1. [TowerTalk] Rotor Stripping Gears? (score: 1): Author: CubexCo@aol.com; Date: Tue, 28 Feb 2006 13:20:27 EST; This sounds like a typical Hy-Gain rotator failure. Is that right? With the current worm-gear drive rotators (e.g. Orion, BigBoy, AlfaSpid), they won't suffer the same fate. That's why I'm really rel; /archives//html/Towertalk/2006-02/msg00404.html (7,625 bytes)

(score: 1): Author: "Rick Karlquist" <richard@karlquist.com>; Date: Tue, 28 Feb 2006 10:46:39 -0800 (PST); Another idea I was told about protecting rotors was to mount the rotor lower in the tower so that a longer mast could be used. This is supposed to act as a torsional spring. The concept is apparently; /archives//html/Towertalk/2006-02/msg00406.html (7,928 bytes)

(score: 1): Author: "peter.voelpel" <df3kv@t-online.de>; Date: Wed, 1 Mar 2006 15:59:43 +0100; I learned it twice that worm-gear drive rotators also loose their gears. Two of my Prosistel PST2051 failed with a beam of 0,9m² at 10m height and only 60km/h wind gusts at that time. The worm a; /archives//html/Towertalk/2006-03/msg00004.html (7,854 bytes)

(score: 1): Author: "SJ W3TX" <superberthaguy@adelphia.net>; Date: Wed, 1 Mar 2006 13:13:35 -0500; Typically two stage worm drives cannot be easily backdriven. But I had two occasions (with the very hefty Boston gearbox that drives my Big Bertha) where the force from 90+ mph winds either "backdrov; /archives//html/Towertalk/2006-03/msg00013.html (7,796 bytes)

(score: 1): Author: <ve4xt@mts.net>; Date: Wed, 1 Mar 2006 13:09:55 -0600; This is all a very good argument for an Alfa-Spid style of controller: mast slips, adjust the controller. Period. No climbing. No pinning. No stripped gears. (At least until the slippage is, I think,; /archives//html/Towertalk/2006-03/msg00014.html (9,935 bytes)
7. Re: [TowerTalk] Rotor Stripping Gears? (score: 1): Author: k2qmf@juno.com; Date: Wed, 1 Mar 2006 14:23:35 -0500; That's the same for the M2 2800. However, once you make that adjustment to the controller you loose some rotation in the direction of the slippage. You can't have your cake and eat it too... 73, Ted; /archives//html/Towertalk/2006-03/msg00015.html (11,140 bytes)
