RCV-58CD Question
 

I am looking for someone to share their thoughts and experiences with the RCV-58CD engine.
Recomend [sm=thumbup.gif] or not [sm=thumbdown.gif] !

I've seen Hobbsy's run and we've compared it with other similar engines. It starts and tunes easily. Is not tempermental. It doesn't have as much power as a Saito 56 or a Magnum 61 four stroke. When comparing with these other engines, it is closer to their power with a larger prop than the smaller ones.

Jim is right, it turns a 13x6 at 9,000 on 10% nitro, RCV recommends 10% nitro fuel with 16%--80/20 syn. castor blend lube. It is a very smooth engine, it will have some gear whine for about 15 minutes and then only very faintly.

RE: RCV-58CD Question
 

How would you say it compares to the power of a Saito 50?

RE: RCV-58CD Question
 

With the 13-6 on both engines, the 58 do better than the 50. With a 11-6 prop on both engines, the Saito 50 will run off and leave the RCV

So what about:


RVC58 with 13x6

VS

Saito 50 with 11x6

:D

I would say that the Saito would have the edge in speed, but the RCV will have the edge in brut force. IMHO, you are not exactly comparing apples to apples here. Apples to apples would be the Saito with any other 4 stroke of conventional design. The RCV shines head and shoulders above the rest in the power to physical size category. The RCV is designed to fit in small cowls where many other engines simply will not fit without cutting a large hole.

The RCV is also supposed to turn larger (read more scale like) props. If you combine a large prop and somewhat shallower pitch, you have just the right combination to fly your 40 size J-3 Cub that weight 6 to 7 pounds in a very scale like manner.

I have taken the same engine with a 12-6 prop and installed it on a 35 size stick weighing 4.25 pounds and it almost has enough power to hover it. On the same plane, my Magnum .61 4 stroke will hover it, but without much left. Same prop.

I must also mention, that theRCV is one of my favorite engines. Hot weather, cold weather 15% nitro and 18% oil this engine always runs flawlessly. Only a click or two to the needles, never a dead stick, and really takes a pounding. I had this same engine now on three trainers. (No not all of them mine... hahah) Both my wife, and two girls learned to crash um I mean fly with this engine and with reasonable care it has survived things where I have seen other engines die.

Would I own another... YES, but not for 3D work. Scale and War Birds...? definitely... Sport Flying? if you like to be different and not fuss with the engine and fly... Absolutely.

Just my 2 cents. I hope I didn't hurt and Saito feelings out there

Hey Blue, don't laugh at the Saito .50 with an 11x6, here's my Saito .45 turning a Graupner 12x5.
65 C thanks for bringing up the physical size part, from the top the .58 CD looks wide across the mount but underneath its the same as any other .50 sized engine.

RE: RCV-58CD Question
 

About a year ago RCV Engines sent some 58CD engines to several AMA clubs for evaluation. My club was one selected.

The engine is pleasant to operate, generally "User Friendly," but it's not a screamer.

Concensus is that it's a nice sport engine good for almost any purpose except racing.
