I15 Arms

[stepaside]

What kind of I15 arms are good for High Power? Drill Blank Or the millennium blank?

[RomanK]

Drill Blank refers to a type of armature shaft and Millenium refers to an armature blank design.

The arms of choice by many seems to be the older Intruder and newest M-2 blank arms from Proslot but your current and recurrent USRA 15A Nats champ, Brian "LAMO" Eardley, did it with the Koford Tristar arms. 38 degrees of timing seems about right as well.

Any of the above arms should be a good starting point.

M2 Hemis are the way to go 38 Degree gear 10:44
