I use to disconnect the springs or move the hook to a hole with less tension, but for the last several engines, I just leave it in place. If you measure the current drawn by the throttle servo with the spring in place, the draw is minimal. It takes very little servo power to overcome the spring. There is some safety in leaving the spring in place. If the throttle linkage should fail for any reason, the throttle would spring closed.

I leave the throttle springs connected untouched nowadays. The small amount of poad on the servo does no harm at all. In fact the benefits are very high - such as
- The throttle returning in the event of a linkage failure.
- The preload given by the spring actually reduces the chance of a throttle linkage failure by keeping the wear, caused by engine vibration, on the linkage parts (Including the servo gears) down.
same here,just can't understand why anyone would remove the tension from the throttle shaft.
The minus? - the flight pack battery won't last as long but that is so minimal that it won't affect the number of flights you get between charges.
