Need info on rcv and laser 4 stroke engines

       Remove this ad - become a site supporter!

I would like to get info on these engines .

The laser looks like a regular 4 strokes but I am not quite sure about the rcv engines ...

Anyway I would like to get info on these engines (price, reliability, availability in Canada).

Gems or stay-away-at-all-cost ?

I beleave they are both British, I can`t speak for the laser, They look good, the RCV ,I have one, Stands for Rotory Cylinder Valve, 2 versions, one looks like a reg. engine while the other is inline great for in cowl consealment, it is also a 2:1 gear reduced, allowing a larger steeper pitched prop to be used. eg. with my .60sp rcv, a 14x14 prop can be used, they do take a lot longer to breakin though. You can get all the info on these engines at

Laser engines seem to be made to a pretty high standard. They encourage you to buy direct from the factory in England ( Not sure if they put out as much power as a Saito or OS, but they do specify no nitro in the fuel, so I doubt they would make quite as much power, though they should run cooler which helps in tightly-cowled scale situations. I am attracted to the no nitro concept because fuel is then pretty inexpensive if you mix your own. Methanol in 5 gallon tins is oretty cheap. It's nitro that's expensive and hard for the average citizen to get. Proctor Enterprises in the US sells Laser, and sometimes you can get a deal if you catch Proctor at a show. Anyway, I don't have a Laser yet, but their reputation is good.

I believe Blackfly Aero sells RCV Engines in Canada. They advertise in the MAAC magazine. The SP series I have seen run (the corn cob one) and they seem pretty good. The prop turns at half speed. Not an indication of lower power; just that a bigger prop than you might expect is required. Info at their website

Bryan Hewitt, a rcc member on here has at least 2 Lazers that he wants to sell. Perhaps do a search and pm him.

Hello; I have a Laser 100 mounted in a Salsa USA Taube. Of the 35-40 engines I have, I like my Laser the best. I ordered it direct from England. It was quite expensive, but IMHO worth it. I use a 15 x 8 APC on it, which is the prop that Laser recommend. It is the quietest engine at our field. It may not be as powerful as my Saito 100 (another wonderful engine), and may weigh a bit more, but it has been trouble-free for me. I use 0% fuel that only costs about $8 a gallon when I mix it myself. I like the fact that the cylinder has a nicasil lining, the same as my BMW. They use only the best materials and it is completely built and machined by hand, rather then cast or forged or molded. If you appreciate quality workmanship, you should have a look at one of these wonderful engines.

I have seen one of the RCV 58s run in a bench mount, so I can't tell you much about them. Interesting concept, but it makes a heavier engine, and the long mount might be difficult to find a mount for. I probably will buy one as soon as I see one for sale locally.
