I don't have an Iris but I do have a 3dR RTF quad and one of the new Pixhawk X8's. I've also been responsible for the purchase of two other X8's that are currently being used for filming purposes. All of this and the following activity has occurred since ~January of this year, 2014.
The 3dR quad is quite similar to the Iris, but uses APM 2.6 as the flight controller with the aircraft having a somewhat different appearance using a different type of radial arm. The 3dR quad uses for all intents and purposes the same Mission Planner and computer software installation as the Pixhawk and Iris. The quad and the x8 can be operated without being operated jointly with Mission Planner and a computer. This is something my colleagues and I do regularly, only connecting to a computer/Mission Planner when we need something changed, to review flight logs, or to operate autonomously using a flight plan. We have absolutely no problems with flight operations in any mode but we do take the time to read the manuals and instructions, which are quite informative and extensive in their content. The 3dR documentation is published in a web based format at APM Copter and requires some effort by the user to review.
I have on several occasions had need to contact 3d Robotics for parts and/or information with each contact being handled well. The first time I made contact the individual on the 3d Robotics end spent pretty close to an hour on the phone answering my questions about the product. Delivery of the first quad order took a couple weeks but it arrived well packaged, protected, and 100% functionally intact. The next pair of X8's arrived at their destinations after around 2.5 weeks, again well packaged and functional, with the last X8 (third X8) arriving at my house after only a week from the order date. With every order some extra parts were ordered at the same time as the aircraft order, and in every case the extra parts were shipped within 2 days of the order and delivered well before the aircraft.
So let's just say I've had quite a bit of experience with 3d Robotics, their products, their ordering process, their personnel, and their customer service. Nothing in the 281tx postings is consistent with my experience. Some of the issues described in those posts indicate the user failed to read and/or follow published documentation, and an acute lack of system understanding is quite evident.
I am not aware that customer service at 3d Robotics had taken a turn for the worse since I began doing business with them. My experiences have been quite good. The DIY Drones website is rife with information useful to the consumer. If I had any area that I thought needed improvement it would be for the technical side using direct communications (phone or e-mail) with company staff. Some improvement in that area would be helpful since it could better direct the user to appropriate reference material at the DIY Drones or APM Copter websites. The company should not have to hold a persons hand and walk them through every step of programming and operations. It's presumed that someone purchasing a higher level multirotor will have some level of computer skills or operational experience that enables them to understand the product they intend to purchase. It is also presumable the purchaser will have or intends to obtain computer equipment that meets the minimum system requirements, which are published in 3d Robotics documentation.
So my personal experiences indicate something isn't right in all of this and I'd sure like to know where the missing pieces are that clearly define where the problems are.
