Big props look good on the ground, but the bigger the prop the more the torque affect on takeoff is amplified. This plane does not have the biggest rudder in the world, so you'll have to be very smooth on the throttle when taking off. Another thing that makes the torque affect worse is the angle of attack on the landing gear. Using a bit shorter gear can help reduce rudder needed on takeoff by quite a bit. My 1.60 OS turns a 17X10 prop, not small by any measure, but I was surprised that the plane is not too hard to get down the runway straight as long as I bring in the power slowly.
