I got my son one for his birthday last week. I thought I had difficulty binding it to a DX5e in that to arm it, you hold the trainer switch in on the transmitter. The quad is not documented for this transmitter. If the throttle is over zero and you pull back the trainer switch, the props don't spin. Bring the throttle to zero and you can take off. It's a trainer for him. Let go of the switch and it falls out of the sky. That's the only failsafe I can see with this rudimentary transmitter.
After about 2 minutes the throttle is in the upper range and control gets sluggish. I land it then. Heard that flight duration is realistically 2.5 min. Since I have no telemetry it's a guess.
I'll be watching to see what develops here.
It has two modes. The attitude mode is docile, in yaw especially. I can't fly rate yet so I can only say the release of the trainer switch is a good bail mode. I did read that it comes with three modes. The DX5e isn't accessing one of them. Outdoors in wind today bounced it around and made it kind of oscillate. Not a windy day machine. But I never heard they were. Camera worked well indoors. Did not try outside.
