What does everyone think about the new style throttle spring?

Sample size of one: I like them so far. They were pretty quick and easy to install, and it's one less thing I need to worry about breaking.

Torsion Throttle Springs

I've had mine in for almost a year and about 90 hours now. They are fantastic. So glad to have them. They took an RV-12 trouble spot and totally eliminated it as far as I can tell. Thanks to the Van's engineering staff...........Tom

Doubling the "N" to 2, and maintaining a 100 % approval. :)

For those that have installed the new SPRING 00002-1 springs what was the torque kn the bolt? Have perused the Rotax maintenance manuals and cannot find the torque.

TIA

Found it ..... 44 in. lbs.

The springs were designed to closely mimic the springs that have been supplied with the throttle control by McFarlane (hopefully minus the vibration induced fatigue failure).

The RV-12 fleet is pretty good size at this point and other than a higher failure rate of the springs than should be expected, they have generally given good performance.

The cables on the RV-12 throttle control are not much different than those used on motorcycles or bicycles, which have to be maintained to some degree.
If they are noted to be developing some friction that wasn't previously present, they can be lubricated with spray lube, and that usually restores them to the way the were previously.

Scott, Do you spray it into the cable sheath? How and at which end??
