This is pretty exciting to me. I have thought about something like this, but these guys are making it! Hummel has a solid reputation for all metal part 103 machines. This looks very interesting. HUMMEL MULTICRUISER FAR PART 103 NO LICENSE REQUIRED- NO MEDICAL REQUIRED - MADE IN THE USA! |

Empty Weight : 245 - 252 lbs, Gross Weight 550 lb You get 298 pounds to work with.... How in the hell did they design an "all metal" aircraft with two engines that weights 252 pounds? What is the advantage of a second engine with a no pilot license low experience pilot when one engine goes dead? It seems multi engine flying requires more skill so let's put two engines on a plane built for the least experienced? |

A lot of experienced pilots fly part 103 ultralights because of the low FAA regulatory requirements. I know one retired ATP who flies one. He can't get a medical anymore, but he still knows how to fly. Clearly only a fool would try to fly a multiengine machine without multi engine flight training. |

Keep in mined that the lack of experience or ME rating can be designed out, by making an airplane where the blue line is below that stall speed (preferably below Vs0). Hummel isn't making a claim that they designed Multicruiser like that, but it's possible. However, it's virtually guaranteed that the OE performance of Multicruiser is abysmal. So, why would anyone want it? I'll let their marketing department answer that. But I'll note that the unavailability of Cri-Cri in U.S. market has been a long time topic in leisure and experimental aviation circles. Well, now, you have a Cri-cri at home. |

Still, an enclosed cockpit in an ultralight is a luxury, no matter how you do it The reason performance is abysmal on all ultralights is because the FAA mandates it, if you're going to adhere to Part 103.. top speed, HP, stall speeds, fuel capacity, it's all stipulated. You can buy an H5 if you want to built your light sport or experimental with better performance, but it comes with a lot more FAA rules. Would be interesting to see an "H5 multicruiser". Most prebuilt LSA aircraft are quite unaffordable for the average pilot, unless you go vintage. |

As far as I know, only top speed, empty weight, and fuel capacity are limited in Part 103. The power (h.p.) or stall speed are not specified in any way. Unfortunately, the dry weight limit is very strict - only 254 lbs. For this reason, it's very hard to find ultralights with 4-stroke engines. The most common of them is Legal Eagle. |

You're right about the HP but the power off stall speed is definitely stipulated. I had to look it up...I knew I saw it somewhere..here is it straight out of FAR/AIM.  |
