This is a "Prototype" octacopter for my actual plan of octa.
Motors: 5010 360kv
props: 16" CF
APM : 2.6 with Arducopter 3.1.3 Firmware.
Frame is 1250mm Carbon fiber and it can not fit props more than 15" as a plain octo. and for my "Actual Plan" I don't want to make an X8, because as I read many thread, X8 has 30% less efficiency than a plain octa. My idea is to make an octa with 20" props , but for this size of props, required frame size could be too big to carry around. So, this prototype is like a "proof of concept".
I had 360kv motors for a long time, so i tried a new Prop layout to make 17" props fit on 1250mm frame and they are about 1 inch overlapping each other.
I inverted all CCW motors down and accordingly mounted props.
and left all CW motors on top and mounted props as usual.
I Just did initial setup and Without any PID tuning of APM2.6, it flies very well on default PIDs.
Question is : Is this setup/layout is less efficient or more efficient ?
Is it reliable ?
My actual plan is to build a copter that equals SteadiDrone QU4D X in performance.
for that I have following items in hand.
1- KDE Direct XF4014-380kv Motors
2- 18" and 20" High efficiency CF props.
3- Hobbywing Platinum 40A ESCs
4- T-Motors 40A ESCs T40A
5-I have many frames that could be used , or DIYing a frame isnt a matter.
For my Dream copter, that could be and octa or X8 or a simple quadcopter, I think this list is good to go.
As Gary McCray wrote in "Advanced MultiCopter Design" that :
"It is feasible to produce a QuadCopter that will approach the performance of the $15,000.00 Steadidrone at a fraction of the cost."
Suggestions are appriciated.
