I tried this last year here as a budget build with a 20x20 stack but kept burning up the ESC with the high current draw of the weaker DYS motors. With a bulletproof ESC the motors should be the weak point then. Better motors purchased in anticipation of this and proven on the 4th pack (read below) So go big, or go home! Well I wasn’t going home! The Bits: Frame- Strix Screech-R (v1) FC- T-Motor F7 ESC- T-Motor F55A ProII F3 Motors- DYS Shu 2306 2800kv (BURNT) T-Motor BMS Racing Raptor 2207.5 2700kv Rx- FrSky XM+ Cam- Foxeer Razer Micro VTx- Eachine VTX03 Ant.- O.R.T MicroVee Stack seems huge compared to the tiny 20x20 I was used to seeing in this frame lol I was never a fan of the original TPU cam mounts that came with the frame so I designed and printed my own for a better fit. I have also had these RaceLiteWires laying around so I decided against going as ultralight as possible and designed a TPU mount for those as well. If you can’t look cool, it’s not worth doing! Had to take a break and prepare for Zombieland Everything coming together. Why not have LEDs on the bottom too I have now added NOS to all my quads Designed a mount to secure the power wires with a zip-tie She flew amazing until the forth pack. I decided to push it with several high speed passes and one of the DYS motors failed. Slinging solder everywhere! Even on the standoff Here’s the LOS footage when the motor failed. Love the sound it makes too! I will add some DVR footage as well when I get around to uploading it New BMS motors are installed and waiting to be tested. Coming soon! Stay tuned! EDIT: Added maiden DVR footage.

We will see how the 1300mah packs sag, but so far I have only used the 1500mah.

I updated the FC to BF 4.1 as well. My base tune didn’t seem too fond of the 6” props but felt great on 5”. So I need a day to get out and play with the 4.1 filter settings and get the 6” props locked in better. +1 from me on doing a lightweight 6” I am loving it so far and haven’t even really had much time with it in the air Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 It took a little while to figure out my filter setup as the harmonics are quite a bit different from most typical 5” builds. But once I got them all sorted and figured some things out in Betaflight 4.1 she has been performing great. Here is the first full flight after setting the filters. She gets pretty well tuned in during the session after this. Video coming soon!!!

Also made it into a DVR comparison video Posts: 5,903 Threads: 47 Likes Received: 2,785 in 2,247 posts Likes Given: 7,684 Joined: Jul 2019 Reputation: 97 Nice looking build. What is NOS (in cars, NOS is Nitrous Oxide injected with the fuel), but these quads are electric. Please explain what you have here? Thanks.

The poser ;-) The ground is for dead people.

I put NOS bottles on all of my fleet as I am a motor-head at heart. I put a can of Redbull on my fly buddies quad. As he is always pushing the envelope There are several types to choose from at RDQ. https://www.racedayquads.com/search?q=va...pe=product Posts: 5,903 Threads: 47 Likes Received: 2,785 in 2,247 posts Likes Given: 7,684 Joined: Jul 2019 Reputation: 97 (21-May-2020, 03:59 PM)Drone0fPrey Wrote: yeah it’s a fun sticker to add to your capacitors.

Yeah, I was a gear head back in the day...when speeding was just speeding and street racing was popular and wouldn't necessarily land you in jail. I am much more relaxed now that I am old and retired; but still like a good muscle car or street rod. The new craze is "rat rods", but too old to get into that.
