Ultralight with a DLE 222cc for engine ?
Guys....
Just a crazy thought.
Do you think the DLE 222cc is able to pull an ultralight aircraft ?
And if yes,
what's the max weight the airframe should have ?

What about the wing area ?
Also,
400lb MAX TOTAL flying weight
or
just the weight of the airframe+engine+equipment MINUS pilot ?[&:]

Also,
Mr Robinson,
how can we calculate the maximum weight ( the weight of the airframe lets say ) an engine can pull ,
if we have the thrust generated via a prop@rpm combo ?

UL max weight is 254 lbs. empty.
IIRC, Homer Kolb, designer of the Kolb series of ULs, first flew his with 4 chainsaw engines, about 5HP each, in 1956! He is in the EAA Hall of Fame.
The first popular ULs were hang gliders with chainsaw engines added, early '70's.

You're a lot more likely to get off the ground with something like the Rotax 447:
http://www.rotaxparts.net/scripts/pr...p?idproduct=33
It's about 40hp and of course has a bunch of gearbox options. You can swing up to a 66" prop at a more reasonable 2500 rpm or thereabouts. I've flown a couple 447's, good engines.
The DLE would be super loud too!

RE: Ultralight with a DLE 222cc for engine ?
True, but believe it or not, it's chump change for 40hp that'll crank a prop reliably on an airplane . Oh, and the gearbox is another $950 or thereabouts. you'll even pay a couple hundred for a prop.
Basically, take the cost of the r/c piece and add at least one 0 to the end - that's the cost of the equivalent in full scale .
I.e. take an R/C flat four 4 stroke like the O.S. at about $1700:
http://www.osengines.com/engines/osmg1320.html
add a zero and you're about at the equivalent in full scale (Rotax 912 series):
http://www.kodiakbs.com/engines/912ULS.htm
(actually this one is the 100 horse which is right at about $20,000 new)
When you get into complete planes, you need to add two 0's usually....

Would you trust your life with the DLE-222? Not me. The Rotax is proven and your life is worth spending the extra money on.

I "FULLY " intend to use a DLE-170 on my Exxtacy hang Glider for next winter !
For the money and weight, that engine will have More than enough power to push
my 168 squair ft glider .
Luckely i have a 36" gap bed Lathe, so i will machine a hub for a
three blade prop that has variable pitch. Much better power for
take-off that way, then relax for cruse .
I will need to takeoff and land on wheels however,(in dead air).
Notice the complete lack of legs beliw both knees on this launch at King Mt
Idaho last year. I got to 14K ASL on that flight. This was the nationals
compitition and i placed Last . ((sigh))
In the early 80's i was #4 in the world at aerobatics on one of these devises.

Also while on the Lazair, What was the purpose of having 2 props per motor? i could understand if they were 90o offset but they are behind the other. would it change much of the characteristics if they were 90o offset instead?

I bought a Lazair last year and I'm thinking of putting a couple of DA 150s on it.
