this is one thing thats frustrating in this hobby ... everything you learn is the hard way ... every person says something different and I usually find the right solution by damaging something.

I searched these forums and found many posts saying that the 12TZ should have only 0.2mm shim if running 16% nitro and once it has been run in. Now , I am told to add more shims ? sorry, but its really confusing

Also, with regards to the oil, I could not find anything specific on the manufacturer website and the guys at local hobby shop recommended to run 5% and 5% ... yet I am told something different again.

I appreciate all the feedback and help from you guys ... but its just frustrating because I want to do the right thing, however, I get so many different opinions that its confusing
