Not too much information, but Spartan is working on their new governor, incorporating a mixture control, and a collective management features all into one box. The collective management feature works as the following, “The iGV will use the target rpm to manage the throttle as you would expect. Once the engine has reached it’s maximum output and HS is still sagging, the system will then reduce collective to maintain the targeted rpm setting. All indicators are that you are better off maintaining HS vs having a lot of pitch in the blades and lower HS.”

Looks interesting, and waiting for more information to become available.

Now showing on the Horizon Hobby site, is the Spektrum AR7100R Rev Limit RPM sensor and bracket assembly available separately. Currently not in stock (which is Horizon’s way of saying “not yet available”), the site shows availability by mid-September 2008.

The Align T-Rex 700 uses a pair of clutch bell mounted magnets for the governor sensor instead of the usual fan mounted magnets.  It will be fine if you are running the Align governor included in the box, but if are like me, you opted for another governor, you will need a bit of work to fit the governor sensor in.  This mod will work for governors like, Throttle Jockey Series, ATG, GV-1 and a whole bunch of others.

All you need is:

• 1x 30/50size sensor mount (do take note that some 50 sizers are actually using the 90 size sensor mount, we need a real 30/50 one.)
• 1x Small saw
• 1x sensor
• Some shrink wraps and cable tie.
• Some C.A, i.e superglue

1. Prepare/Cut the bracket to size.

The RCE G600 Governor comes standard with the 700N kit. It is also available as an option for a budget governor.

Lets take a look at the governor…
It comes with a very small sensor mount that is a perfect fit for a 700N. It should work well for other helicopters that are using clutch bell mounted magnets. With a small mod of changing the connector, the sensor can work with other governors like Throttle Jockey series and ATG.

Not too long ago, Chance on the Align forum did a Governor gain vs actual rpm for the G600 on JR PCM, Futaba 1024 and Futaba G3 tx/rx. I have done a tiny bit of translation from the original chinese version to english. [ click here to see videos, photos & rest of story ]
