On the flip side to this, and I’ve seen this before too,….if the engine SEEMS to wake up in conventional, ie; sounds start immediately, BUT you have control of the engine via the remote, this suggests an issue with the IR system of the engine. Misaligned drawbar, broken, pinched, or shorted wires, etc, etc,….you may want to have somebody look at that engine for you before you have the dreaded runaway…..
