Its not poorly made at all, it just doesnt like being crashed or landed on without the shell on- I popped mine open several times without the shell on but it works fine still; optional hold-down should be compulsory really ( mounts the switch to the esc so that it wont get ripped away in the event of a crash ).
I cant believe you're still faffing about with the reverse issue though- its been months since you first had the issue, and each time you start a new thread about it you get given the same answers/ solutions ( you could just mail your whole setup to me & I'll fix it for you in 10 minutes or less, or your money back )
