Hi guys,
I think there are some mistakes on your assumptions:
- There is no POT in the car, it is a variable inductions simbol is L. Most probably in the car there is a simple LRC fraquency range filter.
- These cars for sure have a "filter" that is far to be narrow, so I expected that you can't use two indepentent frequences, closer then 7Mhz without generate interference.
So the limit of 4 cars with a range between 27-57 look the maximum.
What can be done, is just try to go in higher frequences, till 85Mhz, so other 3 cars can run !
My approch is to have 4 Bit + 4 Smartland (infrared) this bring up to 8 independent cars. But without mods, the Bits are more performing.
