Started with the TomoQuads Katana 2 UL-LR frame that supports front and rear multi-stack for M2 16x16 or M2 20x20 boards and I chose to go with 20x20 as I already had some components laying around but If i was to re-do the build I would rather go with 16x16 not only for weight but as well as form factor as I did have some issues when trying to find space for my capacitor. For my motors I went with the Xnova 1406 4000kv motors which I have used on 3 inch builds in the past and have to say these have been my go to as they are just a powerhouse that will knock your socks off! To power these motors I chose the HAKRC 35A 4 in 1 and the TinyLEDS micro race wire to bring it all together. The flight controller is a AIKON F7 which offered a very nice layout to solder everything on to. As far as fpv goes, I used the HGLRC Forward MT Mini which offers up to 600mw and attached a TBS Triumph pro which brought down the weight a bit as it uses U.Fl connector and is small in size. The HGLRC VTX also has smart audio using Tramp Protocol which in my builds is a must as I hate manually adjusting any VTX. The camera I chose was the Runcam Phoenix 2 JB editon and ended up having to use the Squirt v2 3d printed camera mount set as I did not receive a camera mounting option when I got the frame but according to TomoQuads website the frame is suppost to ship with them included. The Katana frame included a 3d printed gps holder at the rear of the frame which I did not use as I dont plan on going long range with this build but is always a option if your looking for a smaller long range build similar to the Flywoo explorer LR. The dry weight is 174.6g and with a 650 4s with xt60 it turned up (for those who want to be legal) right under the limit at 246.9g. With a 850 4s pack it came in at 285.3g but I think this is the right size for this build. Overall was a fun build and this thing rips and will make parts of your body pucker with every flight!
