Making headway with first Quadcopter.

Well, here's the first photo of my quadcopter.

Weighing in at 590g as it sits, with a span of 25".  I plan on adding some litening holes in the body plates and landing gear to reduce the weight a little.

Cutting the bolts will lose a few grams, but this is just a dry fit, so nothing's done as of yet with any permenance.

I plan on powering it with seperate batteries for eletronics and flight, the motors will be 4 Turnigy  TR35-48-B, 900Kv motors with Master airscrew 11*7 , 3 blade props. powered by a Zippy flightmax 5000mAh 5S1P 25C battery.

This will have telemetry, video, sonar, gps, magneto, APM with all the bells and whistles. Hopefully I willl be able to get some decent flight time out of it.

Would it be better to go with 2 blade props, or what I have spec'd? I'm not looking for acrobatics, just long stable flight.

I will update with pics of progress as things start to evolve more.

  • Chris, I also tried similar approach, around one and half years back but found it not the succesful. The most drawback of such approach is that even little bit of hard landing would result in stronger punch to the Quad.

    I've rebuilt my copter 5 times now. Only a few original parts on it. Not to say the original kit is bad. It's great. I've just been flying a lot of my development code which can be bug ridden.

    If I go back to arms like that I may do a closed loop for strength with some sort of shock absorber in the linkage. Right now I have two chunks of 3/4 inch foam core for legs until I do something better. Really ugly but it protects the battery in a crash.

     

  • @ jasonshort.. yes they are.. Great!  lol.  I think these may last a bit, they're 1/2" x 3/16"     6160 aircraft grade. they're only 4" long, but the pic makes them look longer for some reason. If they don't cut it, I'll re-think them along with any/all components. The litening holes should weaken them some too.. lmao. I may go plastic along the way, this is the first run at it all.. I am also thinking plastic for the bottom belly pan too for weight.

    Thanks for the info tho' input is always appreciated with any new project.

    Is that gear aluminum? I made almost the exact style of legs and they worked for two days before getting work hardened and cracked.
