RE: GMS engines......Good? Bad?
My $.02
I built an LT-25 and put a GMS 32 engine in it. Maidened it about 3 weeks ago after running 3 or 4 tank fulls of fuel thru it.
Just completed flight number 15 this morning.
Seems fine. Way overpowers the LT-25 (should of bought the GMS 25). Starts easy, idles fine and transitions to hi speed nicely. No dead stick (yet anyway). I did replace the glow plug with an A3.
I heard that these engines sometimes had manufacturing residue (metal chips, etc) inside that caused problems so I took it apart before installing it. Absolutley perfect inside with. very nice machine work.
I'm happy so far.
This Friday I'm going to maiden my 4*60 with a GMS 76. Hope it works out as well.
