I have used small OS 2-stroke engines for many years. With no scientific records
kept, I have an impression that the .15LA and .25 LA seem more likely to suffer
flameouts in flight than the .15CVA and .25FX engines. Does anyone else have any
experience on this issue?
P.S. Please don't bother to tell me that every model must have the heaviest, most
costly engine that can be bolted to the firewall. Sometimes the LA engines are just
the right size.
Back to the topic at hand here.
The 15LA and 25 LA are just fine for the job they are intended to perform. The only people that I have seen have problems with the LA engines were the ones that refused to use a suitable fuel such as 10% nitro with a healthy supply of castor in the mix, and those that try to tweek the needles too much, and those that insist on using an unsuitable prop, the list goes on and on. Frankly, I can say the same for many other engines out there as well. Bottom line is the LA engines are inherently reliable and durable when properly fed and adjusted and proped and pluged. They do not and never will have lots of power but they were never intended to. Keep in mind that I am not a huge OS fan, but the LA series does what they were intended to do.
Other engines that fall into the same category are the Thunder Tiger GP series. I know they make the GP 25 and not sure about the 15, but they are equally reliable. Enya used to have some bushing SS engines that were small, I had a 25SS and 30SS that were great, could not kill it.
Hope this puts this thread back on topic.
