used as it was conceived (at this era),  it has good (enough) climbing performances.

don't forget that even F24R 200HP were classifed as 3 seaters in military use, considering 3 equiped pilots/crew members could only take place in an F24. (with full Equipment, maywest, helmet and gears, as well as boots, gloves, and seat parachutes)....and
interior lining weren't of leather at that time....avoid leather in F24 restoration, you may well spare 40lbs or more...




and she climbs well enough even flying on grass runway shorter than 700meters...

to have better climb, just use the "climb" propeller...designed for F24! It os really very efficient in this way!

using more powerfull engine, for such flying characteristics, is really a poor idea....thinking such characteristic is used only a few % of total flying time on such cross country travelling plane.




unless the plane is not the right one for such use (climbing fast), there must have been a casting error when choosing the F24!

'Mark D. -- Hell yes, it has been done. The F24 has also been STC’d for the 245 Jacobs. These conversions look a bit clunky, as the engines are quite a bit larger in diameter than the Warner, and the cowls don’t match the profile of the fuselage very well. The Continental is 6 inches larger in diameter than the Warner and weighs 150 pounds more. The Jacobs R-755 is 7 inches larger in diameter than the Warner and weighs about 200 pounds more.



I always thought the best engine upgrade for the F-24 would be the engine of the Nanchang CJ-6: the Housai HS-6 of 285 hp, a Chinese version of the Russion Ivchenko I-14 which had versions of 220 to 260 hp. Any version of these would be great. They are very close to the same diameter as the Warner 165 and 185. Think of it as sort of like a 9 cylinder Warner – per cylinder displacements are very similar. Displacement is 618 cubic inches. It is plentiful and reliable, arguably more modern, certainly more recent in manufacture, and relatively inexpensive, as are the parts, as they are, after all, military surplus, which correlates to “manufactured in relatively large numbers as spares”. It only weighs about 100 pounds more than the Warner. Remember, the Ranger is about 40 pounds heavier than the 165 Warner and the CG of the Ranger is quite a bit further forward. They put the battery in the back on Ranger-powered F24’s, and I doubt much more than that would be required to put the CG in the right place with a HS-6.



The furthest and most recent developments of this engine, the Vedeneyev M14P and M14PF make 360 and 400 hp respectively and are found in the newest and hottest akro airplanes from the eastern bloc. These engines have also been built into some amazing homebuilts and airshow airplanes by individuals in the US. These engines are currently manufactured. They have centrifugal supercharges as well as planetary prop speed reduction boxes, so they’re too long to fit nicely on an F24, and they produce more power than anyone in an F24 could practically use anyway. (I have seen one on a Stearman – tiny-looking and Uuuugly!!!, but it makes a great performer.) I mention the Vedeneyev only to show this engine family if far from dead, and there are plenty of parts and folks to work on them. Plenty of propellers are available also. The HS-6 is also common in the US as the CJ-6 has been a popular entry-level warbird over the last ten or fifteen years, ever since the Chinese air force obsoleted them and flushed them from their trainer inventory.



I know for many enthusiasts of the F24, engine swaps are sacrilege. I wrestle with this myself, as I own N28522, a Warner-powered 24; I like it, but it is a fairly wimpy performer. Since it is fairly original I will not re-engine it, but I often dream about the performance of an F24 with an HS-6. I think it would be a real sleeper hot-rod. With Warner parts being relatively hard to find, let alone people to overhaul them, If I was “bringing back” a derelict F24, I’d have a tough time not using an HS-6. It would require some engineering, but you could probably refer the FAA to those conversions to the R or W670 Continental or the R-755 Jake and show how much better suited to the F24 the HS-6 really is from a weight and size standpoint. Remember, if you put more area up front (cowl size) you affect long and lat stability. The HS-6 would affect stability not nearly as much as the Continental or the Jake do. Greater power itself is often a stability detriment, but I don’t think so with the F24, if you can keep the CG and the shape of the fuselage very closely the same. Nonetheless, with the attitude of the FAA today, you might wind up in the Experimental category. You’d have to investigate it completely before you commit to such a conversion, of course, and be certain you agreed with whatever certification you’d be able to obtain. Either way, it would be a great performing ship, and retain the original great look of the F24W. Even hide-bound traditionalists (like me!) can hardly argue with that. Up to a point, all else the same, excess power is your friend in safety.



Cheers!

I have a F24W project. It’s a mostly complete project minus the Warner engine.
So, I am looking for options and suggestions.
Any help would be appreciated.
