Hmm, if you want to put a servo on your light to make it like a searchlight then you will used up all of the ch, beside that, i don't know how to convert pwm pulse into an on/off switch, but that is a good idea, my transmitter also have 1 unused ch, maybe i'm gonna do a little research, and if i...

The flight controler is put under the small top cover, and the receiver is just behind it, I use a 1/2" tubes, it was a tail of a helicopter heheheh, i bought it at my local hobby shop for $9 each. The gap between the top and bottom plate is 16mm And yes, i use a 3mm mdf board. If you can find a...

Btw this is mine after all the elctronics put together

Yup, mine was 500mm, from motor to motor diagonaly So the radius from the center is 250mm

According to ecalc that GJH105775 mention earlier, you will have about 6 to 9 minutes of flight time, i am not recomend using 4s battery if you will be using props that 10" and bigger. Maybe increasing the mAh will yield a better result

If you are not planning to mount a gopro and gimbal, i think your setup will be just fine, even if someday you decide to add an action cam and gimbal, i think it still be okay, just a slight reduce of the flight time

Just waiting for the props to arrive

I salvage it from someone else crashed frame heheheh, he sold it for Idr 100.000 (about us$ 8). It already had holes to mount a gopro gimbal, so it is quite a bargain lol

But if you have the resource and the material, definitely go for carbon fiber heheheheh but fiberglass composite panel is also good

Yup, but that is the max amount, usually it was less than that, depends of what kind of props u will be using. I was using a 3mm mdf board and a 1/2" carbon tube as reinforce material, i use a lasercutter to cut the mdf. The reason i use mdf board because it was cheap. It was not the lightest...

From my research when i was planning to build my first quad, i was googling about the type of motors that i can use, but i forgot where i read the data from, but it says that usualy the maximum amount of lift a motor can generate is 4 times the amount of watts it require. So if a motor used...

If i'm not mistaken, the amount of thrust is usually 4 times the power(watss) in grams using the recomended props. The motor pull 210watts each, so each motor can lift about 800grams max. In total u will have approx 3200 grams of thrust from the 4 motors. So the total weight of the quad would be...

If u are already buying 10" props then i think the frame would be 350mm to 550mm. Depending on what material u will be using. Bigger frame usually give more stability when smaller frame usually more agile. The bigger the frame the more heavy it get. Do u have the data about the motors? On how...

If u want, i can email u the coreldraw files heheheh, feel free to tinker with it

What kind of frame do you want to put the parts into? Coz u can't put a big battery into small frame and a small battery is pointless in bigger frame. If u planning to use 300-450mm size frame, i guess a 2200mAh and minimal 40c in 3s config will be enough I,m using a 5400mAh 45c 3s battery for...

Didn't have time to measure the weight yet, but i estimate about 200-300grams, maybe less

That is a picture heheheh, yeah this one is much more stiffer than the first one, and the arm didn't flex at all

A lot of my local hobbyshop only sells parts for plane and helis, but not for multirotor, so it's a bit difficult to find reversed props. But some of the online store have them, i just try my luck with the 10x55 carbon prop first heheheh. Btw this is the new frame design

Hahaha, it will take 3 weeks to order from hobbyking to my country, maybe i will look for another prop alternative, maybe some of the local hobbyshop have that 10x6 wooden prop, but are they available in cw and ccw configuration?

The motor is suppo 28-14/6 1400KV, it has 400watts of power and 50amps esc. I use a 5400mah 3s 45C lippo battery
