My oh my, I didn`t know until now how difficult and complex it is to choose a plug for my engines, it is almost rocketscience it seems[sm=lol.gif]
I run OS F in all my fourstrokes, they might cost a $ more than others but so what? they last forever, I think I have never blown one of those.
In my twostrokes I use whatever I have at hand, mostly OS 8, 5, 3,also the F, Towerplug, Sirio`s, Rossi`s, Mc Coy 59, ASP, and propably lots of others. After a needle tuneup I can hardly tell the difference between them in the air or on the ground (car, boat)
I did some peak rpm testing a couple of years ago and in my engines rpm never varied more than max 300 rpm peak no matter what plug I used, so I think for casual sportflying it really doesn`t matter that much
That should clearly indicate that with the approaching winter most of us have got more on the talking than on the
building and flying side of the life. At least frankly I feel so... and I fully agree that in many cases it is very
hard to tell which plug is used if the fuel and the engine are having some kind of "common sense set-up" proportions,
i.e. if we stay away of the extreems... It might be good to agree with some of the earlier posts about What
each type of enigne wants, i.e. to pay some respect to those who built the engines and wrote the manuals...
I am afraid some of them are looking with pitty at some of the statements at RCU and let us talking endlessly
here without even writing a single word (at least I know one guy like that from a very advanced RC engine
making company; he is even wandering how we can spend so much time & money to re-discover the Universe ...
How is the weather in Norway ? Here we got already the first snow flakes but still is above the freesing
point and ... I keep writing instead of flying ....
