Hi all,

I have a new OS 37 for my kyosho caliber 30 and i'm wondering how much i should be expecting from it. Am running +8 to -8 deg of pitch and using magnum 12% fuel with a standard kyosho muffler.

Things start to struggle at about +7 deg of pitch - is this normal for an OS 37.

If anyone's got an OS 37 then let me know how much power you can get out of it - what's your pitch/throttle curve like and how many turns do you have on the main needle? what muffler do you have and what pipe?
