- This is the Tomoquads Kosho build tutorial video.
The kosho is a 64mm brushless tiny whoop on 1s that is a true game changer in this quad class!
I also put in some soldering tips since that was requested by my viewers.
We also take a look at what makes this nano brushless quadcopter stand out above the rest, which is Tomoshimei's floating flight controller design!
I hope this video helps anyone building the Kosho and if you have any questions, please subscribe to the channel and leave a comment.
I will do my best to help you as best I can.
United States based company, TomoQuads, has announced that its newest design named the "Kosho" is now available for preorder.
After extensive testing with different frame sizes and designs, Tomo (Tomoshimei Ki Tata) has finally released his revolutionary Kosho design into the world of nano brushless quads.
The Kosho is a 64mm-sized nano quad that takes advantage of the newly available 16 x16 flight controller created by Fishpepper.
Using a four-in-one esc and powered by revolutionarily small BR0703 brushless motors, the Kosho weighs in with a 32g AUW carrying a 200mah 1S lipo.
This AUW enables the Kosho to produce remarkable power, speed, and agility that has not previously been seen in the brushless 1s platform.
A properly assembled Kosho is extremely stable in the air with little to no drifting, even when flown on angle or horizon auto leveling modes.
These characteristics allow the Kosho to deliver an amazing flight experience for both beginners and experienced tiny whoop pilots that are ready to move into the brushless whoop era.
The remarkable stability of the Kosho comes from Tomoquad's brilliantly designed soft-mount called, "The Floating FC Design."
As many nano quad builders out there can attest, vibration is the number one problem faced in nano quad builds. The motors are mounted too close to the FC, causing the FC's gyro to work extra hard to filter out these unwanted vibrations.
These vibrations are one of the main reasons most nano quads are prone to drift and have decreased flight times.
Until now, with the release of Tomo's Floating FC Design, we have previously only seen so called soft-mount designs that use screws and standoffs, which pass through the frame and flight controller.
Those designs are not effective in filtering the troublesome vibrations.
The Tomoquad's Floating FC Design revolutionizes the mounting of the flight controller, thus protecting it from the vibrations of a nano-sized frame.
Tomo's design filters out all high frequency vibrations produced by the motors and props, thus making the Kosho incredibly stable in the air. This implemental feature gives the Kosho its excellent flight characteristics.

already ordered just waiting for the bits to arrive can't wait to build cheers for the video
I just got my frame, still waiting for electronics and I can go fly :D
this is awesome, like the design of the quad and your video, Im checking the parts list now, christmas is coming :) after building the komodo its time for something new :)
Nice build! What's the final weight of the build, minus the battery? Building a Tomo PredatorX right now. May get this one next! Are the 15000KV good enough or would the 20000KV motors be better?
+cybervid07 the kosho is at 34g AUW complete with prop guards and battery holster and 24g without lipo .Flying without prop guards lowers the weight to a low 19g. 15000kv are fine on it. I havent tried the 20000kv yet. They would no doubt shorten the flight time some in my guess.
Thanks for the info! I take it you are happy with the 15000KV. I have 0703 15000Kv motors already, so will give those a try and get my Kosho kit on order!
No problem thanks for stopping by and watching. I appreciate your support! Sincerely, Dez
I ordered the Kosho! Plan to put the 6A 16x16 4in1 (goo.gl/RER79j or goo.gl/ljIQIP) on it and a 16x16 F3 w/OSD (goo.gl/8wv4OB) on it with 15000Kv motors and run 2S! ;) It's crazy how fast the 16x16 parts are coming now. There's already a 16x16 F4 FC out there goo.gl/QoqtFd, but no OSD, I really like the OSD feature to monitor battery.
cybervid07 Yea the 16x16 FC's are coming out like crazy! 2s on this would be sick!
Got a snapper 7 i want to put the parts on this frame will it work you think
can i use this to transfer my babyhawk parts?
