Paul Marsh  |  Jul 13, 2014

Strengths:
Different -that's the main reason to have one. Low profile, light. . .
Weaknesses:
Gets hot, lacking in power, unreliable, noisy (sounds like a bag of nails when starting/warming up). . . .
Overall:
Also have a 60SP, this is better, but only just, gets really hot - even cowling thought out, hardly any power - needs expensive 10% and gives me dead-stick landing practice. Won't buy another. . .

Strengths:
Low profile so will often fit inside the cowl. . . .
Weaknesses:
Weighs a ton, and the propshaft is offset 3. 5 mm from the "normal" position. Slightly cantankerous carb. And the support is via an on-line forum - I'd prefer to speak to someone on the phone.
Overall:
When first run, it wouldn't pull the skin off a rice pudding and was a bit of a liability. However, after having run it for over an hour, it's gained over 1000 rpm on a 14x6 and is now behaving normally; it might improve a bit more. . .

Andy Butler  |  Sep 21, 2008

Strengths:
Good quality, starts first time - every time - and it's British. . . .
Weaknesses:
None so far. . . .
Overall:
Take care running it in - I've put over two litres through so far and it's now just coming on song. It was fine after the recommended running in period, but with extended running it really gets settled and pulls like a train. Throttle response very smooth all the way up from idle to full chat. never misses a beat.

Michael Boland  |  Jun 04, 2008

Strengths:
Compact size, good 4 stroke + gear noise sound for scale effect, reasonable torque. . . .
Weaknesses:
Heavy, hard on con rods, carby is too high. . . .
Overall:
I have 2 of these, although only one is in a bird at the moment. Have already broken a con rod after only about 40hrs running, but a lot of nose overs and a few crashes (any motor can fail when stopped that quick). Produces some very strange gear noises on occasions but these seem to go with a bit more running. All the RCV's I have had reach paek rpm with the throttle only 3/4 open which to me indicates badly matched carbies.

Keith Flower  |  Jun 04, 2008

Strengths:
compact design leads to easy cowelling which conceals the engine to give a better scale finish. RCV engines I feel are quieter running than the OHV engines and above all this is a British product from a company with an international reputation. . .
Weaknesses:
Slightly down on power compared to other 4 stroke engones but this this is balanced by excellent fuel econony. . . .
Overall:
Grat engine for mid sized scale models. The history of sleve valve technology goes back to the golden age of British radial enines eg the Bristol Centaurus. . .

WOW
Malc. Nicklin  |  May 23, 2008

Strengths:
The Torque was found to be very high with very little change with size and Pitch of Prop. Good tick over down to 2,000RPM with an APC 11" x 6" up front. Very clean oil that is exhausted after running in. .
Weaknesses:
Strange feeling when first turned over by hand starting until run in then it's a matter of a couple flicks after a nice wet prime. A little oil comes from the front bearing but so what it shows that oil is getting through. . .
Overall:
Having started using model motors from the 50s up to today’s marvels both 2 and 4 stroke I was somewhat taken back with my very first RCV 58 CD motor. It had this strange feel to it when the shaft was turned and not much compression as you would normally get with a motor of similar size 4 stroke and I could see why then that RCV recommend the use of an electric starter to get these motor fired up. The motor was mounted in the bearers and plumbed up with the pressure nipple on the muffler feeding the tank and a 11” x 6 “ APC prop up front. On turning the prop over to give her a prime it took no effort to turn it over with the Chicken Stick to get the fuel up to the Carbie and into the workings but still very little resistance to compression.

Malcolm Bray  |  Jan 31, 2008

Strengths:
Very Torquey, sounds superb,T. T. 91 silencer makes all the difference. .
Weaknesses:
Engine develops a harmless "rattle" at idle after extended use. Require A LOT of running in. . .
Overall:
After many hours use engine is now bueatiful, idles nicely, powerful and can even start by hand now. 10% nitro+at least 2%caster mixed in with synthetic in fuel. . .

Alan Weston  |  Jul 14, 2007

Strengths:
none. . . .
Weaknesses:
reliability,bad starting,vibration. . . .
Overall:
I have been modelling since i was about ten years old(im now 51)and i can honestly say this was the most unreliable motor i have ever owned. Its now long gone thank god and i pity whoever bought it. I have since had hands on experience of two more 58s a 90 and a 120sp and can honestly say that unreliable running,idle and vibration have put me off RCV for life. Shame really, you pays your money and only the model shop profits,thank god for china.
