Hello.
I have a wonderful amount of fun flying indoor fpv with my qr ladybird in the sports hall where my club is at. Actually i fly my ladybird more around the cafetaria instead of in the hall itself :banana
I do have trouble with interference. My fpv-system is 5.8 ghz and most halls i fly in are steel constructions. I end up with lots of flicker, sudden black-white image, sometimes colors which i cannot identify.. multipath.
I hoped to solve this problem by replacing my stock rubberduck antenna on my receiver with a circular polarized one. It helps a little, but it is still not ok to me.
So theres no other solution left but to install a circular polarized antenna on my vtx aswell, which will add even more weight to the little thing, and on the frame, theres alllready so little space. I also use pretty heavy 550 mah flight batteries, because i seem to get the longest flight time with them. (5 minutes)
So.. i decided to try something radical. I dismanteled the ladybird and made a new frame which is 2.5 grams lighter then the stock one (5 gram) while the center point is significantly bigger to get me more space to install my fpv-electronics.
The material that i used for this building project is not very common in our hobby, but it sure does what it needs to do
picture time =>
Indeed, the same stuff you find in packages of computer parts/tablets...
4 little pieces of balsa
basic frame is ready...
Now to fix the motors. Used strong glue to attach it to the frame and the end point of each piece of balsa
4 extra pieces of whateveritscalled to give a bit of support to the pieces of balsa.
I forgot to take more pictures, so all i can give now are pictures of the end result
First flight tests were positive. Next step is adding a circular antenna to the vtx
This is my very first building project and i am pretty proud of it ^^
