Martian 6" Budget Slammed Rebuild

This is a rebuild of my very first 5" quad. Still going with a very budget build, with some simple added bells and whistles (racewire, racelites). I upgraded the old budget motors (racerstar 2205) to the newest budget motors (Samguk 2306 2500kv). I dropped in the cheapo 35A AIO ESC which has worked well for me on my other 5" build so far. I have the 6" arms on this for some prop flexibility and clean air flow. I'll probably fly it on 5"-5.5", but I might experiment a bit with 6" too. Maybe too high KV for 6"? Not sure, will experiment. I also managed to slam the frame down to 20mm which I like quite a lot. Using the new Frsky X-lite with it (normally use Spektrum). I feel like my builds are getting a bit cleaner and more tidy which makes me feel good inside. XD

Which arm size did you use for 6", the 255mm arms? Which "standoff width" option did you use for the Micro FPV Cam Mount? Also, when you slammed it, did you just not use the X braces in the front and only use the standoffs, or did you add something else? Thx!

cutthenoise   Jan 28, 2019 

Yes, 255mm arms. I don't remember the standoff width. I think I measured it. If I understand your question correctly, I just used the standoffs and didn't use the other braces (too tall.)

Zzyzx   Jan 28, 2019 

Cool, thanks. Yeah, sorry I wasn't asking about the standoff width, I figured they were standard standoffs. Just curious if it was OK to leave the carbon fiber side braces off, seems like it was. Looks cool slammed, and at the current prices, a real bargain frame. Thx!

how did you mount the FC?

cutthenoise   Jun 15, 2018 

I used a 3D printed TPU mount that allows you to mount a 20x20 board on a 30x30 stack. I got it from catalyst machineworks.

What battery do you use??? how many calls and how many mahs and what brand.

cutthenoise   Jun 14, 2018 

I have some Tattu that are 1300mah 4S. And I recently got some 1500mah 4S CNHL that I like too.

Whiffles   Jun 07, 2018  

Nice job! Are those 20mm standoffs?

cutthenoise   Jun 08, 2018 

Thanks! Yes indeed. Loving it slammed.

Whiffles   Jun 08, 2018 

It's the best way to go with the Martian!

cutthenoise   Jun 08, 2018 

Yes agreed!

cutthenoise   Jun 08, 2018 

Thanks! Yeah I'm pretty happy with it.

cutthenoise   Jun 08, 2018 

It is antenna only, but from Brain3D. Gopro mount is rom Brain3D too. Good stuff there.

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..
