Recently my MR01 have problem wirh radio range, after drive about 5ft distance the mini-z gone crazy driving on its own, twitching, accelerate by its own, non-responsive and have its mind to wonder around the ground. Its the same effect when you remove the crystal on the receiver PCB. If you look around the internet most people would sent it for warranty or just by new ones. But now worry no more.!!
Yesterday i discovered KYOSHO sweet spot for reviving dead range for MR01 board after run some point to point touching on the soldered location point on PCB board using a long copper antenna to disperse random sign of RX signal. If you have a dead radio range less that 5 feet then this is the fix for you. By default the antenna soldered on circuit lane labelled "L3" just after the resistor placement. Look at the PCB board you'll notice beside lane "L3" there's "L2" . Note that "L2" does have empty cut off empty space usually reseverve for future resistor placement just the opossite side of "L3" resistor. If you have range problem remove your antenna wire from L3 and solder on to the 2nd solder point of "L2". Look at the diagram/schematics below.
(lane "L3") o----------o [resistor] o-------------o[antenna wire]
(lane "L2")(1) o-------o (2) [empty resistor spacing] (3) o--------
**solder your antenna wire at (2)
After that your MR01 PCB board will back alive with much better and far radio range, completely stable!

10 years later you help me to solve the problem!!! hahaha i have resurrect my old miniz thank you!
ps:probably you dnt remember that you have a blog :'D
