6S Monster Marmotte
By CiggyTardust on Jul 12, 2019
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.

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

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

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..

what did you use to end off the cable sleeves? heat shrink?
Yes sir
nice! one more queston, with your parts was the mamba's manuel on what to solder where accurate? also if i were to use the same setup, would i need to buy spacers for the stack?
It's been a couple months but I did use the wiring diagram on the Diatone website when soldering everything up and it worked fine. It comes with spacers but I used my own anti-vibe ones.
thank you, I've been looking for parts to build my first quad and have been thinking about using a lot of your parts, just with 4s motors. thanks for the inspiration!
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?
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.
