I received a Model Avionics SkyTach a few days ago. What headspead should I be turning in Idle#1 at a hoover? I had two friends today shoot the headspead and it was 25-2600 TC of 100-50-40-50-100 PC of -8 -5-0 +5+10 Both of the guys discribed how the blades stopped by making adjustments to the tach.

2500 is way overkill. I try not to go over 2100 with mine.

raptor 30 gear ratio is 9.56-1 so take your os 37 the power band is around 18000 rpm / 9.56 and you get around 1880 target head speed go with 1900 and when your head bogs it will drop into the power band of the motor

no babe i swear i sold my other heli to buy this one :)

Also need to keep in mind Blade composition.Woodies will not hold up to those rpms for long if at all.

I love the smell of nitro in the morning..

RPM
Thanks I will crank it down tonight. This means my Titan x50 is probably off the chart since this is the Heli I bought the tach for in the first place. I will check it out after after I get it back together tonight, one bad Auto shortened the tail boom.

Thanks to all for the help
