My Posts This: Topic Forum | Hi Guys! I need some help!
I have been runing the NR57 with an OS A5 plug and Enya 3. With both plugs I had tons of power, runing very consistant and temps about 51/54 C messured on the back plate.
The problem is that I burned both plugs in less than 15 flights.
Now I'm using the Novarossi number 3 but after a couple of minutes of flight, on the ground, the engine start rattling. If I open the low needle, the sound become very constant but when I open throttle, the engine stops. The temp with this plug is about 55C, the main needle is 1.8 opened and the low needle, I don't know, I just hear the sound. Using 20% nitro, 20% oil and 0.4 shims.
The question is: If the temp was 54C at the end of the flights and I burned 2 plugs in about 15 flights, what is wrong with my setup??
Using the Nova 3 plug, could I lean the main needle and get a leaner mid range?
Thanks in advance.
BTW I'm interested to know also, How much percent, the main needle can affect the mid range and how much the low needle!

, throtle's stuck.... I was gonna 3d it to keep the load on the engine..... but I noticed too, the boom support is dangling loose also..... It might hit the main blades...... All I could do was pitch pump it, to keep it loaded...... Must be over 5 min till it ran out of fuel..... Next day I try to fly it again but it just won't make power it used to.... I took it off, open it up, I found the ring was cracked....
