h-copter that has evolved from my previous V1 and V2 design, see my previous uploads.
this one in the next step up, based around a 12mm (actually measures 13mm) aluminium SHS frame and a DJI Naza flight control - but this can be adapted to suit your own choice of controller.
previous versions used Hextronik DT750 motors, this version is designed around NTM series 28 motors. if you want to use the DT750 motors, then download the motor mounts from my h-copter v1 (i still update these hcopters now and then, if i think the update is of benefit) see my previous build and flights videos on my youtube channel called "intensewalkera"
there are playlists there for the build in sequence, they have changed slightly but you will get the idea of how it all goes together.


i always print my stuff at higher infil, 0.2 height 75% infil on main parts, motor mounts at %100 infil ,battery tray and top panel under battery tray %75, other top cover pieces and exhaust at
you can probably lower the infil % but but but, ive no idea how it will hold up, so use these figures as a guide, i am slowly lowering the infil rate to see how it goes.
first test flight see here http://youtu.be/M4j5dbzkWm4
this flight was just a shakedown and it was using the dt750 motors, it is currently using NTM series 28.

i have a gopro mount, which i am still fine tuning and testing, that works with this quad and i will upload the files and things required to get it working once i have figured a few things out

i still think i can get a better design of this and i am sure V4 will be along later, all the previous designs fly great,i am just trying to make the layout better, the COG better, the dynamics better, the build better, the camera mounts better etc etc, so each time i destroy one i just build a newer version that incorporates better logic and design.

Excellent build. very stable. nice colors

Do you think a landing gear can take the blow during crashes and avoid breaking the frame or aluminum tubes?

i think some sacrificial landing feet held on with zipties maybe worth looking at, more so for you if you are just getting into quadcopters, all my crashes tend to be monster downs where landing feet wouldnt help anyway, they would be simple to add, but they would have to be attached to the aluminium, which in turn maybe damaged (bent) in a heavy landing. if people want some landing legs, i can easy knock some up, but someone will have to test them! i have considered some glue on feet, that will go on the mainbody and not the aluminium, i could do both options for people to decide.

What if the landing gears were attached to the bottom of the main body? Since AL tube seems to be a premium in the US, I am thinking in terms of replaceab landing gear thar can be printed again easily

Very nice! Awesome.

That is really cool, I noticed the flite test guys on later videos have put landing gear on and are mounting the lipo underneath. You could design a really cool landing gear / under carage battery holder.

I have looks at the landing gear option and they would be very easy to retro add, but I like the flat base for landing on, you can land it on uneven ground, it never tips and I think PLA made landing gear will not be strong enough and will snap over a period of time. I am not keen on the battery being exposed on the bottom of my quads , it's a high value item, however it would make a lower and better COG, this h copter allows for plenty of variations and options.
