Hello pilots! I am new and want to build my first quad copter, but I am not sure about the ESC, Motor, Propeller on my part list. I also do not know which battery pack and battery charger I need to fly between 10 and 20 minutes with my setup. Please give me advise about the parts, if you think there is a better alternative. Thank you!!

HI mate the motors add some weight to the quad i have them on mine you may want to look at 10x4.7 blades for better lift carbon fibre blades are better if you can get them genfan does them if you fly hard the plastic blades get stress fractures and snap i know i had 3 fail in one flight and blade 4 was showing signs of a snap coming they had done 50 flights
have you got you heart set on the multi wii your need a pc to set up the kk2 board has led display so you can adjust at any time and is a really nice fcb
the 450 with pcb built in is great so you dont need power harness
i run 2200mah 50/90c buts thats over kill..... 2200mah 20/30c will be just as good runs my 450 quad and 450 heli on them they just get warm so thats fine
transmitter is a good price you only need 4 ch for a quad but that good as you can fly more on it later
Battery alarm is a good buy if you dont have a timer on the transmitter
as you are using hobby king this is a good buyhttp://www.hobbyking.com/hobbyking/store/__7028__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories.html

Now ESC ok here goes there ESC and there are mutlicopter optimized ESC pay out a bit more for simonk flashed ESC they are flashed just for multirotor
now watch this video and your see what i mean i would go for a 30amp esc going over kill on this is agood thing you dont want one to blow out
if you go for kk2 it has its set up manual built in so this will help you set up esc motors props self leveling etc and if you go for simonk flashed esc you wont need program card so you save money on these parts so you can spend a bit more on others
i must say its a good list for you first time some thing else to think about is lights on the arms red on back white on front help you see what why round you are even when its 90 feet up and you can do night flying now thats fun happy flying mate if you need help e -mail me holtneil@hotmail.co.uki forgot to say try this site for set ups you can put in your info and it will tell you if it will work

Thank you very much for your reply. I like the Multiwii pro 2.0 because of all the built in options like, e.g. GPS, go home, track flight height, speed location etc. The price is also good. The KK2 looks really nice and easy, except it does not have built in options like the Multiwii. Thanks for pointing me out the power supply for the charger, I did not realize it needed a power supply. I will look into the simonk ESC and the 10x4.7 carbon propellers. Will the big propeller be good for the motor? And how about a lower kv motor? Also, on the motor page it says 3s ~ 4s lipo, so I can use a min 3 cells and max 4 cells series lipo? And what max voltage lipo can I use?

The advised motor on the Q450 frame page is the
NTM Prop Drive Series 28-26A 1200kv / 286w
http://www.hobbyking.com/hobbyking/store/__17345__NTM_Prop_Drive_Series_28_26A_1200kv_286w.html

So which one shall I buy, the 1200kv or the 1350kv ?



Can I use all of these batteries with the ESC and motor above? (my list and your advised ESC)

And the carbon propellers are a little bit too expensive for my first quad, so are these a good alternative ?

Hi mate it up to you on motors but the lower the kv the more torque so more weight it can lift if you want a fast quad then go for high kv but flight times will come down a bit max volts on that motor is 14.8v so thats a 4 cell i run mine on a 3 cell but i only get 6 mins flight but i dont need long flight times, i also use the 90c battery it just gets warm but i like them not to get hot that motor does not give spec for 10x47 blades
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=29482 look at the motor here i run them very powerful bit more in weight
my quad is not light but flys well even in gale force wind my boys is a light weight quad and he keeps saying that mine flys better because of its weight
the blades are ok but you will need to keep an eye on the under side of blades for stress facture ,as they well snap in flight use them learn to fly and save up for some carbon blades, she will fly so much nicer on the carbon ones i will try and put on some pics of what happens to plastic blades , see if you can get carbon reinforced blades they chip easy but dont flex like plastic do
i cant put pics on here they are to big, if you want to see them give me a message at holtneil@hotmail.co.uk
 
Hey there, thanks for the information. I will look into carbon blades at a later time, when I did my practice on the cheaper blades.
This is what I ordered from HK and am waiting for my order to arrive. I think this new setup is pretty good for my first Quad copter setup (below picture).
Thanks

My setup I've ordered from HK:

Hi mate looks good from here did you put spec in ecalc to see what flight time will be
the esc you got can be flashed with simonk software if you can do it its a must it will be so much nicer to fly watch this
 
ESC gives me full overload of errors :/ Also, inputting battery weight, I have to put 125grams instead of 375grams. When I put 375grams, it calculates my battery weight at 1110grams, so I put in 125grams, and then it calculates it as 375grams. Ecalc has some faulty code in the back end, so it's not 100% reliable I guess

