Bearing condition and keeping motors clean are big items. Many fail to recognize that when departing and landing in a dusty environment all that kicked up dust gets into the motors, which causes wear and binding. Really hard on gimbal motors since they are right next to the ground. Most...

Cost, additional weight, reliability. It is done but not often.

Just another basic frame with what are likely under designed landing gear. Why not obtain a Tarot or Carboncore and have good quality going in the door?

Dead on the money. Flight responses with an X-8 are much better as described above. The DJI method is not as stable nor does it provide the best control response. Extreme fine tuning of PID's will help minimize the yaw issue but a small amount of yaw will likely remain. The larger in mass...

It appears someone has a fertile imagination, is pretty good with artist concept imagery and commercial packaging, but really short on the concepts of general aerodynamics and physics.

I hope they are using the T-Motor Flame 80's. those have been independently tested and hold up at 100A;). I don't get too bothered about the prop size differential because the disturbed air cone from the upper props narrows quickly. However I agree having a larger prop on the bottom would be...

That's a little over 339,000 Rand at yesterday's exchange rates.... I really like their stuff but perhaps they like them more.

Unobtanium $25k before payload? Ouch!! That could make for a hard decision. Down payment on a house, or a new MR before adding payload equipment.

I'll wait for the perpetual power supply.

I plan on looking into their pricing structure for this one. I like the versatility and payload options. The arrangement would pretty well suit most of what I do or plan to do if the FC is the right one. Pretty sure it is.

Had some work instructions a long time ago that said to place a quantity of the stuff in the top of a spark plug cap before installing the cap on the plug. Whoever had written that instruction had clearly never run a spark ignition engine before...

If that grease is a "dielectric grease" stop using it on connections. It's designed to inhibit electrical contact, not assist. Learned that the hard way with some military stuff. Took a while to figure out why we were having a lot if current issues.

Earlier 3DR APM baro units were not insulated but they referenced this in their Wiki and provided an instruction to add a small piece of foam over it.

Interesting thought.

I understand, however, those making products for commercial sale from open sourced software/hardware may have a tendency to take short cuts in materials, workmanship, and programming of their products to reduce costs and maximize profits. Not to start an argument but IF Walkera was using 3DR...

Dazzab, I believe Walkera used APM type FC's, but not specifically 3DR. More like clones of 3DR products. If the OP can get his aircraft a solution to his problems might be to replace the flight control system with genuine 3DR products. Not an ideal solution from a financial perspective but...

I share some commonality with your set up in using extensions and additional XT connectors on a hex. It's a condition I intend to clean up one of these days through re-wiring and elimination of some of the connectors. Every one of them I can eliminate will reduce resistance losses.

Steadidrone has held some pretty high standards in their product line. This new offering has a lot of potential.

Our government has had the ability to jam MR FC systems, or any other device using a radio frequency, for a very long time. Taking control of them is now a big focus.

I have GPS installations in use that run from being flat mounted on a frame plate component (APM 2.6) to on masts varying in length from 4" (Pixhawk) to 7" with a JIYI. Had DJI's with long masts as well. The one that seems to function the worst is the surface mounted APM, having very slow...
