Acrobrat .... How about the Nitrognat?

So, i've been looking for a new 3" build and the Acrobrat seemed to fit the bill. Why not?

The hatchback plate, internal buzzer mount and internal cap mount are my design. Hatchback holds XT60, AXII, and a tail which you can "clamshell" an Immortal T antenna. It uses coarse 1.6MMx9MM screws.

Do you have a hot motor issue with this stack, i have that issues, tried lot of different props and pids but no success, can you please help, or post your pid setting, i am using same setup just motors are different

I experience the same; hot stack , motors, and Lipo ! I've been searching the web but couldn't find a real solution.
Did you ?
Updating Blheli 32 and Betaflight to their latest improved a little but not that much.
My motors are Tmotors 1507 3800KV

Love the color scheme looks A1 how are those motors ive heard they have some durability issues do they hold up in a crash? also does that setup fly like a 5inch?

TheDronanaut   May 13, 2019 

Thanks for the kind words @danbooj. Motors are fair. I did have to replace one with a tree strike. But I hit it pretty hard. It flys fairly well, however the flight times suffer cause of the AUW weight. It's a flying rock with all the TPU :)

Thanks for the info; Im looking at the micro reverb frame from impulse rc and I want to build a 3 inch that flies smooth and has lots of speed should I go with 13xx or 14xx motors?

TheDronanaut   May 14, 2019 

Ohhh that's a tough one. Something like that I would say is personal preference. Thrust to weight is what you wanna look at. It all depends on how heavy the bird is, how much torque you want, and flight time.

Good luck!

how are you able to soft mount the stack? it looks like there is a pin connector for the fc to esc? Wouldnt the soft mounting increase the height too far for the pins to fully engage?

TheDronanaut   Feb 25, 2019 

Sorry I missed your message! The stack soft mounts with grommets at the bottom of the frame. That's the design of the Acrobrat. The stack and lower half is isolated from the upper and the cams.

Damn, that's gorgeous! The details are insane. I'd be afraid to fly it and get it dirty - lol.

Thanks man! It's all about that incentive to not get it dirty :)

how much amps are you pulling, cos do you reckon you could use the 4in1 28a esc from hglrc?

Hey man! Thanks for the kind words! I like the look of shrink tube. I've purchased this brand for the last few years now:

Enjoy and stay tuned! Got my favorite 3" build coming!

Super clean build, fun color choices. Love the hatchback mount, thanks for sharing on Thingiverse. Is the yellow in the photos tape or shrink wrap?

auw weight?

TheDronanaut   Sep 18, 2018 

219g

TheDronanaut   Sep 18, 2018 

329g with the CNHL 850 4s packs.

So, is the limit for FFA registration still 1/2 lb ? If so, this is barely legal w/ no registration? I'm building an Acrobrat right now, but your build is top notch... WOW!

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..