  • The Motor Voltage is close or over to the Limit - please verify the max. allowed Motor Voltage
  • max. current over the limit of the battery. Choose a battery with higher capacity and/or C-rate.
  • max. current over the limit of the speed controller. Choose a bigger esc.
  • max. current over the limit of the motor. Please verify the limits (current, power, rpm) defined by the manufacturer!
  • the prediction of the motor case temperature is critical (>80°C/175°F). Risk of overheat, please check!
  • Your Setup is unrealistic and way out of Limits!
  • The available power is not sufficient to hover.
I don't know how to work with ecalc I guess...... Could you please help me? Thanks for any help

hi they don`t list your motor but i did it as close as possable
and it comes back ok low flight time 4.2 to 5.9 mins it said that for mine and i get 6 mins are you sure on the weight i put in 1500g and gives me hover time of 9 mins
 
Ok thank you very much, I got the same results after 3 tries, but I checked the weight under remarks: battery: weight: and it stated the weight at 1110grams, when I put the real battery weight in. (372). I got around 4 - 6 minutes flight, but then I changed the real value to 125, and the weight under remarks: battery: weight: changed to 375grams, and I got almost 16 minutes hover time. eCalc seems a little bit confusing
 
Hi mate you just need to come off site and go on again and it works right charge that battery at 1c
set the alarm for 3.8v a cell then time flight , then knock off 1 min to give you time to land
 
Sound great! Thanks for the awesome advise. As soon as I receive my order an built it, I will post video/pictures. Thanks again and goodnight

This video is invalid as it compares a 30 amp esc to a 12 amp you can not draw a valid conclusion besides the turnigy plush ESCs can be flashed to simonK getting back to the point you must do an even to even to say simonK is better it may be better but a 30 amp is always going to be better than a 12 amp in that situation
 
Thats not what video was about its show that the code simonk wrote makes the esc respond to the throttle better , and this makes the quad more stable the esc are coded to work together better , i know as i use the simonk ones and standard one the simonk are so much better
What does an esc do ? all an esc does is convert a 2 phase DC in to a 3 phase AC voltage and a 3/5v out put ,so it does not matter if its 30a or 12a as long as its over its amps to run the motor used in the test
Pro flight uk makes lots of multirotors and i think they do know what they are doing

The video is inconclusive because it needs to show a comparison between two 30 amp ESCs one simonK and one not. The simonK firmware may be better but the video primarily shows the difference between a 30 amp and a 12 amp but until everything else but the firmware are equal you can't make an apples to apples comparison it more like an apples to oranges comparison. I'm not saying the simonK firmware is bad, I've heard lots of good things about it and am going to flash my plush ESCs to it (I might shoot a vid of one flashed and one not) but in the video it can't say the only variable that's different is firmware and it's clearly not the variables introduced by havering two differently rated (amps) ESCs void any conclusion
 
I get that the video may be trying to show a larger difference because the actual difference may be to small to see but it may feel huge when you fly but still the video needs that caveat disclaimer
 
What are you going on about , it does not matter if you run a motor that needs a 12a esc and use a 30 a esc
IT will matter if you use a 12a esc on a motor that need a 30a esc .so what your saying is not valid and will only help to confuse newbies
i am not selling any thing so if i push people to use simonk flashed esc , its because they work better and are worth the extra money
SO stop digging at the video see it for what it is a simonk flashed esc works better on a motor that need a 12a esc other than a non flashed esc
and go do some thing useful and give good advice to new member
 
RIGHT think this way then a motor pulls a 12a load so you use a 12a esc as it pulls 12a
same motor 12a load so you fit a 30a esc the motor still only pulls 12a
So what is your problem
 
Hmmm. This is my thinking: Electronic switching components with a high current rating generally have a lower "on" resistance than similar lower rated components. That resistance causes a voltage drop across the unit equal to the current times the resistance. Nowhere is that likely to be more apparent than when the motor is commanded to go from standstill to full speed - the momentary surge current can be many times more than the motor's normal current draw. An ESC can take a surge greater than its rating for a short time for exactly that reason, but the lower rated ESC is likely to have a significantly higher voltage drop during the surge than the higher rated unit - which will cause a voltage sag across the motor and so sluggish acceleration. Which is pretty much what the video is showing - I'm with OU8_12 - the only valid comparison would be between two similarly rated units. As a caveat, I'm a complete newbie when it comes to electric models (just about to start my first build), but I have been an electronic design engineer for the past 35 years.
 
yes your right but its too much info for a newbie to get there head round , but pro flight have been doing quads for a long time and there techs do know what they are doing and test was just to show the simonk flashed esc are smooth and more stable
