Toothless is my first 7" build. Wanted to accomplish a Mid-Long Range Build with GPS, Rescue Mode, LEDs and a long flight time.
Was going to be my first crossfire quad but went with trying the Frsky Rx6R instead.

LED Switch -

Second Flight -

First Flight Log:

  1. The motors would only start to spin until given about 10% or more on the throttle stick.
  2. Drone would spaz out when going trying to do flips or rolls.
  3. The RX would cut out at about 20-30 feet away in an open field.
  4. No hot motors.
  5. Really good video feed.

Swapped the antennas out on the original RX4R, did little to nothing. Then did a swap on the RX4R to an RX6R (same receiver basically the 6R just has more PINS). That fixed the constant failsafes.
Changed the ESC protocol from Oneshot to Multishot. Dont know if this made any difference.
Moved the weight of the throttle down from 100% to about 92% to adjust the starting throttle. Then I went into Betaflight and moved the minimum ARM value from the default 1050 to 1100.
Now when I armed the quad the motors would spin right away but so slow that I am able to stop it without much force. This would keep the motors spinning while doing flips and also fixed the flip and roll spaz it was doing before.

Second Flight:

  1. Much better control the entire time.
  2. RSSI stayed at about 92-96 % the entire time in the park.
  3. Got a little over 5 minutes on both a 5S 1300mah and 5S 1800mah.
  4. No hot motors.

Currently working on Improvements:

  1. Get Rescue Mode to work.
  2. Test longer range
  3. Upgrade now to 4.1.1 or later.
  4. Then start to Tune for improved flight times.

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..
