It does not matter what the angle of the rotating disk is with respect to the earth's gravitational field. It is measuring the rotating mass imbalance with respect to its rotational center axis. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Diamond Katana DA20-A1 Rotax 912 F3 Don't worry about old age... it doesn't last very long. - Anonymous Read this topic online here: http://forums.matronics.com/viewtopic.php?p=388322#388322 ________________________________ Message 2 _____________________________________ Time: 06:24:43 AM PST US Subject: RotaxEngines-List: Re: Prop-Balancing a TD From: "Roger Lee" I'm with Thom, I to balance props and have owned a helicopter. The angle won't make any difference. It is the rotating mass. You do not need full in flight rpm. I use 4800-5000 on the ground to balance. This depends on each persons prop rpm setup on their individual plane. The balancing instrument doesn't care because you just plug that number in and it gets divided by 2.43 any way because we have the gear reduction. -------- Roger Lee Tucson, Az.

(Central Colorado) .... Many active FBOs with repair stations offer dynamic prop balancing. They are getting more and more common as the price of equipment comes down. If I was doing mechanic work even half-time, I'd buy one but I'm still trying to be retired and only do actual work on other's airplanes once in a while. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Diamond Katana DA20-A1 Rotax 912 F3 Don't worry about old age... it doesn't last very long. - Anonymous Read this topic online here: http://forums.matronics.com/viewtopic.php?p=388325#388325 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
