6S Monster Marmotte

After three years off from the hobby, I decided to build a 6S Marmotte. I used to build professionally for Armattan in Taiwan and I'm personal friends with Chris, the owner, so frame choice was easy. It's interesting to see how far components and frame design have come in three short years. Overall the build was a pleasure to complete. I chose the Xing 2208 motors for their reputed power and smoothness... I haven't been disappointed. The Mamba F405 stack has performed flawlessly so far. Maiden flights went off without a hitch and the video was crystal clear thanks to wiring the camera from the VTX and installing a 1000uf capacitor. I love how clean this build came out. This thing SCREAMS, not sure if it's actually louder than my old 4S rigs or maybe I just remember them being a bit quieter. The only issue I really ran into with this build was finding the right hardware to mount the Mamba Stack in the Marmotte while still clearing the top plate. I settled on the purple aluminum spacers you see, time will tell if that was a wise choice or not. Edit: ended up switching to soft-mount hardware from iFlight and it works great.

what did you use to end off the cable sleeves? heat shrink?

I'd definitely go with a different stack... something with BLHeli32 ESCs for RPM filtering and other features. F4 or F7 no big difference though.

what do you not like about this one? are there any budget stacks you can recommend?

CiggyTardust   Oct 31, 2019 

I'd go with BLHeli32 ESCs for RPM filtering and autotiming capability. This stack is BLHeli S. It's worth the extra $30 bucks or so for future proofing. I got the Mamba F722S Mini stack on another build for $55 on sale at BG but regular price is around $80. There are iFlight stacks that are cheaper as well.

Nice clean build and nice backpack! 511?

CiggyTardust   Sep 02, 2019 

Thanks. The backpack is one I got off Amazon, forget the brand

Rad, I need to find a backpack like that to carry my quads!

Are you still having hot motors, I'm running the xing 2208 1800kv on one marmotte and xing 2207 1800kv on the other. I'm on the TX gulf coast, it was 98° Friday when I did my maiden, and I could hold a lip to my motors right after landing. Let me know if I can help you get the heat down. I did make some pid changes on 4.0.4. My build info https://rotorbuilds.com/build/19342

Hey man, yes I still have the issue unfortunately. I appreciate your willingness to help! I just got done moving to a new house so I'm a bit swamped with that but plan to continue troubleshooting in the next few weeks. What kind of PID changes did you make and did they help with motor temp?

Great build nice and clean. Wondering how you keep the motor wires in the cable from moving side to side?

CiggyTardust   Jul 19, 2019 

You mean the cable sleeves? They stay in place as there isn't really enough slack for them to move anywhere. I had them zip-tied down for a while but it didn't seem necessary.

Yeah... that looks... like you used to build quads for a living! Very clean work I must say. Do you have very small fingers and very good eyesite? I have just the opposite, so I use magnifiers... and hemostats. =]

CiggyTardust   Jul 17, 2019 

Thanks man! I enjoy building as much as flying. From planning the layout to cleaning everything up... it's very satisfying when it all comes together. And no, my fingers aren't particularly small, I'm just a bit OCD at times :)

HK-AERIAL VTOL   Jul 17, 2019 

Yeah.... I agree. It rains here a lot and so if you are gonna be into quads you should like to mock up (a thousand times) and solder (hopefully just once).

very nice build!

CiggyTardust   Jul 17, 2019 

Thanks man! I see you're running those monster 2208 motors too on your build. How ya liking em? What's your AUW?

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..
