Hello All,
I have just received my ModelTech Magic 3D and plan to use a Magnum .52 Four Stroke. Love all the threads on RCU about CG and plan to mount battery way aft to balance the CG without adding any additional weight. My question is about mounting the Magnum .52 RFS on this plane. Any tips on down-thrust and Right-Thrust angles that have worked for other Magic owners with this engine combo ? Already beefing-up the firewall, so any tips or comments about this plane holding up to the extra vibrations of four-strokes would be very welcomed.

Also, will the APC 12.25 x 3.75 prop be a good choice for this engine ?

Thanks
