RE: SPA Aircraft Engines
I think just the opposite. Maybe Terry in LP will let us know. I just switched everything over from Intruder # 1 to # 3, except the servo's. I am sure they are fine, but I like to install new on any new plane. Engine is good, very broke in, SF61. I will test fly the receiver in the trainer/test plane first. I am using the R7000 rx with the X9303 TX. I finally found how to slave GR to E. May need some help in sub-trim, as when I use the trim button, only one E servo in the back moves. It was easy with the 921 RX.
