Hi everybody!

Does anyone know if the OS 25 LA engine has an ABC construction or an ABN instead? The specs at Tower Hobbies say ABC for the 25 LA, but the specs for the spares (piston & liner) for the same engine give them as ABN. Also all the others in the LA series (except the 46 LA) are listed as ABN. Could it be that the 25 LA in original form comes with a chrome (ABC) plated liner, but the spares for it come in the nickel plated ABN form? Or is it that the Tower guys have just got it a bit confused. Would I be correct is assuming that the chrome in ABC makes for a better engine than the ABN, which is just a cheapie alternative with poorer durability? I have heard of the nickel being spit out after a while. All your comments are greatly appreciated.

Thanks!
