Welcome to the Culver Aircraft Forum

I installed the aeromatic Propeller on a hopped up 90hp Franklin engine in my Culver Cadet LFA. Because the propeller was set at the factory for a 90hp Franklin engine the engine was running at 3200rpm and level flight was 140 knots. Red line is 2500 rpm and I need to perform some flight testing to provide the factory with data that can be use to determin the proper settings on the propeller. I will do this as soon as we get better weather here in South Carolina. The crankshaft was cut off to 1 inch from the flange to fit the propeller hub.

I would be interested in buying it and trying it on my Culver cadet if it would fit the flange on my Franklin 199-3 engine. The smallest prop diameter for our Culver Cadet is 68"and if I wouldn't be unable to get a FAA approval I might be able to buy another set of blades for the prop that could be approved. If you sell it what would be the price?

Would you consider selling your beech roby prop?

The first is a fly-by my home. The second one is a Dart That Ibought in 1952 and restored in 1955.

Thanks for your interest, I borrowed a digital tact form our local AI and comfirm that the tact is correct. I flew 2 magnetic courses at 90 and 270 degrees and comparing my average airspeed with my GPS at 3ooo feet at 120 knots indicated and both of the averages were within a couple of knots. This is the Culver from Wisconsin the owner before then had the engine torn down for inspection do to a prop strike and at that time the high  compression pistons were installed. While in Wisconsin the engine was certified as not airworthy due to prop strikes. I disassembled and truck the airplane to South Carolina, I spent 3 years overhaul the engine, and rebuilding the airplane. Now I am looking for a certified prop new or used.
