ORIGINAL: Cyclic Hardover
There is nothing wrong with it, I just feel its a bit much. I don't just slap it and go but i run a 2-3 tanks dialing it in which also helps in break in and then just fly it. The length of time you spend breaking it in does not mean the engine wil run well , if its not tuned right.
How many people do we see here spend weeks and months breaking in their engines too make sure everything is right. If they don't know how to tune an engine, whats the point?
-----------------
Actually, we see lots of people here complaining about this or that junk engine and about how they are going to dump it for an expensive OS. These folks do not understand that a ringed engine takes a while to come in and that it is not just plug-n-play, UNLESS it is an OS ringed engine. However, I do not see many old OS ringed engines around that are still running on the original ring, as I do with Super Tigre, Enya and a few others that use rings made of harder material.
Many ringed engines, when they are not broken-in, will overheat and quit. If you do a survey of all of the posts here that complain about this exact thing, the picture becomes a lot clearer as to what is going on. Insufficient break-in time/procedure and too much nitro in the fuel are the two biggest mistakes that newbies make. One can buy an OS with a soft ring and get away from this syndrome, but then their engine's ring will not last as long as those that take a longer break-in. You can't have it both ways.
