Intro:  250 quadcopter, full builda homemade 250 size quadcopter is not difficult to build. it just takes a bit of time to find and get he necessary components. The following components have been used inthis project:

4 motors, 2206-2150kv, baby beast, hobbyking4 esc's, 12 amps, afro1 receiver, frsky tfr61 flight controller, naze32, flashed with cleanflight1 analog video transmitter with antenna, immersionrc1 fpv camera, cmos mini, hobbyking1 hd camera, mobius1 lipo alarm1 power distribution cable, hobbyking1 lipo battery, 1400 mah1 "dirty" frame, laser cut from 6 mm poplar plywood1 "clean" frame bottom, laser cut from 2 mm birch plywood1 "clean" frame top, laser cut from 2mm birch plywood2 motor mounts top, motors 1 and 3, 3d printed2 motor mounts top, motors 2 and 4, 3d printed2 motor mounts bottom, motors 1 and 3, 3d printed2 motor mounts bottom, motors 2 and 4, 3d printed6 vibration damping ball, 80 g, hobbyking6 hex spacers, 29 mm, hobbyking12 bolts, m3 x 6 mm12 bolts, m3 x 20 mm (3 per motor is enough)4 bolts, m3 x 16 (nylon)8 nuts, m3 (nylon)4 lock nuts, m44 propellers, 50301 alpha gel, 30 x 30 x 51 alpha gel, 60 x 20 x 52 velcro strapslots of zip ties

Step 1: Laser cut frame partsthe base frame has to be cut from 6 mm poplar plywood. the remaining frame parts are cut from 2 mm birch plywood. if you don't have a laser cutting machine just printout the plans, glue them to the plywood and cut the frame parts with a fretsaw or a scroll saw.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 2: Glue adaptors to base framethe 2 mm adaptors for the vibration isolator are glued to the base frame. this is necessary because the vibration isolator do not fit the 6 mm thick plywood.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 3: Paint frame partspaint all frame parts so they are water-resistant. i like to use acrylic paint because the paint roller can be cleaned very easily with water.

Step 4: 3d print motor mountsto improve flight stability angled motor mounts are supposedly helpful. they are not a requirement and some might even dispute their effectiveness. but they can be madevery easily by everyone who has access to a 3d printer.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 5: Attach prop adaptorsattach the prop mounts to the motors. in order to keep the bolts from loosening under the vibrations of the motors i always use a thread locker similar to loctite.

Step 6: Mount rubber vibration isolatorsmount the rubber vibration isolators to the base frame (the dirty side, i.e. the side with the vibrations from the motors). i don't use any glue to secure them, they are justheld in place by a form fit.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 7: Attach motors to base frameeach motor is bolted to the base frame with three (to save the weight of the fourth) m3x20 bolts and the two pieces of the motor mounts. care must be taken whenorienting the motor mounts. the motor must be slanted towards the center of the base frame.

Step 8: Connect esc's and attach to base frame with zip tieseach esc's three adjacent connectors are connected to a motor. at this moment the rotation direction of the motors is arbitrary. this has to be checked later, when theflight controller is being configured. the esc's are fastened to the base frame with zip ties through the predrilled holes.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 9: Install power distribution cablethe power distribution cable is connected to each esc and attached to the frame with a zip tie. the power cable of an immersion rc video transmitter can be directlyplugged to a special connector of the power distribution cable.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 10: Bolt flight controller to "clean" framethe naze32 acro flight controller is bolted to the lower plate of the clean side of the frame with nylon bolts.

Step 11: Install fpv camerathe tiny fpv camera is attached to the frame with a zip tie. better check the orientation of the camera first.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 12: Connect receiverthe naze32 comes with a wire harness than makes it easy to connect it to the receiver.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 13: Bolt hex spacers to frame, attach velcrosthe six hex spacers are bolted to the lower plate of the clean frame with m3x6 bolts.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 14: Attach analog transmitter with zip tiesmount the antenna to the video transmitter and fix the transmitter to the upper plate of the clean frame.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 15: Prepare esc's and connect to flight controllerremove the red wire from the jst connectors of three esc's. this might not be necessary for esc's with a linear bec. i would do it anyway. the wire can be removed by liftingthe little tab of the plastic connector casing while pulling on the cable. the freed connector has to be isolated with tape.

the connectors are then connected to the flight controller. see the naze32 documentation for detailed information.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 16: Connect flight controller to computer, check motor rotationinstall the cleanflight configuration software and connect the flight controller to the computer via a micro usb cable. the configuration software allows calibration of theesc's. additionally the rotation directions of the motors has to be checked. the rotation direction for a quadcopter is described in the naze32 documentation.

in case the rotation direction of a motor is found to be incorrect, simply swap two wires to the motor.

once the motor rotations are set, the bottom plate of the clean frame is connected with the bottom plate of the dirty frame with the rubber vibration isolators. this can betricky but a pair of pliers and a screw driver help a lot.

Step 17: Conect camera and transmitterconnect the camera and the power supply to the video transmitter.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 18: Tidy up cabling mess, attach top platethere are lots and lots of cables from esc's, video and others that need to be secured away from the propellers. more zip ties and tape can be very helpful...

bolt the top plate of the clean frame to the bottom part.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 19: Mount propsmount a prop with correct rotation direction to each motor. in case all prop adapter have a right-hand thread use lock nuts to avoid loosing propellers in mid-air.

http://www.instructables.com/id/250-quadcopter-full-build/

Step 20: Install mobius, lipo and lipo alarmstrap the mobius camera to the top plate with a velcro strap. the separation of the dirty and the clean frame with vibration isolator eliminates already some vibration fromthe motors. alpha gel around the mobius camera reduces vibration further.

