I have (3) three of these http://www.horizonhobby.com/products/HAN3011 (Hanger 9 3031's)

and two (2) of these http://www3.towerhobbies.com/cgi-bin...&I=LXCB28&P=ML (OS-F's)

I have a brand new FA-100 GK and am going to break her in this weekend (03/29/13)...............

My question: Is it OK and/or good practice for me to break-in the FA-100 in on the Hanger-9's 3031's and then switch to the OS-F plugs for the lastsequenceof 10 mins. during break-in (the last 30-40 mins.) and continued use of the OS-F's for duration of the FA-100's life.... or will breaking in the engine with a differentplugcauseany issue when I move to the OS-F's for ever....???

Or should I stay with one glow-plug thru-out.

P.S. Not sure if it matters, but I am going to break her in and continue with PowerMaster 20/20 YS fuel... yeah baby ! Going in a GP Revolver 70", btw.

Yes, I am anal, lol.
