    MR Product list of no replacement parts

    I did email Tarot. No reply so far. I emailed the guy who broke his frame and asked him what they said, his reply was their reply was just the part was not available. I started this thread because of my frustration with DYS and getting a replacement part for a loose roll connection. It's a...

    MR Product list of no replacement parts

    In the case of the Tarot X8 or X6, it's off my wish list till I see parts or buy something else. I understand my anyone would buy a frame or gimbal if replacement parts aren't available or easily made.

    Leica DG Summilux 25mm lens

    It's a f1.4. How low do you want to go? I have one, but haven't flown it. If I get some air time in the next few days, I'll put it on and give it a go to see how stable it is. Can't promise anything, but maybe the weather will break around here one of these days.

    MR Product list of no replacement parts

    MR's crash for lots of reasons. To buy something without parts is kind of dumb. This list is to help people know what Frames and Gimbal don't have available parts for replacement. Many parts can be built, but many cannot. It's beyond the scope of one person to compile a list so I thought the...

    Phobotic Centerpiece Brushless Gimbal Controller

    Short answer yes if I understand the question, Long answer: Yaw, I have follow on with a little dead band. Flying straight, gimbal stays steady looking ahead. If I yaw copter to the right or maybe fly to the right, the yaw will smoothly follow. I have the 18 or 20 degree max set up, so I...

    Phobotic Centerpiece Brushless Gimbal Controller

    Are you using 1 or 2 IMU's. I assume you did the autotune? Maybe try just the autotune 1 or 2 times and see what kind of settings you get. Are you in follow mode? If you have your radio connected for yaw, try disconnecting that first till you get it working. I remember when I first...

    Phobotic Centerpiece Brushless Gimbal Controller

    I'm being redundant here, but I've had good luck with Centerpiece (2 imu) on 2 gimbals flying gh3 & gh4 on a DYI gimbal (5208 motors) and DYS Eagle eye with large motors, 60mm or 62mm. I've talked about the horizon issue many times and am waiting for the 1331 firmware, however, mine is flying...

    Phobotic Centerpiece Brushless Gimbal Controller

    The base CP is retail $400 and the high voltage with 2 IMU's is $600. They had a black friday sale which was 10 or 15% off and additional off if you bought more. Most of us paid the $400 or $600.

    Inspired by Inspire, DJI A2/H3-3D XY4 Quad Build with a twist

    Might be worth a try. I'd probably keep the 3rd axis, just not the retracts. I like the yaw corrections when flying forward at medium to higher speeds. I've been basically flying both my 3 axis gimals with about 15-18 degrees restriction on the yaw with a little bit of dead band and quick...

    New Y6 Tri-Trooper 900mm & Pixhawk

    Rob, I checked in to the UAV-CAN GPS on Can Bus port. Probably above my capabilities right now. Will watch it for the future. Appreciate your help and suggestions. Worked on the Y6 abit today. Little setback (timewise) in trying to get my ESC's into the 30mm arms. I wasted a bit of time...

    New Y6 Tri-Trooper 900mm & Pixhawk

    That's what I thought, although I wasn't 100% sure if a brushless motor wasn't considered a servo or not.... The trooper Y6 main board has 5v on the board already, so am going to use that to pins 1 and 5 on the main power in on the Pixhawk and then use a buck converter directly off the battery...

    XAircraft Xaircraft?

    Lightandair. Welcome to the forum and a place to get many answers to your MR questions. I for one have no idea if they are still in business although as a owner of a SuperX and also have the MiniX on preorder, I'd hope they are in business. They are not the most responsive of manufactures...

    Dual Buck Converters, need design help pls.

    I will be ready later today to either pull my xAircraft SuperX or Pixhawk from one of my quads and put it on my y6 lw/ 6s batts I'm building today. My first choice is my Pixhawk, but hesitant without figuring out the power. Since I'm coming out of a buck converter and currently not using any...

    Dual Buck Converters, need design help pls.

    For the PIxhawk, IMO, it's a 2 prong reason. One is redundancy of the power, but the other is to negate spikes. Here is a warning on the Pixhawk I took from one of their tech docs. It is dangerous to power the Pixhawk only from the servo rail, especially with digital servos. Servos may...

    New Y6 Tri-Trooper 900mm & Pixhawk

    I found a redundant diagram for two 5 volt's going to the rails on the pixhawk. I'll go take a look. I've been using buck converters for everything for about 5-6 years with no issues so am comfortable with them. I'll go see if I can find it again.

    New Y6 Tri-Trooper 900mm & Pixhawk

    Have another day or two to decide, but am having 2nd thoughts on Pixhawk. Looking at power supply for 6s batteries and getting nervous. I was going to just put 5v onto the output rail, but then read this warning .... It is dangerous to power the Pixhawk only from the servo rail, especially...

    New Y6 Tri-Trooper 900mm & Pixhawk

    I was going to build my own frame with the Vulcan aluminum arms (which I am really liking) to maybe going with Quadframes y6. Then I saw the Trooper with 30mm CF arms and figured why not. Also the fact that is't 900mm and I can cut it back a bit when I find the sweet spot for props and the...

    New Y6 Tri-Trooper 900mm & Pixhawk

    Decided to try a y6 with 400kv motors and my Pixhawk. I'm taking the Pixhawk off my development quad as it's earned my respect. Replacing the Pixhawk with the new SuperX MiniX. Give that a try. I've bought a kit with 30mm CF arms which is a little out of my DIY mentality. I've been using...
