Just a warning...the Venom Li-Power 2400mah for the Helios needs to have the polarity reversed. Also, another framerate question: will there be any negative effects from running the Tx in NORM or HSPD with the 409S or will the response simply be slower? Does the 407S support HSPD as well as NORM? Thanks in advance...I love this radio!
