So I have a situation when I was starting up my copter the other day I noticed one of the motors took a little longer to get going then the others, little longer is like a second, or less, and when they all initiated the one motor I noticed looked like it was out of synch for the small amount of...

no club, it was for a client who rented the track out.

Track day, it a very rough draft of clips from a day out at the race track. I doubted it some to some music to pass the time. Best to all

that makes sense. it falls into what I feel is happening, It just gets me on how they are marketing it and I bought into it. Now that I am having issues I feel instead of being helpful they not being the most helpful. I am looking forward for the new Gensace Tuttu batteries about to be out...

For me I wanted to start this post to hear what people think of maxamps batteries. For me it is one of buyer beware and I will explain why. In my case is a fairly straight forward situation, I purchased a maxamps 10,900 (6s)mha last June for my heavy lift Octo. Over the past year the battery...

also you are talking about a fixed wing airplane oppose to a helicopter. I like the coaxial mainly for redundancy but do not know how much more energy they take to lift copters, however with that said considering the upper motor is doing a lot of the work, by the time the thrust gets to the...

I thought this was fun to see. I am sure DJI, Amazon, and others may fear the technology.

http://www.fastcompany.com/3023139/tech-forecast/crashing-drones-less-likely-as-quadrocopters-learn-to-fly-damaged For the longest time I have been on the theory that what I would like to see if you lost an engine in flight a type of firmware that could detect it and then off set the opposing...

IrisAerial For what I have been seeing on my side of things and what I know, I have a feeling it will be fine and it will work like a charm, where I may see some issues, if its not well balanced especially on the yaw axis, when you shot pointing down I can see the IMU getting a little...

Big fan on fixed pitch props and have been waiting for someone to produce on. On the grand scale instead of relying on multiple ESC's to manage prop head speeds you now have one motor doing all the work and what I imagine servos controlling the prop pitch. Now with that control you can probably...

I will start, to date I have been pretty skeptical on the stuff I buy from RCTimer just in general, it being China, Shipping, if you have a problem getting it taking care of, cheaper cost, etc... A few months ago I purchased thier NEX gimbal and knowing all i listed above I was worried about...

That a good answer, its a design that many aircraft have to help keep the plane stable on the horizontal plain. If the aircraft slips into a right bank then the wing on the down side is more level to the lift component giving it more wing surface/lift to that side. This in turns will cause the...

On you crash I would go with the esc, It's possible you gains are to low but that all depends on the type of flip, if it was something that happened all of a sudden then I am on the esc/even a bad FC. On the gains for those motors I would say that is a high yaw gain but for the other gains that...

my only thing that I can throw in there is that the bearing set on the MT series are not as good as the set on the MN series, my experiences in the past with the 3515 motors was that I found the bearing not as solid as I would like, since I have change over my motors I have replaced the bearing...

ya that was what I would say, my magnetic deviation where i live is a -11 degrees, but when I set my GPS I am probably offset by 25 degrees. In the past and still, the way I figure it out I will take off and fly the copter straight forward, what ever the direction the it starts drifting in the...

In the past when I first got my RX100 I posted some of my opinions on the camera. Overall the camera is not the friendliest for multi rotor purposes, one being never mind for multirotor use, who would put the HDMI output on the bottom of the camera right next to the mounting screw (useless on...

mShakeShaft I am not sure if this would help but depending on your weight, take a look at this post, i am not sure if it will help but it will give you an idea of some of the characteristics I am seeing with that size motor on a general hex...

IrisAerial posted a question about losing calibration in the general comment section. His question was directed about losing calibration if a copter sits for some time. It kinda hit a cord with me and I am trying to figure out what might be going on in my situation. I have two copters both on...

So I recently decided to change out my Tiger 3515 400KV with Tiger 4012 340KV motors, I did this mainly I was not happy with the results of the bearing set I had in my 3515. Out of the 6 motors I originally purchased I had one mysteriously burn out, and 3 other motors had bearings start...

This is a collection of clips I was able to get the other day, Over all getting the footage took less then an hour. What I was finding most challenging as I do when running the rig as a one man setup was running the copter and keeping the camera angle in a decent set, at the same time. best all
