Hi all. I very recently got the Piper Arrow III so I could practice flying IFR in a complex aircraft. I started out by doing a familiarization flight so I could get a feel for everything before going IMC. However after I finished cycling the prop and putting it full forward, I noticed a rhythmic dip in RPM. Changes in manifold pressure didnt do anything, nor did checking the mags again, so maybe it was a prop governor issue. Maintenance hangar didnt reveal anything. I doubt this was a bug due to the high fidelity of the model, so I would be open to suggestions as to what could've caused this and how I can prevent it from happening again.
