After correcting the prop tracking and re-torqueing the prop bolts on Scout's woodenprop, I performed a dynamic balance using the DynaVibe instrument and procedure.Scout's prop balancing was written up in the current issue of Contact!Magazine, but that is irrelevant to my post. I agree with the "just do yourbest and go fly" when it comes to these airplanes, but being an engineer andhaving the instrument available to me, I just had to do it anyway.In order to get the engine/prop in better dynamic balance, I ended up fabricatinga fairly considerable steel plate that is mounted under two of the prop bolts.My engine is an A75 with the flanged prop hub, not the tapered shaft. Icalled it good enough when I got the dynamic acceleration down to about 0.1 ips.With that said, I will also mention that I have since moved the airplane fromhot and humid south Texas to milder and drier southern Oregon, so I have noexpectation of the propeller tracking or bolt torque still being good, and Ialso have no expectation that the dynamic balance will be the same as it waswhen I made the adjustments. However, I do expect the out-of-balance to be minoronce I deal with the prop tracking and bolt torques.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 15 Aug 2013 10:34:17 -0600Subject: Re: Pietenpol-List: step forward

Nice, Ken! I'm assuming you have weight in the tail. I lived in perpetualfear that the weight would somehow slip out and the whole thing would noseover..Gary BootheNX308MB
