WILL THE 502F MODULE AND THE 302F Rx WORK WITH THE OLDER KO PROPO MARS - R ?
ALSO WHAT THE DIFFERENCE BETWEEN THE 501F MODULE AND THE 502F?
I'd say no because the helios was designed with updated software which is alot faster than the mars so their (helios) module would be faster just like their recievers (302f)
