rparker396 You must be new to the hobby! It clearly states that it is analog which means that it will not work with DJI goggles and is most likely to small to accept even their smallest digital receiver. Currently the only option available is with the Crossfire receiver and almost ready to fly which means that you will have to solder a receiver in if you choose the second selection. This is a great little quad that I soldered an XT30 connector and ELRS receiver on to. I fly it with some larger batteries. It is very maneuverable and flies great outdoors.

rparker396 That depends on the laws in your country. In the US, if the drone weighs more than 250 grams, you need to license it!

rparker396 No idea, threw these in the trash long ago!

rparker396 It tells right on the box in the video. Watch the video on the sales page!

rparker396 I have no idea! I would research it and get the measurements of the bearings you have and see if they are the same!

rparker396 I am a drone pilot and attempted to delve into planes for a short time! I managed to destroy this and a wing in less than twenty minutes, so in answer to you question a train battery would have fit mine when I was done with it!

rparker396 Yes, but it sounds much cooler to say I have a crossfire rather than a frysky!

rparker396 I have never had it apart, but if I were to guess, the metal gearbox wheels and tracks are all upgrades on other Henglong tanks. I have a panzer IV and a sturmgeshutz and both are upgrade models with metal gear boxes!
