A part of the review has been auto-translated.
I have started a detailed review on rcgroups.com entitled "MD-Tech Pterosaur 1400 EPO 4 Channel Trainer". Google that with rcgroups and you should find it. Unfortunately I have not been able to fly it because of COVID restrictions, but have reviewed it based on design, likely suitability as a trainer, quality of the components, ease of build etc. On those measures it stacks up pretty well. And, strangely, it came out at 730g ready to fly with a 1480mAh 3S battery, quite a bit lighter than Banggood is saying. I think even with a 2200mAh 3S it wouldn't get to the weight they state. So I think it will be a nice, floaty slow flyer. I have the PNP version, but there is quite a bit of assembly required even for that version. Nothing too difficult though.
Very good plane. PNP version is missing the foam glue. Everything else is there.
