Really like this micro frame that ticks all the boxes for me : low stack even with Runcam Split mini, top mount battery and most importantly unobstructed HD footage (no props in view), it can take 2inch, 2.5inch and 3inch props.
The frame accomodates two 20x20mm mini stacks (front one for the Runcam Split mini and rear one for the FC & 4-1 ESC).

I used mini/micro version of my favourite quad build components :
Alt Tag

  • CL Racing F4 mini FC
  • T-Motor F15 1106 6000kv motors
  • Spedix GS 25A 4-1 mini 32bit ESC
  • TBS Crossfire Nano Rx
  • TBS Unify 5v VTx
  • Runcam Split mini

Alt Tag
The frame is really small, body is about the same size as swiss army knife, and quite tiny when placed next to my Stingy quad.

I intend to run following props and respective batteries :
Gemfan 2040-3 (CNHL 3S 350mAh)
Gemfan 2540-3 (Dinogy 3S 600mAh)
RotorX 3044-3 (Dinogy 3S 800mAh or Acehe 3S 850mAh)

Alt Tag

The total weight incl. the 350mAh battery is about 150g, or 120g before the battery.

All in all a very versatile micro quad with different prop choices, from tiny whooping to fast moving bullet and with full HD 60fps recording capability.

notes :

  • mounting holes for the two stacks are for M2 screws, this is correct size for the Runcam Split mini, however for the FC & 4-1 ESC that I used M3 mounting holes are required (simply drill out the mounting holes bigger with 3mm drill bit)
  • the CL Racing F4 mini can provide only 800mA through the 5v reg which is "borderline" current for all the 5v components (Unify Pro 5v Vtx, Crossfire Rx and the FC itself), I've therefore used dedicated 5v BEC to power the Vtx separately (it fits nicely between the 4-1 ESC and the FC) and I'm running the Runcam Split mini through the separate 9v pad on the FC
  • CL Racing F4 mini comes with 4 UARTS, 3 of which are non-inverted (UART4 --> Crossfire Rx, UART3 --> Smart Audio, UART6 --> Runcam Split Mini control)
  • the CNHL 3S 350mAh 30C batteries are not that great, I'm unable to pull more than 200mAh out of these, I'll be replacing them with either Tattu 3S 450mAh or Infinity 3S 400mAh batteries (for use with 2inch props)

dumb question i gues but since uart 3 and 4 are fully broken out but u6 only has tx i assume your description above is out and smartaudio is on u6?

pete_oz   13 days ago 

UART6 is also full on this board, the "SAT" pad is actually UART6 Rx. but really doesn't matter what UARTs you use for what, I used UART6 for Runcam control because both of those pads are the side that's near to the runcam board.

brilliant, thanks, good to know. do you find 1106 a bit under powered for 3 inch? what props do you prefer to fly on it?

Can you build me one like this?

A very nice looking quad! 👍

If you don't mind me asking what do you use to color the carbon edges? Looks sharp!

Wow, I never even thought of that! I'll definately have to try those paint markers out! Thanks for the link. That build looks spectacular btw! It's very different from what I build but I love how it turned out.

Any videos? That's a nice looking build.

Available for $361 with coupon toyho at Banggood The Aomway Commander V2s are the 2018 followup to the successful Aomway Commander V1 FPV headset. Unlike their predecessor, which targeted the FatShark Dominator V3s, the Commander V2s have set their sights higher toward the FatShark HD3s. Instead of 16:9 displays with a 32 degree field of view (FOV) the V2s now sport 4:3 displays with an impressive..

The FB 009 is a lightweight and compact budget FPV headset. When I first saw this I thought it might be worth a try. I'm never quite sure which headset to recommend at this price point, so let's see how this stands up. Most notably it includes a USB chargeable 1S 1200mah battery which is a decent capacity for an internal battery. The headset is compact and features a 3" 480x320 16:9 display. The..
