The thing is i've never flown anything what soever. Well, a plastic fixed pitch 30dollar toy, what you can't call a copter, because ist uncontrollably cheap. So chances are great that when the first time I let the copter take-off in the air that it wil fal down ''like a apple from the tree''. So when i was looking around on the dutch forum my eye spot the word ''Multirotor''. Me; Huhhh??... thats interesting; flying with no hands. I like that even more than the apple thought .
So i began searching on what i needed (because i wanted to build my own multicopter of course) at parts.
I already had find Hobbyking, because of my already orderd HK-450 pro.
I looked at what they had and made my coiche to take carbon fiber 300x100mm sheet As beginning point and make a frame out of it.
Here are the parts i orderd already;
Again, this is my first so i have orderd what i thought was best (not knowing anything about motors and esc's combinations).
So yes, probable need some other and better parts later, but for now i'am trying to make a tricopter out of this parts.
And special thanks to Dave for providing CC
Wel, now for me the hard part is design a frame. Only program i have design't with is Paint....haha.
So that had to change, i just only had to find out what or witch program i needed and illegaly download it somewhere.....sssssst. The hard part for me is educating myself with it so I could actually draw some 3d. oh boy... was that gonna get a mes, but i had to, because I already ordered half of the parst with my dom as before even knowing what i was making realy. So i made up my mind and choose a Tri-copter to build, mainly because what i thought; les motor, les esc = les buck. Wel, also found a 3d moddeling program, Google skechup had to be it. I thought to my self; what am i getting myself into, not knowing anything about any copter and 3d moddeling program. Wel actualy after two days of fighting with skechup it wasn't that bad at al of lurning to work the basics with my agrarian intellect .
So that said, here's my design;
I thought i keep it as simple as possible and tryed to minimize material weight.
The tail rotor, i thought about for 3 days how i could possibly get it as slick as i can.
Don't know if it wil work, not seen anybody do it like this. And stil waiting for parts from HK.
As you can see, the servo wil push itself of the fixed servo arm that i'am gluing to the tailboom. And if it does witch i think, it wil also take and turn the motor with it.
I've seen other people mount the servo on the tailboom, but that creats more surface area and so, i thought less efficient, because it wil then push itself down.
At least that's my theorie .
Some parts that have arived.
So affter designing i wonderd if you could Print out a 3d model in 2d on a peace of paper.
After a quick google i found out that it was indeed possible, but why would you mention it here you think?
Mann... is google skechup a peace of work. After 30 times mis printing the model, because skechup always wants to print the rounding area around the model so it spreads out the model over 6 or wathever nr. of papers. But finaly i figured it out and viola......scale 1:1 exact. ( I have coppies, so if anybodie wants to build it Pm me).
So now the part where I'am good at doing stuf with my hands .
I thought, there is know way you can draw the the model on a hard piece of Carbon-Fiber. So i taped the paper to the CF sheet and carved it in with a stanly knive.
An canopy would easely fit, because the frame is reasonable thin. The canopy is from the cheap 30dollar heli (450 size) i mentioned earlier.
But i think that it needs a 500 or 550 size canopy, dunno yet. already orderd aan 600size for 4.3dollar on HK to see how that would fit.
That's it for now, because i'am waiting on HK for the carbon fiber square tubes. Hope you like it, grtz johan
