Has anyone used or considered using this redrive???
Looks like the one these guys are using: Quiet Aviation - Experimental Aircraft and Powerplant Research, Design and Manufacturing
The price is certainly fair compared to aviation redrives and it probably has a lot more hours on it than many other designs. Has a damper and looks dirt simple.
Any comments on the design?? It will be used in a pusher, so I think the bearings are all good. But any other thoughts or concerns???
I have looked into it. It can be used with any Chevy big/small block v8 or 90 degree v6. It has 2.0 reduction ratio and has had no failures in twenty five years of use on airboats. They get more use than any airplane. It is a very stout unit with a reverse rotation. No different than using a low time certified reverse companion from a twin. They're only $2195 and you supply the flex plate for attachment to the engine. They will attach their resonance absorbing coupler to the flex plate. I am using the Ecotec 2.0L supercharged engine and am fabricating and adaptor plate for this combination. My PSRU is on the way. I'll have pictures of my adaptor plate and the PSRU attached to my engine in the cradle I am building with a mockup of my firewall so that I can build my engine mount. Blaine Anderson
Rotator 1.53:1 gearbox from Panther Airboats. $2650+shpg. Hundreds in service, very reliable, 1000hp rating, about 70 lbs w/ soft drive coupling. 12" long, C-to-C crank-propshaft is about 5", Prop flange is LXL (4.75" w/ 1/2" bolts). Buick/Olds/Pontiac + Chevy bolt pattern. Don't tell 'em its for an airplane.
FYI - amongst the airboat crowd these Rotators have a MUCH better reputation that the Precision gear drive described above, and are available in many different ratios.
Niiice looking engine.
