I have seen the plane in southeast Idaho. It was flying last summer when I saw it.

The guy who made the plane(Predator Aviation, Stein knows the guys name) faked his death a year or two ago. Nobody knows where he is. He screwed many people out of a lot of money.

Thank God Mooney quit with the Porsche engines or my Boxster would need hamsters and a wheel.
I beg to differ with my dear friend Pierre, but this is not experimental aviation, its nuts!
Sorry for the rant, but I saw Dennis Miller in concert last Thursday and I've not been the same since!

Hey I need another test pilot! You up for the job?

For the 10 OK but 7...
The LS-1 Package is way to large and heavy for the -7. As a -10 engine to replace the IO-540 OK. The -7 is designed for around 200 HP, if you got the thing flying and could actually turn the engine up into the power band you would be over VNE in a heart beat. Read the designing section of the RV-10 on the Vans site. Van was concerned that as soon as he published the design HP for the RV-10 (260 max recomended) then people were calling in to ask if they could use a 300 HP engine! The plane hadn't even been built yet! Come on guys, I'm a dyed-in-the-wool alternative engines guy and I think putting an LS-1 on a RV-7 is just plain stupid. The result would be a aircraft in search of a catastrophic failure. Like the engine pulling itself off the firewall, or pulling the firewall off the airplane. Or the airplane going over VNE and fluttering the wings off. The part of alternate engine design responseability that we have is to use an engine that is as close to the design HP as we can. If you use something radically different in HP from the original YOU have just become the aircraft's head designer, act accordingly.

Predator flight characteristics
I talked to someone who knew someone (I know it is remote) who did some test flights in the Predator plane and I think the description of it's power off handling characteristics was "lawn dart".

Many use the higher hp engines not to get full hp but to get a good amount of hp while at lower rpms. Still the LS series is no good for the -7. Good fit for the -10 though. The rotary engines are pretty cool also.

direct drive?
The stock LS1 puts out 200 HP and 350 ft-lbs at 3000 rpm (according to
http://www.gmperformanceparts.com/En...4322&engCat=ls ).
Could it be possible to match it to a prop that would allow the engine to spin up to 3000 rpm for takeoff?
Weight might still be an issue, I couldn't find the weight of the LS1 really easily so I can't tell what the difference would be.
Any engine gurus care to say yay or nay?

SSSSHHHHHHH! I believe the government already outlawed lawn darts due to safety concerns. Could auto engines in experimental airplanes be far down the road?

My quote was really tongue-in-cheek since I wasn't even thinking of going there because this whole discussion is so old hat. Heck, I wouldn't be surprised if some guy isn't scrounging up an Allison V-12 to stuff into something like an RV-3...
Oh well, you can lead a horse to drink but you can't make him water...no...wait!...something like that
Oh well,
