An excellent usually bullet proof receiver. To verify problem is with Ch3 of RX, try swapping aileron & throttle servo leads, and see if same problem transfers to ailerons and throttle remains AOK. This whilst range checking at various throttle settings on the ground. it could be the servo, leads or intermittant fuel supply - little gassers are notorious for fluctuating fuel feed problems as they age or have been sitting unused for a period.
Refer also "Radio Systems, Accessories, Alterations and FAQ" sub section
"Receiver - FAQ, guides and aids to best reception.." on my web page.
If above does not assist, send RX in for a full service check.
