thread: Slipso400 . With a few modifications I managed to get it to be about the same wing. For the ailerons, I decided to try a linkage which keeps the servo in the middle of the wing and joins both aileron surfaces to the motion of one servo. The fuselage was built off of the plans provided in the RCG thread. The bulkheads are lasercut from 3mm plywood. The side walls, top, and bottom are 6mm depron. I wanted to make the tail a little stiffer so I shaped some thin pieces of balsa to the profile of the tail. I left a small space in between the two pieces to run a plastic tube to route the push rod for the elevator. After putting in the servo and gluing it all together, I rounded the edges wit...

FPV Ground Station Part 1

Since I live in Illinois it is hard to get out to fly in the winter due to the dreadful weather. So I decided to use my time indoors building a ground station so that when the weather becomes more bearable I will be ready for some fun flights. Setup will look something like this I have about a five foot tall tripod that I will use as the base for all of my equipment. To start I drew out a general schematic of how I wanted to set it up. Dragonlink V2 for control on the top of the extendable head, 1.3 GHz biquad antenna for video on the top of the legs, and an electronics box somewhere in the middle. This will have a 2.4 GHz FrSky D4RII receiver to use as the link from my transmitter to the Dragonlink. Also, I will run the video out from the receiver through a DVR and then into the 5.8 GHz transmitter to repeat the signal to either my goggles or monitor. To reduce the wiring I decided to build an electronics box. This will hold all of the components mentioned and using ...

Depron Mini Skywalker

The 1680mm size Skywalker is a great plane and I have read lots of good things about its little brother. So I decided to try my hand at building a Mini Skywalker. Scaled to about 95% First, I found some good pictures for getting the dimensions and general design. Then, I used the pictures with a few known dimensions to find the rest of them and I drew out the most important parts. I used 6mm Depron with for most of it and some 1" EPS to thicken the nose for space to put my battery and other components. For the wing, I did a fold over style Armin-type airfoil with packing tape on one side. This was my first wing built this way so it didn't turn out great but I think it will do the job. I put a small carbon spar at about 1/3 of the chord. HXT500 5 gram servo installation Fuselage wall Both walls with 1" EPS block to thicken the front Approximate layout I am using an old mini quad motor, 2204 2300kv, with a 5045 prop, FrSky D4RII...
