Mike,

You may be able to roll the plane without ailerons:

You will only need three standard analog servos that center properly and in a consistent manner.
All brand name and some non-brand are good; just check some reviews.
Verify that the receiver (three or more channels) and transmitter are compatible in frequency and shift (negative / positive).
