Yup, i think a 450 is too small for the kind of stuff you will put into it, for a 1,6kg body, you'll gonna need at least 3,5kg of thrust. I don't think the motors will provide that much thrust. How much flight time did you expect? If you want to put that much stuff, at least you'll need a 600...

Be careful with the holes in the arms, in my experience, the holes is a bit too long, it compromise the stiffnes of the arms , i think it better with short holes but with 3 or 4 pairs per arm

Yeah, it's bad hahahaha, its about from 30feet high, almost crash to my neigbour wall, still have't used to the controls

Have another crash today hahahahaha, not because a design flaw, but because of my clumsyness. Fly too close to a wall, and in a panic i flick the throtle. Snap one of the carbon tube arm.... But i know now that the design works. I guess i have to tune the throtle sensitivity, it hover just with...

In my opinion, it would be alright, jakson has show some example at the previous page, the quad with the wooden arm, it doesn't use symetrical arm between the 2 front motor and the 2 rear motor. As long as the left side motor is a mirror image of the right side

Heheheheh, sorry if i'm confusing you, try to google wiring diagram for quadcopter, maybe it wil shed some light

Hahahha, yeah i know, thats why it was a long term goal, right now an action cam will have to suffice. So someday i can build a multirotor that can carry those equipment with minimum risk heheheh

Yup, i agree, it comes back to the builder preferences, i own a company that uses lasercutter to make acrylic products, so my first choice is lasercut, but i totally understand that not everyone have access to fancy tool. My goal was to build a multirotor that can carry heavy camera equipment...

Hahaha, it's ok, just glad i can help, btw when you connect the esc to the flight controler, just make sure only one esc is supplying power to it, disconect the + cable from the other 3 esc. Only the ground and the signal cable is conected to teh FC

It was the same epoxy resin used to make fiberglass composites, i bought it from a local chemical store

Done

If u like, i can email the coreldraw file, feel free to modify it,

Heheheh, i'm still gonna tinker with the design, still waiting the result of the next flight, but noted, as soon as the frame take flight, i'm gonna post it there

Bec is a battery elimination circuit, i t is used to power the reciver and the FC. Usually the reciver got it's power from the built in bec inside the esc, but my esc is an opto esc, it doesn't have a built in bec so i have to use a standalone bec. Yup, a distribution board is a verybgood idea...

Sure, the cc3d flight controller is the little square box, the one under the middle cover is a standalone BEC, and i put the receiver at the back to balance the weight from the gimbal and the action cam

As soon as this baby fly, i'm gonna post some videos heheheh

Yep, the motor mount is between the motor and the mdf arm

Yeah, actually this is the 2nd frame i build, the first one had a design flaw, the wotor mount is not attached to the center plate, but only to the carbon tube, so if i'm not calibrate it right, the anglenof thrust is different at each arm. The first frame, i glazed the mdf with an epoxy resin...

There is one option that a servo can be use to flick a switch heheheh

It was 16cm x 16cm. Hehehe, let me know if you find a way to make 1 ch as an on/off switch
