High Resolution Pictures of Launcher



So I thought I would get some close up shots and higher res video to show some of the finer details of the launcher. Like most things in this hobby it didn't go to plan as when i went to take off the Esc and Motor smoked themselves, so no launch, and after borrowing a friends motor found that he uses…

Diy drone launcher

 

Today I christened my new plane launcher with success. I have built this as I have found the properties where I want to fly from have little or no adequate takeoff areas since the fields are full of waist high grass or lots of rough ground. Landing is OK by slowing down and dropping into the long grass but takeoff has been hazardous, to say the…

Slow and steady progress, wings cut and mounted

This is taking longer than i thought but happy with progress in the last two weeks or so. I got the wing cores cut (by Glenn at OfftheEdge)and proceeded to wing bag the centre section. This was a disaster as i tried to get too fancy and mylar the top which resulted in a very heavy section, I have since decided to mount the wing either side of the fuse and reduce the wing span by 350mm.



So i have now mounted the wings either side of the fuse snd will proceed with the design from… Continue

UAV Fuse Vacuum Bagging - Unwrapping

ok, so home from dinner and ready to unwrap to see how it goes.

the good news is the cling wrap released from the wooden mold, and is actually very smooth on the inside, there are a few crinkles in the outer carbon, but these will not be noticeable once the excess is trimmed to size and glued to the 2nd half. 

the fuse is very rigid already…
