What other starter motors are available that do not beat up the starter adapters as bad? Thanks Kevin -----Original Message----- From: Lancair Mailing List [mailto:lml@lancaironline.net] On Behalf Of Kent Sent: Saturday, November 29, 2008 5:51 PM To: lml@lancaironline.net Subject: [LML] Re: Subject:,Starter adapter drive hello The TCM starter adaptors are stressed by the permanent magnet motors, like the Iskra brand and others. The permanent magnet motors have high starting torque and more importantly do not relax after being de-enegized. The start adaptor needs to be able to unwind a bit to totally disengage. Aircraft Specialties Services found it was being blamed for warranty problems that they knew was not their fault. So they made a cutaway starter adaptor and made video of the mechanism on a running engine. regards Kent Felkins Tulsa ----- Original Message ----- From: "Douglas Brunner" <douglasbrunner@earthlink.net> To: <lml@lancaironline.net> Sent: Friday, November 28, 2008 2:25 PM Subject: [LML] Re: Subject:,Starter adapter drive >I also had to replace the starter drive adapter on my IO-550 (non turbo) > after about 50 hours.
