If you're looking for all out 3D, I don't think you'll be happy with the magnum 70....but the 91 will make the plane extremely nose heavy. Heck, it will probably be pretty darn nose heavy even with the 70. If it were me, I'd use the 70. It won't be a true 3D monster, but it will have plenty of power and make an excellent sport/aerobatic ship.

I wonder if I should go with a 2-stroke motor ?
maybe .51 or .61
what do you think will be better and why ?

I have not bought the motor yet .

thank you.

Bigger,slower spinning props are more efficient for torque, wich is what you want for 3d and such.
I second Cubber. The Saito .82 is the same weight and size as the .72.

If I were using a 2-stroke (my Reactor has a YS .63), my first choice would be a Webra .50. Failing that, I'd probably get an OS .55 AX. The Webra weighs less, an important consideration for this plane, and has the same or better power as the .55.

How your Reactor is going with YS-63? Did you do any CG correction by additioanl wieght? How is the power of YS-63 for this bird?

I actually haven't flown it in over a year. I discovered profile planes shortly after getting the Reactor airborne and haven't touched it since. Heck, I never even got the chance to dial in the CG. If I recall correctly, it is a bit nose heavy with the 63. The tank in on the CG, however, so I'm sure that helps.



And at about 5.5 pounds, the 63 is adequate power, however I have a profile bird at 4.5 pounds with another 63......now THAT is some power. There are more pics of my Reactor assembly here if anyone cares to check it out.
