Hi,

Recently l bought a Evo50. l used ~ 4 tanks of fuel (AT Racing: 15% nitro 20%oil) to break in.

After that, l was forced to set the needle to about 1/2 turn out from fully close or a few more clicks out in order to have enough power to lift off.
This is not right l guess becase as a new engine, the needle shouldn't be only half turn out for 15% nitro fuel.

If l make it to 3/4 out, it produces huge of smoke and doesn't want to take off before 75% of thottle and it sounds very rich.
then l tried to use a different fuel (10% nitro 20% oil), the different is another 1/5 turn out compare with AP racing fuel.

l'm not sure this problem is caused by the fuel or what, but when l tried different fuel, it has no big difference on the needle setting but only around 1/5 turn.

Anyone is flying a new Evo50 here? what is your engine setting?
Or could anyone give me an answer why my engine is running so lean?

My pitch curve is -2, 2, 5.5, 7,9
thottle is linear from 0-100%

Thanks in advance

Edmond
