This is why I tell people to get a minimum 8 channel compuyter radio. Not that it can't be done with 7 or even 4, but the minor difference in price (like $59 between 7cap and 9cap, and the 9cap comes with a R149DP receiver vs R138 with the 7cap) is meaningless compared to the features. Use one feature 1 time like ailevators and the transmitter paid for itself.
