I'm doing some research on what kits are available that are a twin-
engine design. I'm looking at possibly building and was curious since Google finds the obvious but didn't want to wade through 20 pages of stuff to find the non-obvious. Thanks. -brad walker |

The Cri Cri. :-)) Economical on gas too:-)) Roger wrote: I'm doing some research on what kits are available that are a twin- engine design.

I think it would probably need to have tip tanks and wet wings, though! :-)) -- Jim in NC |

In the end, except for a few special cases like the Cri-Cri or the Air-Cam, I doubt that there is enough of a market to develope a kit. Basically, if you demand the ability to maintain altitude with one engine inoperative and you eliminate the constant speed props that make multi engined aircraft competitive; then you make no gain in speed or payload compared to an equivalent single using a climb prop. You do gain usefull load, but it goes into added fuel; and you gain gross weight, but it goes into the additional engine, fuel, and structure. Alternatively, if you add in the costs and complexity of the parts that normally make multi engine viable, such as constant speed props; then the cost and the build time increase dramatically. In the end, a used and type certified twin makes more sense--unless it simply does not exist for the proposed mission. Peter |

My goal was a personal airplane that could carry a motorcycle weighing about 600 pounds. Hoisting a bike this size in through a side door didn't look attractive so I wound up with a sort of baby C-130 with two engines and a tail ramp. For economy reasons I really wanted a single but the geometry just gets really weird. Any cargo that heavy has to go on the CG if you intend to be able to fly without it. With the price of avgas these days, it makes more sense to just ride the motorcycle to the destination. Bill D Bill Daniels |

Thanks. -brad walker Hi Brad, the big question on my mind is WHY? To me the why nots include: - more cost - more complexity - more maintenance - more fuel - and unless it can get you home on one engine... LESS safety. |

It seems that gets you a fully assembled certified 4 place IFR twin. I don't think anybody is going to buy one of those twin kits, are they? |
