Default Brand new Mulit-Rotor Helicopter Forum

Our fearless Administrator has set up a new forum, celebrating Mulit-Rotor Helicopters. Now I don't know much about them, other than they usually have four motors and four propellers and look really cool. I have watched videos of them and wished I had one, but I never took the leap.

Now that we have this forum devoted to them, perhaps we all can be enlightened by the knowledge you quad guys have.

So fire up those quad rotor craft and lets see em fly.

I just know there are those folks out there who are just wanting to tell what they know about quads. Don't be afraid to start a thread, because you probably know more than most if you have a quad.

Default ok i will start thread on hk quadcopter v2.0

well ill be first then, on starting thread as requested

i find and im just starting out, at first there scary, but once youve done it, its great, there a bit tricky, and not as hard to fly as you think

will put up this vid, bare in mind its my, 1st maiden flight and never flown these before, heres the link

Thanks Skyhawk for getting the Quad form rolling.

Was that a really big sigh after you got it back on the ground in one piece?

I have seen video of quads going under small bridges, under guard rails on those bridges, under tree limbs and around all sorts of stuff. They look really fun after you get the flying part down.

I have an mQX that is driving me crazy...it worked perfectly and then started flipping from the right to left when trying to take off. I don't get it.

They are cheaper than I thought. There is far less damage in a spectacular crash than any model plane. I mean, I have had several bad upside down crashes and only broken a prop each time.

You learn real fast

They are (in my opinion) much easier and cheaper to fly than helicopters. (Yes I have been there)

There are several types of flight controllers, eg Arduino
I use a simpler one. The KK2.1

There are Flight Control boards that have Altitude hold and return to home and are expensive. (GPS Baro etc)
Or you can have a cheaper fun fly board like my KK2.1 with self levelling.
I am enjoying a break from planes and gliders and learning something new.

Default The old man and his Quadra copter project.

I am new at this and it is hard for these old gray cells (85) to comprehend all that's going on. Electronics had changed so much since I retired about 25 years ago that I have a hard time understanding all the new jargon.

The attachment shows my creation, is not quite flying yet.

Nice to see the new section.
I've been having fun, if you can call it that, with a proto x, a 180 qx, and a HK450.
The first 2 are a quick out of the box fix. The HK450 is more of a hobbiest quad as it uses a kk2 board and standard esc's and motors.
Turns out I'm terrible at flying them but I keep trying.
For some reason I keep thinking I should be able to fly them easily, being able to fly fixed wing and all. But intellectually I realize they are apples and oranges and there will be a learning curve.
I must say that whereas I was up and flying fixed wings on my first day trying, the multi rotors are kicking my but.

If I do this while pushing the right stick into the three o'clock position then it goes into the self-leveling mode, which I think is normal.
Is this something that has an easy fix or should I not worry about it?

Hey Rolf

Could be that your throttle is reversed. My KK boards arm with the throttle down.

Just a side note.......If that Exceed 2.4ghz is the older PC formatted TX, you are going to have nothing but headaches with dialing in any rate aspect or trim leveling.....and YES, you should worry.....a lot...!

The 6 channel RX it comes with has a history of failures, particularly when incorporating it with any additional operating systems required to provide self leveling, throttle management and axis ratio control........it will not perform well (or at all) under the load of more than one ESC.......

Best advice one could give you.....invest in a newer, self contained, programmable 2.4ghz TX/RX.........move up into the light......It's getting darker by the minute in the dungeons of prehistoric electronics......nearly all OS's being manufactured today are NOT compatible with the older TX's and RX's....(a few exceptions would be the Airtronics (Futaba 72mhz) systems that are still available)....but that's it!

I realize you have "a few years" on us and are just getting back into the RC world......but todays shows are not yesturdays B/W re-runs........and the place and time your in today has little room for additional complication and frustration......do yourself a huge favor.......invest in today (it's even cheaper than you think or was 5 years ago) and the learning curve (I'm 60) is not as dramatic as one would have us old timers believe.....

The motors speed up when I push the throttle forward. Should I still reversed the throttle? And how would I do that?

That has me stumped. I have used that radio for robotics and the programing is done via a connected computer. If it was reversed it should not spool up the motors as you say.
