Nope, the Seeker II receiver has 8 channels, the Seeker 6 receiver has 6 channels. You decide which receiver when you order. The Seeker II costs a bit more than the S-6.
Nice to catch a nit-picker with his pants down. (G)
At the time I ordered my Tracker III w/Seeker II Rx (called seeker 8 on the invoice), it cost $200 + S&H. The T III w/Seeker 6 was $180. Either version came with a dual charger, switch harness, set button and
900 mAH flight batttery.Why bother with one servo? Polk's figured the buyer would need at least one servo in order to check out the system! The Seeker receivers will run virtually any servo on the market today and Polk's figured the type of servo was a buyer elective depending on the application. Additional Polk's standard servos are available for $10 each.
