More Massive Droner HGLRC F440

I built this with a few goals in mind.

  • Better than my 3 inch babyhawk r
  • Use a stack for simplicity and have more room to grow
  • dshot1200 and 32 bit esc
  • F4 processsor
  • A strong sturdy frame (I crash bad sometimes)
  • Red colors

I used the HGLRC F440 40 amp esc stack for simplicity and growth. The motors will never reach get close to peak draw since this stack can be used 6s and with 5 inch motors. Also, got esc telemetry and smart audio working.

I ran into some issues with the F440 stack. The first one fried. Was replaced by racedayquads. I then broke the second one for being stupid and using dampening bolts between the esc and fc. This caused the pins to break. OOPS. We all learn something new everyday right? They just allowed to much flexing and broke the pins.

First, flight was great. Flew amazing. Tried a few different props out. Using a slightly modified version of the 4S Emax Babyhawk R recomended settings. They can be found here http://emax-usa.com/news/new-pids-for-the-babyhawk-race-3-inch-version/

Hovers at about 28% throttle and screams at 75%. Have not done anything full throttle yet. Will post a video of a recording if I make a decent run this weekend. With the 3076 propellors it sounds like the angriest hornets nest imaginable.

Weighs in at 278 grams at the moment. Conservative thrust per motor is 500 grams. So, pretty wicked thrust to weight ratio.

I have smart audio and esc telemetry working. I think that is all of them. But, no expert... Setup for those was easy.

Yep. It will happen on my next purchase. There is a pad for it.

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..
