There are plenty of ultralights in the world market but I do not recall seeing anything like our new Merlin Lite wing. 32 feet high aspect ratio with a huge 3-hinge slotted Fowler flap. We comply with the Part 103 stall speed and can easily set the prop to comply with the top speed.The only ultralight plane I'm aware of that ran afoul of the speed restriction was the Sadler Vampire. It flew considerably faster than allowed.
Yes, but it is the aspect ration of the rotor disk that determines the induced drag. You have a LAR (Low Aspect Ratio) flying machine. The Aspect Ratio of a rotor is one.My ultralight has a considerably higher aspect ratio wing than the Merlin Chip, my span is 23' and my wing chord is a mere 7" .... My comment was merely to suggest to work hard on the weight and not worry too much about the max speed limitation. That can be fixed easily later. Also, nothing in the regulation says it must be a BRS chute. You can use a pull out pilot chute and save even more weight and cost. Pull out pilot chutes offer the ability to throw out the pilot chute in a specific direction as opposed to a BRS type that is set by its fixed placement. That feature can be useful if the plane is in an unusual attitude or spinning during deployment. Tandem paraglider reserve chutes might be a possible avenue, where something rated at 220 KG might cost $1200 and weigh 5-7 pounds. You'd have to add the pilot chute, bridle, container, and all related attachment accessories to that figure which could make a big difference.
Yes, but maximum continuous power is in the definition of Light Sport only, not ultralight.They accepted that method with the LSA Carbon Cub.
I thought I was the only one paying attention. You are exactly correct with regards to ultralight speeds. I'm sure if it's really close that the actual speed might be tough to determine and no one would really care.Yes, but maximum continuous power is in the definition of Light Sport only, not ultralight.
(2) A maximum airspeed in level flight with maximum continuous power (VH) of not more than 120 knots CAS under standard atmospheric conditions at sea level.]
