I'm not too familiar with electric set-ups, I just got a Reactor by Great Planes. I have a Magnum 70 4-stroke that I could put in it with maybe something around a 15x6 prop? I imagine for the best 3d performance an electric setup is best but I don't know much about any of it. Would a Magnum 70 be plenty or should I look into electric? If electric, what do I need to look towards as far as motors and ESCs?

I would think the Magnum 70 would work just fine but the 15x6 would be too much prop, more like a 14 inch prop or even 13. On the Saito's I've found that the 13x4 works great on the 72 and the 14x4 on the 82.

I have a reactor with the magnum ,70 and the 13x3 is a perfect prop! The plane is a machine!!!!! If you cant tell I LOVE it!

The 13x3 seems low pitch, is it an APC? Have you tried other sizes? How well does it pull out of a hover? I would have thought a 13x3 would wind the magnum out too high. I was thinkin of a 14x5 maybe. Also, what servos did you go with?

Im sorry I ment 13x4...

MMM...What about a Magnum 91 FS? I just happen to have one and it's presently homeless. It's only ONE ounce heavier than the 70...Anyway, how good does this plane KE? The reason I ask is because I had a UCD3D 60 and it was terrible, same as the Twist 60, and I wonder if the Reactor's design is any different.

I only have a handfull of flights on mine. (still try to work the bugs out with the engine and other stuff) but it seems to do pretty good at KE. I didn't find any tendencies to couple. I'll check it more on Monday.

The Reactor is very good in KE. I run a 13/6 on a YS63 seems to be a perfect combo.

All is rccomend a 4stroke.
But how will a os 50 sx work in this plane?

have a 55ax in it w/ a 13x4 and its perfect..12x6 is good too..k.e like no tomarrow. unlimited vertical[X(]
