I like your engine. Nicolas likes the lower weight of the 912's and 914's over all of them.
He really does not like PRA 31's Lycoming O320 and want us to put a used 912 or 914 that he can buy in Europe for much less money than a new one or a used one in the USA as there are more of used ones for sale in Europe.
How much does it weight Joe.. The Lyc o320 weighs 248 lbs.
There is another customer building a two place and he's using the Yamaha so once both are build we should be able to compare the fuel burn and performance to help others decide with is best for them.
I also forget what the Yamaha weighs does anyone else remember?
Hi AbidWhy do you want to put engines in that the Gyroplane was not designed around?
Lycoming is very heavy. He is right. Get a used 912 or 914.
That was my thinking too and we hoped we could make a heavy lift trainer as a couple of our members weigh 350 lbs.Boy, a lycoming would be hard to beat over any engine used on a two place gyro,the
reliablity and direct drive would be more than worth the extra weight of the lycoming.
Everyone has their own reasons for choosing an engine. I feel Joe will have a very nice gyroplane when he is finished. Ernie has had considerable success with the engine Joe has chosen to power his tandem.Lycomings also are air cooled engines which is bad news in a gyro. Gyros often fly in the high power but slow fligh regime which puts a lot of thermal stress on the engine since air cooling is not very effective when going slowly. I have a hunch that thermal issues will be your biggest problem with a Lycoming on a gyro.
I think that is because the price is so high as Jim only sells NEW O320's. I can buy used O320's for 5,000 dollars with 1500 hours left on them all day long!""Sportcopter II has a Lycoming IO 360. ""
True, but it's not a common machine - no news since machine #008 was registered a few years back. Bear in mind the Rotax gyro machines total over 3,000 examples.
