Currently I am using an XPS JR module in a RadioMaster Tx16s with 16+ nano receivers. Before this I was using the Futaba module in my 9c radio. I have used the RM setup for the last three seasons. Last season I crashed my funjet due to loose of control. Unable to determine the cause I replaced the nano Rx and gyro and moved on. I had no issues till about two weeks ago, I tried to fly my funjet on a hot ~85-degree day and during my preflight I noticed the servos movement was choppy and lagged the stick movement. I had several flights before this on other models. I assumed it was either the nano receiver or possibly the gyro in the plane. I could not reproduce the issue on the bench, so again I replaced both the rx and gyro (installed another nano rx) and had no issues for several flights since.
This past weekend I was out (again a hot 85 degree day) and tried to fly 71” Slick about mid day after 3 previous flights. I experienced the same laggy choppy servo movements. This time I immediately switched to the funjet and had the same issue making me think its an issue with the XPS module. I wish I had then immediately switched to my small heli with a Spektrum rx (to rule out the radio) but this didn’t occur to me. I later (same day) flew the heli for several flights and had no issue. Both sessions were hot sunny days and I sometimes leave the radio on while changing packs. Till I resolve this issue I don’t feel confident in using my XPS equipment. Do these symptoms sound familiar? Could this be a heat issue or just a failing module? I see the JR modules are out of stock. What are my options? Thanks for any assistance.
