I have the P-51 pts with the evo .46 engine that comes with it. I had a fellow flyer tell me I needed to take off that engine balancer that goes on the prop back plate to get rid of some of the rotating mass to give my engine more power. If you have not seen it, it is a metal ring that presses onto the outside of the prop back plate to smooth the engine out, and it does have some weight to it. I went ahead and took it off and after a few flights I really cant tell a difference as far as the engine spinning up more. It almost seems like it might be a little worse as far as running smoothly. My question is, for those that have experience with this engine. Did I mess up by taking this balancer off and would have been better just leaving it? I didnt mark it when I took it off so hopefully I can put it back on and still be balanced? thanks for the help.
