I am looking to get into quadcopter construction and control with a couple of friends of mine. I'm an electrical/controls engineer with microcontroller and control loops experience, my brother is a mechanical engineer in product design and our buddy is a computer scientist. Will we benefit from our degrees/experience constructing our own frame, or are a quadcopter design too specific? Or is it really a choice whether to have fun learning, or have fun flying as soon as possible?
We have one kit in particular we're interested in.
My reasons for buying a kit is this:
Of course depending on how much we would be building from scratch, isn't this the parts I would roughly end up with anyways? I mean, I'm not gonna extrude my own square tubing or wind my own motors anyways.
Someone else might have bought the same, thinking this could give the community the advantage of sharing experience with others. In the beginning, this might only benefit us, though!
Spare parts, of course.
Now on to the specifics of this kit. These are the individual parts
Control board (to be thrown out eventually) http://www.goodluckbuy.com/kkmulticopter.html
Motors, I think (55g) http://www.goodluckbuy.com/sunnysky-x2212-brushless-motor-kv980-for...
Shaft adapters http://www.goodluckbuy.com/3-17mm-plane-fixed-pitch-propeller-adapt...
Propeller (7g) http://www.goodluckbuy.com/gws-1060-10x6-3-blade-propeller-cw-4-pac...
ESC (19g) http://www.goodluckbuy.com/hobbywing-skywalker-20a-build-in-bec-2a-...
Connector board ESC/battery (6g) http://www.goodluckbuy.com/multicopter-multi-tri-copter-power-batte...
The setup so far is 55gx4 + 7g*4 + 19g*4 + 6g = 300g + frame + shaft adapters + homebrew PCB (rc receiver at first) + battery.
Is this starting to weigh too much? It's a shame there's no weight spec. on the frame.
Was hoping not to slice too much off of the battery size...
Main questions: Do you see any main concerns that we don't with our untrained eyes?
We are really looking forward to start on this project!
Looks fine, frame looks to be a well designed standard quad frame. Definitively nothing to say about the price. Just make sure you purchase spare parts (if you do not want to make your own). Experimental quads crash... a lot. It is part of the fun.
I would buy one from the online store here or jdrones. Alot of support, etc, etc, etc.
Thank you for your feedback.
Is anyone here familiar with the motor XXD 2212? Flight time is not very important at first, so in practical means I guess the smaller battery the better, but of course I want it to take off at least before the batteries are dead.
It's not that I wouldn't want to buy from this store. It's several things attracting us to this kit. First is price, second is shipping price (free) and last is the included controller board which makes it easy to test electrical connections and stuff before I throw the whole board out and start buying IMUs. And, it includes a cheap AVR programmer, can't get enough of them for the hackerspace!
