what chip?
 

who knows what RX/TX chip these have in them

Probably RX-2 and TX-2. They all use the same chips for R/C cars nowadays.

yeh can some one check casue im working on propo emulation and i need to look up data sheetd for the chips

I was telling you the answer dude.

have u checked man?... cause i dont wanna built a whol system to find out the chips all wrong

Has to be a TX2-RX2 or copy of it
 

I'm sure it's a TX2-RX2 set, or at least a clone of it, Zipzap, Z-Car and some Bit controllers will work on it, so I'd go with that.(all these have TX2-RX2 of some kind)

told you so
