PREDATOR - Actually an OS 46 is really pretty good choice if your just getting into 3D. I had an OS 46 AX on mine when I first started and liked it. However, if the 3D bug bites you like it has the rest of us, you will quickly want more than the 46 can provide.

These planes land and and takeoff really easy,,, actually easier than alot of trainers. Just remember to keep a little "UP" elevator to you reach flying speed, which isn't alot. They float and almost hang when landing even into a 1 to 2 MPH wind. You'll like them, their a blast. They make me look like a better pilot than what I really am, to be honest.

It's up to you really. If you already have the motor, I would put it in and go fly and learn 3D, in adition to spending alot of time on a Simulator if you have one.

To be honest, about the time your ready for a new airframe, that would be a good time to move up to a bigger 2 or 4 stroke. Someone just said that the OS 91 is about the ultimate and I tend to agree, but a Saito in the same size class would work too I think.

I have a spare airframe built and ready to go, and I'm about positive I'll be sticking the OS 91 in it.

Have fun,,,,,,,
