Anyone built Quadrotor / Tricopter?

I was wondering if anyone else had built a tricopter or quadrotor? Got some parts lying around for it but its well down on my TODO list. Was wondering if anyone else had played with one.

ive been tempted to get the control board from hobby king http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=17537

For the price seams like a decent low cost option for a basic accelerometer setup with a built in micro. AVR on board with ISP so easy to customise and play with. Would probably get one of their cheap frames initially as well.

All in all very tempting to do this with cheap FPV goggles setup from HK siilar to what looks to be now discontinued http://www.hobbyking.com/hobbyking/store/__14538__Turnigy_BASIC_FPV_Goggles_320_x_240_4_3.html and one of the cheap camera transmitter setups

For a cheap probably around $200 or a little more autonomous quadcopter with FPV

I have been playing with a MultiWii setup for several months but didn't have an airframe until today. I have a V2 Paris board from www.multiwiicopter.com with a clone wii+ and a analog accelerometer that the pick-and-place machine rejected at my old job. I have been playing around with a custom V1.7 firmware and bluetooth serial adapter to adjust setting using the android app. I have been meaning to get the V1.8 firmware going but I had to change jobs so have been busy.
I have been slowly raising funds for the rest of the parts but its a low priority. Thanks for some xmas pressies I am almost ready to get airborne. just need some mounting hardware, props and battery. Some higher rated BESCs would be nice too. The trouble is I need 4 of everything.
The hobby king board is a direct copy of the KKopter board. It is a very nice, basic setup but lacks the customisation that the MultIWii allows. It uses 3 gyros from the HK401b and no accelerometers. no auto leveling just stabilizing.

Not flying yet, just a few hops. I'm waiting for a new battery.

I'd certainly like to build one - there is still too much on my to-do list though. One question: Does anyone know why there are no quadcopters built using ducted fans meant for EDF planes? They are much more efficient than the open blades normally used and I saw a video of an expensive industrial quad that had EDF-like cowls around the blades for better lift. The only reason I could think of was the noise.

I think this may answer the question and more Razz


Flies good. Smile

EDIT: ok, it's not actually ducted fan. My bad... Embarassed Embarassed Embarassed

LOL still a good video. I just researched the question and EDFs work but are very inefficient for a quadcopter design. apparently, the regular copter blades with a small cowl around them are a good compromise.

Yeh the extra weight for Quads probably offsets the increase in efficiency from cowl.

Cowls are usually only on Quads to stop blades running into people or things.

Electric Ducted Fan units have been used before but give poor control and require relatively large amount of power to fly.
EDF units are designed to move small volumes of air at high speeds. For a multi-rotor aircraft you want to move large volumes of air at low speeds. Ideally you want a low Kv motor turning a large diameter / large pitch prop.
There is a difference between a cowling and a duct. a duct simply guides airflow while a cowl is designed to produce secondary lift as air flows over and into it.

A very old thread, but this is exactly what I am building next.

How successful was everyone that built one? Did you get any FPV going? Any tips for a newbie? Smile

Cheers,
Mark
