E-flite Power 90 Brushless Outrunner Motor, 325Kv: 4mm Bullet
Excellent motor. I use it with two series 4s lipo',2650 mAh , for an 8s equivalent 2.65k mAh pack. Unlimited vertical. Turns a 16in 12in pitch prop to perfection on a .46 U Can Do. I use the Castle Creations ESC rated for 8s lipo and have never had a problem with overheating or shut down. If I fly with a lot of vertical maneuvers I get an easy 6 minute flight with two minutes to land, more than enough for me. No vibration. Motor is barely warm. I printed my own PLA 3d print mount on my Ender 3 printer and it gets the motor out from the firewall about 2 inches which is a perfect match for the cowl. Bought a second one for another gas to electric conversion on a .60 plane.
