The 46 FX in my H9 Tribute 36 weighs 4lb RTF. It hovers at under 1/2 throttle with a very hard pull out. Rocket effect is nice too. I get around 22 minute flights on it. Very strong design, as I have inverted flat spun it into the ground. Picked it up and flipped the prop and threw it back up. For only 85 bucks, one really cant care too much.
