7inch Lion build

Update: I've mounted the front motors upside-down to get the props out of the gopro FOV
Update: I've replaced the diversity receiver with a micro v2 and made a TPU tail to hold the antennas in a better position

last test: 20min with Hero7 onboard on 6s1p 4000mAh (Samsung 40T 21600)
first test: 27min on a 6s1p Lion pack (Sony VTC6) -

car chasing with LiIon (read video description):

reelsteadygo test done on this frame:

big motor issue: contact surface with the propeler is flat and has no friction which combined with the fact that the nuts are low profile is the perfect formula for props coming off (untightening) mid flight. this is unacceptable for such a large motor which can spin 7inch props. V2 solved the issue.

frame issues you should know about:

  • 15mm standoffs are joke, had to replace them with 25mm ones.
  • captive nuts are not preinstalled as they should

hi,

thanks a lot

sry can't, someone else built it for me

Hey. I would like to know how you tuned that thing. Would you mind sharing your pid´s?

I am using an old betaflight FW, I doubt my PIDs would be of any help. what I can tell you is that PIDs have very little significance in long range builds and unless it flights bad you shouldn't bother with them. the most important aspect in my case was to configure the ESCs because in my case they were desyncing and cause some weired yaw twitches.

Great job on this build.
Could you share the STL of your tail for the 2 antennas (RX + VTX) ?

sry, I don't have it. a shop did it for me.

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
