Nice freestyle build for a new pilot. The drone is build from decent components for reasonable price. The weight of the quad is 357 grams. The micro camera fits there using the 3D printed adapter.

I keep looking at your builds and biting my tongue, but I have to say something . This is one of MANY builds you have posted, that say they are for NEW pilots, but you don't provide strain relief on your main battery leads. I see that you even provided some abrasian relief, so you KNOW that the battery wires need attention. Why would you make a quad for a new pilot, who will likely have several battery ejection crashes in the next few months, knowing that they will have to replace a 4n1 esc just because you didn't bother to zip-tie your battery leads to some part of the frame? I went back and looked through your previous posts, thinking that you hade done this more than once in the past. Close to half of your builds don't have strain relief on the battery leads, and some of them are running RIGHT NEXT TO A ZIP TIE that you just havent used for the battery lead. WHY?!?!?

Hello Jodie, the reason we posted so many builds for new pilots is that we posted here also the drones we build for our customers (who are usually new pilots). About the battery leads. It surely needs some attention. We fixed them to the arm when we use the small stacks with small solder pads. When you use some bigger ESC like this one, there is a lot of copper and it can handle some stress. Also, the battery wires are secured between the top plate and antenna mount. The tape around the wires is there for two reasons. The first is to protect the wires from being cut by the edge of the top plate. The second one is to make the wires bigger so it slightly squeezed there and hold on place. Also, you know think about when and why are the ESCs damaged. It usually is when the solder pads are small (obviously) and when the wires are short. When you have long wires, they bend and the battery simply unplugs instead of damaging the ESCs. But you are right that you can't make a mistake by securing the wires to the frame by a zip tie or a tape. We just don't think that it is necessary in this case.

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
