FPV replacement frame, compatible Petrel 75 Whoops

thingiverse

After beginning with my brain new FPV HGLRC Petrel 75, it' a great feeling to fly it, and what a frustration when I brake the frame. I ordered some replacement parts but how can I wait 4 weeks until it reach my mailbox? Impossible! No way! Then I designed quickly this replacement frame, with the idea to make a dirty repair and quick flight again. The design is made for simple printing, without support, using the printer bed flatness for precision and hardness improvement. I made few trys and finally the designed frame is good enough to put all together and power it again. And what a surprise, it was flighting very well!!! And even more, the battery seems lasting longer. Yesssss! It's flying again. The frame is more fragile than the original and slightly more heavy (original is 7 gramms, this one is 9 gramms). Anyway small damages can be repaired using a lighter to melt the PLA and form it again. Assembly of the controller and canopy with camera relys on 2 screws M1.6x16mm and 2 nuts, the 4 original silicone dampers are used to stabilize the stack of components. The battery is hold using a rubber band. Printing wiith thin layers of 0.2mm is ok. My nozzle is diameter 0.5mm but I cheat Cura by setting dia. 0.3mm, therefore the slicer is able to put 2 walls in the thin geometry of the bumpers around propellers.