Joseph Gerard Tuvilla , Not with this frame. The Babyhawk uses a 20x20mm flight controller and stand alone escs. Tomoquads does have a frame that would work for a Babyhawk transfer coming out now. Let me double check the specs. If you upgrade the ESCs of the Babyhawk then you can put it on a Tomoquads Mikro 2 frame. Ill double check somethings and write back on here tomorrow. Please subscribe if you havent already done so. Sincerely,Dez
finally got all the part having a bad time with this build tho. two of the motors won't work either when the radio is bound or in betaflight its killing me. how can you calibrated the esc to. build a few quads but this has got me scratching my head
ßF firmware with Dshot does Not use the min_throttle or max_throttle
setting, these are ignored. Just ensure that in the ESCs (BLHeli Suite)
that PPM_MIN_THROTTLE is set to 1000 and PPM_MAX_THROTTLE is set to
2000.
Note: This is not needed in BLHeli_S 16.43 and up since the PPM_MIN & MAX values are not used for Dshot.
This means that when DSHOT is use NO ESC Calibration is required. Just Select DSHOT.
Even though Dshot doesn't use the min/max values in the ESC
(BLHeli) it is recommended to do an ESC cal with one of the Analog
Protocols (OneShot or MultiShot) on new and newly Flashed ESCs. This is
easy to do with the BLHeli Suite's Motor Tab.
What lipo are you using?
My lipo hv 255mah
It is the HV lipo,, The FC doesnt like it above 3.7v,, makes a couple of motors not spin up.. test it by letting it sit till the V comes down. Best flight time is with a 1s 3.7v 380 Tattu. I didn't have any HV lipo's so I didn't run into this issue.
thanks for the information starting to work through it now esc 4 isn't working so that may be the esc board or the signal cable more investigation needed but thanks for the help much appreciated
is it safe to go for 20000kV motor? well maybe it shorten the flying time, but is there any other negatives or positive perhaps between 20000kV and 15000kV with 4amps ESC?
rrawung should be no issue with the 20000kv. They werent released yet when I did the build. Tattu makes a 1s 800mah. Thanks for the comment and if you haven't subscribed please do. I hope the video helps you with your build! It is a Amazing little Tomoquads build! Sincerely Dez
helps alot and thanks for the reply.. appriciate it
another noob question, just to double check, the camera that you are using, is it possible to power it up via bat source pad? what i mean by that is... when its done soldering, there will be a total of TWO joints, ONE at the ESC POSITIVE pad (from POSITIVE Flight Controller and POSITIVE from the camera source) AND SECOND is at the ESC NEGATIVE pad ( from NEGATIVE Flight Controller and NEGATIVE Camera source) correct me if im wrong thanks
The cam I used took 3.3V-5.5V input,, You just need to double check with a volt meter to be on the safe side. That's what i always do. If you don't have a volt meter get one because it will save you a lot of problems.
some says using "Racerstar F3D8 flight controller + Racerstar Star4 4A 4in1 ESC" will encounter problems such as, you cant operate all the motors if your battery is full.. do you encounter such problem? if yes, how do you manage to overcome the problem... appriciate the fast response...
What's the Betaflight Target for the FC?
680production uses the same firmware as the Fishpepper Tinyfish FC. Racestar just copied it. If you look at his site he has all the information on both versions.
Hey man I'm having trouble binding with my qx7,think you can help me out?
I am not familiar with the QX7. I use a Devo 8s with a modded chip that lets me use it with any receiver out there. Is it not binding at all?
desode9 from my understanding it's not, I get no response on betaflight. I might be doing it wrong though
Are you getting a light on the RX when the radio is on? and if you turn off the radio does that light on the quad rx change? If you are bound when you turn the radio off and on with the quad on , you should see a light on the quad change.
desode9 I get a flashing blue light then it turns solid blue. Then I turn off the RX and still get no movement
You using the Racerstar F3D8 16X16mm Micro F3 Flight Control Board Built-in 8CH SBUS Receiver for Frsky X9D Plus?
It's crazy how China will always get the latest designs. After someone designs something here in America there's only one place for it to be made... china lol
+SOLRACHIGH It is really crazy! It is like china has spies everywhere! I have seen Tomoquads designs copied in 2 days and for sale in china. One time they even used a Tomoquads stock photo of the design they stole! Smh. Thanks for watching and for your comment and if you haven't already done so please subscribe. That really helps my channel to promote Tomoquads. Sincerely Dez
