Engines For Ultralights

[GyroJoe]

Well......

Well......

......and

.......so

.......yep

Where's those other 1,220 gyrothusiasts opinions
on engine choices for ultralights?

I found on the Aussie forum (it's probably somewhere here,
too) a rule of thumb formula for figuring the static thrust
for an engine (depending on the prop, of course).

2.5 Kg (x 2.2 lbs/Kg) per horsepower.

5.5 x 45 hp (Tim's engine) = 247.5 lbs. static thrust.

Even though I'm still in diapers, sounds like he might
make it over the tree tops with that.

Keep those engine choices coming.......

Regards To All,
Joe

P.S. Thank you Tim and Ron. I really mean that.
I'm getting an education here.

....If you happen to put an engine on that flys the gyro
faster than the 63 mph allowed

Thanks,

I just read that you can change the pitch of the
prop blades to set the maximum speed.

A Harley 88 cid motor v twin weighs 100-110 lbs...
would this be a good motor to use?

Wille, it has been my experance that a Harley Davidson twin cam 88 weighs close to 150 pounds. By the time you add a starter, redrive and exhaust the weight is going to be closer to 185 pounds. I believe that it is apealing never the less. I have often thought that the aircraft in 12 o'clock high sound like a gagle of Harleys. Thank you, Vance
