ALDOVAR,
Here is how I look at your situation, sooner or later your boys are going to want to run more than one Remote Control operated engine, probably a couple at the same time. IMO I would save my money and 1st purchase at least an old ZW, Jim here on the OGR forum rebuilds them like brand new, I own 2 of his rebuild ZW's right now. I always advise everybody to have enough power to expand, so if I were you I would save my money and purchase 2 old refurbished ZW's one for each boy.
