A: Yes, we've had 60lb aircraft on it, but you do really have to tighten down the knobs to prevent the stand from sliding down. if the problem persists, replace the knobs with 3/8" nuts and use a wrench. Them maximum width for the arms to be straight us is 15" but I can make a custom tee bracket that can support a wider fuselage. Feel free to call or text me if you have any further questions.
