The crappy HK eShop has sent me the TX with CH10 and the car with CH6. PS Not every eShop is professional like this one ... but find a Puchi isn't a easy task !
It look to me that there is no way to change a quartz in the car !
There is a big module that is replaceable on the TX.
It is available a TX module for the Puchi TX for cheap ... and if so where ?
I had a fast look inside the TX module ... I didn't found any replacable quartz ... is there any trick that I din't see ?
