One of the big reasons is cost. The power plant is the single most
expensive componant in an aircraft and people are loath to buy 2 of them at the high price they fetch. Ultralights tend to have landing speeds in the range that an off airport landing is not as dangerous as their heavier and faster cousins. People fly them in rural areas and just live with the engine failures. A twin engine configuration also brings up the asymetric thrust issue which can cause loss of control below a specified airspeed. But your sentiment is felt by many, and the topic has been visited on many occasions here and never fails to stir up controversy. I've thought about the problem a bit and posted some ideas on my web site: http://inline_twin.tripod.com/ As for a cheap way to handle feathering props, I like the self-folding prop idea I've seen on some european ultralights. Regards "jic" wrote in message news:Y4JIb.106419$ss5.61293@clgrps13... Why are there no multi engine ultralight trainers? I have about twenty hours behind a 912 and two forced landings already. It sure would be nice not depending on a single powerplant. Are two 40 hp engines unable to do the work of a 80hp? |

With tens of thousands of hours flown and the average flight over 12 hours, I bet you can count Predator engine failures on one hand. |

By the way,
When they dredged up Gus's SpamCan a few years back, the switch was found in the "Off" position. Draw your own conclusions / conspiracy theories. Harry |
