Howzit everyone
Newbie here looking to delve into the realm of MRC's! My aspirations include aerial photography and FPV, but as I am a newbie I still have alot to learn and have yet to fly a MRC, but I will soon hope to solve that problem!
So first things first, for some while now I have been researching quite a bit into multi-rotors focusing mainly on frame designs. Only recently have I been scratching the surface on the electronic side of things. Reason being I am more mechanically oriented and that is why I started there. And although I am still not sure what electronics I am to use I could not resist and built a frame anyway! I do have a friend who sells hobby electronics and I borrowed some basic things from him that I modelled and included while I was designing, which helped a bit.
So here is what I came up with so far:
Concept
Laser cut
Assembly
As you can probably tell this is a small quadcopter
Only 350mm from motor shaft to motor shaft. And further more may bear ressemblance to the 330-X in some ways(which seems a popular choice for beginners). My dreams are big but I knew I had to start small, no point building something large with no idea of all the problems I am yet to face. So priority is to get something in the air, that doesnt cost an arm and a leg, crash it a couple hundred times and learn. This was some the advice I gathered browsing these forums, and I am sure it will pay off Further specs on the frame in case you were wondering, as mentioned 350mm, weight +/-300grams. Laser cut from 1.5mm Aluminium 1200H4 sheet, then bent and fastened together using stainless steel M3 Bolts. The 1200H4 I fell is not strong enough to last and I can already picture it crumlping into a small mess if it crashes hard (I made a few spare arms already )... But im sure I will need to make some changes to it down the line it which case I will update it and then make the frame say from 6061-T6 alloy.
Electronics: I'm no sparky...
As mentioned earlier my friend sells some hobby electronics and has also started bringing in the ardupilot flight control. So this is what I can get locally, and by locally I mean just down the road, and also at a very good price
Aeolian Motor C2822 KV1200
Rotational Speed: 1200 (kv) RPM/V
Continuous Current: 15A
Max. Current: 25A
Input Voltage: 6 - 11.1V
Max. Efficiency: 98%
No Load Current: 0.5A
Internal Resistance: 382m(Omega)
Power: 135W
Motor Weight (Motor only): 35g
Aeolian 25A ESC
Input voltage: 5.5V-16.8V (support 2-4S lithium batteries)
Continue current: 25A
Burst current: 30A (within 10 seconds)
BEC output: 2A/5V (linear)
Suitable for aircraft Brushless motor
Size: 50x28x12mm
Weight: 31g
2200mah 11.1v Burst 35C Lipo battery
Slow Flyer Prop 8x3.8
I also discovered xcopterCalc on these forums and when I punch in the numbers I get a very poor flight time I have a few other battery choices which do help the flight time a little bit but the throttle percentage required to hover increases close to and past 80%. I think my biggest problem are the motors, esc's (too large and heavy? 330-x uses 10A esc's) and props. I designed my frame around 8inch props same as the 330-x, however I might be able to squeeze in some 9 inch props. I was wondering if anyone could point me in the right direction regarding choosing the correct electronics for this small quadcopter as well as any other advice and input would be greatly appreciated
Hope to be flying soon!
