HexaCopter take-off problems

Hey all, I'm having some real problems getting my new guy to take off.  This is everything from the jDrones kit (except in the Xaircraft hexa frame), 850Kv motors, 20 Amp ESC's, hexa PDB, 10x45…Continue

New Hexacopter issues

Hey all,I just put the new APM 2.5 and a new PDB on my Hexa that was going crazy in this post:http://diydrones.com/forum/topics/hexacopter-take-off-problems...and everything worked great!  After initial setup, I was able to hover and move around indoors without much effort.However, after a few flights my horizon started to get kind of wacky and I'd have to recalibrate after each flight.  Then, all of a…See More

"I'm back! So, after adding foam to dampen the vibrations to the APM, most of my issues were resolved, and it flew pretty well... After not using it for like a month, it now wants to flip over (to the right) when I give it any throttle.…"

"Hey Dusty, Looks like I fell off the face of the planet for about a month... Anyway, I'm using the DX7se controller, and I have the controls set non-linearly (It makes the flying on my MikroKopter incredibly easy). Also, are you flying in…"

"Blaine, we are running the same machine; APM1 on XAircraft Hexa with Jdrones Kit!!! And I experience almost the same problems. It never lifts staight-up. Difficult to control. Motor vibration is very bad. Even I balance the prop, upgrade the prop…"

"Yeah, Rate_P is too high in the video. If you tune it down you need to increase Stab_P to be able to control it."

"If I change the P to 0.07 it stops fidgeting enough, but it's definitely still not stable.  Also, when I give it pitch/roll it seems like it is barely responding."

"Here's the latest and greatest video: RATE_P is set to 0.144 I and D settings are 0. STB_P is 4.5 and STP_D is 0.005  "

Jan Schermer replied to Blaine Hoyt's discussion HexaCopter take-off problems
"No problem. It will always vibrate slightly at different RPMs, that's what multicopters do. I personally never had to balance props or motors, not even when the prop hit something solid and snapped some material at the end. But in the end it…"

"Thanks all for the help!  Turns out I was just pussyfooting around the controls and throttle.  As per Jan, I changed up my RATE_P and am seeing better results.  It's still pretty dang tough to fly, so it definitely needs a lot of…"

"Just saw this now - take a look at my other post. You need to tune it a little, and it might never be as "perfect" (every controller is different, some regard for example Multiwii as superstable, for me it's unflyable, YMMV :-)).…"

Jan Schermer replied to Blaine Hoyt's discussion HexaCopter take-off problems
"I don't really see a problem here - it's better to get it up faster than to try keeping it in place on the ground - hopping on the ground can cause the copter to overcompensate and even flip. I think you should do a hand test - hold it…"

"did you really make sure it was level when you hit the level button doing setup. this is REALLY important. it affects how it flys."

"It's hard to tell in the videos- which way is your APM facing? Do you have the servo connectors pointing exactly toward the back of the hexa?"

OK, I'm game.  What are you having trouble with?

There were actually a few things that I had to modify.  I am not sure where you are starting from.  I had a jDrones hexacopter kit (full electronics).  Crashed that and it was toast from a mechanical standpoint.  Cheap piece of crap if you ask me.  I have 880KV motors and 10X4.7 blades.  Get the better blades, much tougher and better balanced out of the box.  The electronics fiberglass plates didn't line up well and as you noticed the power distribution board had to be modified with four holes to attach that.

Since that time I crashed the copter twice and had to rebuild.  I lost a prop and fell from 50 feet on its head, broke two arms and fractured some carbon fiber.  I decided to buy an additional xAirplane kit just for spare parts.  That worked out pretty well for me as I am still learning to fly.

Also, I really like the idea of the open source development of the Arduino controll mechanism and the expandability of such, but I have had some pretty hairy experiences with getting it to work in a manner that I am not in fear every time it goes up.  I decided to get a Naza controller and will get that in the next couple days.  The arducopter thing is just a little to developmental at this stage for me.  they will get it sorted out eventually (I think) and I will go back to it.  I may build a smaller quad with the Arducopter controls in the time being, haven't decided. 

My goal is to be able to take it out and do some video, possibly hook up FPV once I am comfortable that this new controller will work well.  I practice with a Blade MQX and I am getting pretty comfortable with it, but I still have massive trepidation when I send the big bird up.  It truely could kill somebody.....not good.  So, it needs a trustworthy control for me.

Did you get your takeoff problem fixed?
