A second big baby x8... Crazy I know
By SlightlyScratchedCorolla on Oct 20, 2020
This time I used 25mm standoffs (vs 30mm), 20x20 boards, and 14 vs 12 awg battery lead, hoping to make a lighter rig with lower cg. Wanted to use 1408 for little more top end, but did not find ideal ones, then I saw these black unibell micro Xings 1507 when I was browsing canola oil on Amazon, couldn't resist its boba-like cuteness.
The end result is only 5g lighter dry weight. I practically failed my goal. I didn't weigh these motors but they have to be the reason. I think it is worth trying get rid of the tpu landing gear, push the gopro to the middle and bottom mount the battery.
Maiden with a light 850mah pack, all jitters are my shaky fingers

"browsing for canola oil" - Not buying it.
Don't make excuses...I'm sure the wallet is crying out in pain...
Have you tried powering the GoPro off the LiPo yet? Saves a good bit of weight from what I've heard (I don't have one myself)
In all fairness I did buy oil, just cheaper vegetable oil instead of canola, for the obvious reason.
Nope I have not tried powering the GoPro off the lipo, but I've heard good things about it. Thanks for the tip! I'm happy with how it flies on 6s 850mah but the fly time is around 2.5 minutes, I may do that in the future to use bigger batteries.
Goodness! And I thought that I had poor impulse control... ;-)
Strong work all round!!

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

I have all the parts and looking to start this build. I have a few questions if you don't mind, are you able to access all the motors and esc's on Bl-heli 32? Never done 8 before, have done 6 but they were old esc's, I think Simon K and just re-soldered the wires to change direction. Also any tips on betaflight or the build it's self would be appreciated. :-)
Yessir BL32 works on all the motors and esc in this setup. And the build process overall is easier than it looks, use two 4-in-1 escs for simplicity, just a lot of soldering. As for BF settings, change quad x to octo x8 in the mixer scroll down menu and set up your motor rotations the rest is basically the same as configuring a quad.
