Hello, I designed and built a frame I want to share. I hope this is the right place.Designed for power and lifting. Also easy to repair.Let me know what you thinkI am open to working more so please…Continue
"Here is a block drawing I made I think this would be good as a stick so that it will fit in thin places, also the way the power is routed, there can be a large amount of capacitors along the side wihch will be away from the heat source and not…"
"dear Chrisa, thanks for the offer. We are working on the frame currently, so OK. But would be good to have your idea and comments first. So the craft should be fitting in a 2.5 by 4 meter area. Next, we are interested to know if you have also other…"
"Because you don't need to use any differential feedback for small craft with good response.
If it was a larger craft the inertia of moving would cause it to overshoot which is why a negative D is added, to reduce the speed as it approaches…"
"So are you relying on the supplied tools only, or do you know anything about PID?
I think you should understand PID first, try Wikipedia.
In general, you would want to have D low, almost 0, I also low, but sometimes it helps, and P is the one that…"
"It seems like "the payloader" (just an electromagnet from a solenoid) is a waste of weight because of all the wires and magnets, and contraptions that need to be attached, and it only can carry 1kg, which is pathetic as far as…"
"I used eflite motors and they all have lasted through 5 crashes. The bearings look replaceable.
They also list honest numbers for ratings on the website so you can match the esc to the motor, or just go with 20A or 30A and 3S. The brushless gimbal…"
"Thanks for all the comments I will update, maybe help others or post a round a little bit, or just shup for a while.
The Eflite motors are really good I have not had a problem yet. Even after that crazy crash.
Because the arms are so thin, the…"
a the good thing is its all the same part, you can add more for more strength or take off for less weight.
2.yea that explains a lot3.time to show you this4.was directly attached to the motors so…"
"That's a contradiction. You're flying it here, with the "no spar" at the top of the frame.
And it's not just arm length that will show up this fundamental frame weakness - weight will too. Like the contraption you have…"
dear Chrisa, thanks for the offer. We are working on the frame currently, so OK. But would be good to have your idea and comments first. So the craft should be fitting in a 2.5 by 4 meter area. Next, we are interested to know if you have also other skills to contribute. Currently the issues we are working on:
Stabilization soft and hard ware: how to improve on this( we will have the 3Drobotics stuff) but have not much understanding of it yet:
The issue is redundancy: so we think to have 3 separate systems so that the ultimate control will take the best choice (2 that are same). we are not having much experience. May be you can shed some light on this, how that is done in the normal quad/hexacopters Hope to hear, Best Winfried
