Default Plane for a Rossi 90 Rear Intake Rear Exhaust?

Greetings,

I've got a Rossi 90 RIRE Airplane engine. I broke it in and flew it in an Escape and have been amazed at its performance even at low RPMs (11-13K) Now it is time to bring the engine to its upper RPM range and realize the full potential.

Have any planes to suggest?

Man it's hard to shoe-horn them into most planes. I have a few of them and haven't ever settled on a single engine plane yet. I'd try a old-style 60 sized pattern plane..maybe a King Kobra or something. Any plane that has a cowl is a drag since they really need wood beams to mount to...King Kobra has a cowl...

Finally have a plane to mount a pair of them in, a 85" Duellist.
Wood cowls so you can carry the mounting beams out past the "firewall"..which won't be there..anyway..

Glad to hear somebody else has seen the power of the RIRE Rossi 90..they are beasts!

Thanks for the replies, I was thinking along the lines of 2X scale Diamond Dust. Any thoughts?

Sounds like what the doctor ordered! What kind of speed could I expect with the Rossi 90 RIRE? Do you have any experience with the ARF? Is it easy to fit the RIRE onto the mounting rails and building a pipe support on the wing?

Look Here for some great info on the Vortex. If you can't find it there, shoot Bruce an Email, I bet he will tell you anything you need to know

Vortex too big to go fast? I don't think so.... (well maybe with a .90 2 stroke)

I saw a Vortex with a turbine mounted on top of it at the Superman Jet rally last year! Fast for a while until he hit a landing light on landing. That makes for an abrupt stop. It always looked like an accident waiting to happen the whole time I was there.

Yes, there is a lot of air to displace with a 4" thick wing so I don't think that it would be a sound breaker. I have a Rossi 90 which is rated at what, 5.5 horse at 22k? or in that neighborhood. It's been awhile since I read the specs. That should be enough to haul it around faster than most planes at the field. Granted it won't be like my duster, but like a big brother that is easier to see.

Default well

I think you need an OS-61FX w/quiet pipe and I would be happy to trade mine for that ole boat anchor Rossi!

I gotta get me one of those huh Dave?

A Vortex with a Turbine? Reminds me of the guy who put a rocket motor in his Impala-

Keep us posted,
james

Sorry James,

I'll have to call no joy on the trade. The Rossi may be a little heavy but they are like the little pink bunny, they keep going and going and going...

Does anybody have any experience with the Cermark Delta Vortex? Looks like a sweet machine. If it flies like the Diamond Dust it should be great. I get the feeling that the expected speed with the Rossi would be in the 100-125 range, at least that is what Bruce reports from the shop.

"Speedwise, I'm sure you'd be over 100 (maybe 125?) with unlimited vertical." BTE

Is what he wrote.

Even if it doesn't break the speed barrier, it looks like it could be a lot of fun.
