@AgoraSam - to be fair, that troubleshooting guide sort of treats us like we don't know what we are doing. Anyone that has built this tank is surely smart enough to check for clearance issues with the vertical barrel movement, or too tight of screws preventing the turret from rotating.
The camera not working (that was THE selling point for me) and the electrical, 'gremlins' look more like circuit board problems/failures, and some REALLY sloppy programming.
I suspect Agora got a bit over their head with importing something that obviously wasn't prototyped correctly, and I do sincerely feel sorry for you guys for being in this kind of position. But for working folks, this was a lot of money, and I do not think it is unreasonable to have expected something a bit more better flushed out.
Also, where in the hell is my Ferrari 312? 🙂