Step 21: Done!finally, we are done. charge your batteries and let's go test fly!

Step 22: The fileshere you find the stl-files for 3d printing, pdf and corel files for laser cutting and the full 3d model for creo elements express (free cad software from ptc).

 muellerr.ch says:  Mar 15, 2015. 1:26 PM  REPLYWhy even bother buying a $16 frame when you can watch flight videos on youtube for free?

I thought instructables is about creating things...

 nvasilev1 says:  Mar 15, 2015. 2:24 PM  REPLYThere enought creativity to be applyed in building the quad, but I appologize did not mean to undermine the instructable

 EmmanuelC3 says:  Mar 16, 2015. 9:41 AM  REPLYI appreciate your link. Im just getting into this so $16 to have a backup frame is perfect for me.

 faelenor says:  Mar 16, 2015. 4:36 AM  REPLYYeah, but not everyone has access to a laser cutter and 3D printer!

 cyberdove says:  Mar 15, 2015. 4:37 AM  REPLYYou're a fast worker. Want a job?

 muellerr.ch says:  Mar 15, 2015. 1:13 PM  REPLYI know and I could have done it even faster :-)

 nvasilev1 says:  Mar 15, 2015. 7:12 AM  REPLYNext step learn to fly https://www.youtube.com/watch?v=1MBW8zoZUR4

 infinity.rps says:  Mar 14, 2015. 8:42 PM  REPLYwhat controls/sensors are used for the flight ? please elaborate . can Arduino uno be used for the flight controller ? if yes then how to make it ?

 muellerr.ch says:  Mar 14, 2015. 11:26 PM  REPLYI use a naze32 flight controller board which has all the necessary sensors built in. The firmware used is Cleanflight. You could as well use an arduinobased flight controller. More information here:

http://www.multiwii.com/

I've used the multiwii's a lot in the past. But now I switched to the naze32 since it's so much easier to configure.

 Electronics Circuits says:  Mar 12, 2015. 9:59 AM  REPLYIs it possible upload the 3D models? Love to make one.

 muellerr.ch says:  Mar 12, 2015. 10:44 AM  REPLYHave you looked at step 22? That's where all the files are. Otherwise you can find them here:

 Electronics Circuits says:  Mar 13, 2015. 7:20 PM  REPLYThanks. Can't believe I missed that :) . Maybe the page didn't load fully.

 sudu18 says:  Mar 12, 2015. 7:24 PM  REPLYwhat program is used in your quadcopter?

 muellerr.ch says:  Mar 12, 2015. 9:19 PM  REPLYI use cleanflight.

 Blue Hawaii says:  Mar 12, 2015. 9:26 AM  REPLYGreat build. Try using a Neutral Density filter on the Mobius. That has helped me avoid the jello effect.

 muellerr.ch says:  Mar 12, 2015. 10:43 AM  REPLYI've never tried that on the mobius but on my gopro. Fast transitions tended to be blurry though and on my 250 quadcopters flying is a constant fasttransitioning...

 sudu18 says:  Mar 12, 2015. 9:21 AM  REPLYwith what you control the quadcopter?phone or PC?

 muellerr.ch says:  Mar 12, 2015. 10:40 AM  REPLYI use my standard rc controller from futaba (t8fg). But there are cheaper options like the taranis from frsky or the orangerx transmitter from hobbyking.

 VikramA2 says:  Mar 11, 2015. 10:39 AM  REPLYvery nice quadcopter !

is it possible for you to please send the laser cut frames and 3D printed parts now ?

 muellerr.ch says:  Mar 11, 2015. 12:30 PM  REPLYthank you for your interest. I'm sorry but I cannot provide finished parts.

 VikramA2 says:  Mar 11, 2015. 10:02 PM  REPLYI think you have mistaken meSorryI was actually asking for the digital cut outs of the laser cut wood and for the 3D printed parts , as I am not sure with the measurements of the parts .Thank you

 muellerr.ch says:  Mar 10, 2015. 9:35 PM  REPLYI did upload 2d files from corel draw (.cdr + .pdf files) and also the entire cad model from creo elements express. I don't know why they don't show up.

 urmit says:  Mar 11, 2015. 10:38 AM  REPLYI do not see them either... and would like to use them. thank you for sharing!

 slash359 says:  Mar 10, 2015. 3:32 PM  REPLYLike the clean and dirty setup

 muellerr.ch says:  Mar 10, 2015. 9:51 PM  REPLYI've tried without the clean/dirty separation before but I always had a slight jello effect in the videos from the mobius camera, no matter how well theprops were balanced. I blame it on the motors that are a bit cheap and hard to balance.

 craftguy says:  Mar 10, 2015. 5:26 PM  REPLYAbout how much did all of this cost?

 muellerr.ch says:  Mar 10, 2015. 9:47 PM  REPLYwithout fpv system and camera the quad cost me around $180 ($100 motors and esc's, $30 flight controller, $20 receiver, $12 lipo battery, $4 lipo alarm,$4 vibration damping balls, $4 aluminum hex spacers).

the mobius camera was around $70 and the fpv system on the quad was about $80 ($30 fpv camera, $50 immersionrc 25mw transmitter).

this sums up to a total of $330.

 tomatoskins says:  Mar 10, 2015. 1:44 PM  REPLYThat looks absolutely amazing! I'd love to see a video of it flying. I've always wanted a quadcopter, maybe I'll just need to sit down and get everything forthis!

 muellerr.ch says:  Mar 10, 2015. 9:32 PM  REPLYThanks. I'm working on the video.
