TJ Pro governor on century hawk pro?

[skypup]

I am trying to add a TJ Pro governor to my Century Pro as I build the kit. I got the governor and optical sensor before I realized that the hawk uses a two stage transmission. The instructions say to place the magnets out 23mm from center. How critical is this measurement? This measurement puts me out on the very edge of the bell. I also have an optical sensor. It says to put reflective tape the width of the sensor. That is wider than the space between the gear and outer edge of the bell. Please see pic to visualize what I am talking about. Any help is appreciated

mount to the fan.

The fan sits directly on top of the pic above. Only about 1/4" protudes all the way around beyond the diameter of the pic above. If tape was located there it would not allow for the optical sensor to scan its full width.

I guess I can't offer anything on this one, except to ask why you want a governor on a 37 in the first place?
I flew mine on curves for a lot of years with no issues.

I'm with Wayne on this one. If you are flying the PRO and even wanting to do some mild 3D with it, just adjust your throttle curve and pitch curves to match. It will do well without a governor.

If you are really wanting to use the governor, you will probably have to fabricate a longer mount when gluing the magnet to the fan or like Wayne said, glue the magnet to the clutch bell

Thanks guys. I started with nitros 10 years ago. After switching mostly to electrics and using the governor feature I really liked the way they flew. I have come full circle back to nitros thought a governor would be nice. I realize that pitch and throttle curves can come really close to constant rotor speeds but thought that this might be a nice way of achieving that.

You might be better off going with the magnet and hall effect sensor method and bypass the optical sensor for this application.

I and other flyers at our field mount their gov magnets to the clutch - dead easy and works a treat.:)

Have you found it necessary to balance the clutch? Are you attaching two magnets. Thanks for the comments.

[GyroAl]

I have done it both ways - one magnet and two (one reversed) for perfect balance and found it made little difference. Because they are so light and so close to the center of rotation, which itself is so close to the front bearing (no moment arm of consequence to work through) that it is of little consequence.

Thanks for the information, it is greatly appreciated. Based on your experience I may just try one magnet. With one magnet is magnet polarity an issue?

[GyroAl]

Magnet polarity is always important.

When using one magnet, be sure the polarity of the magnet is correct (gives you a reading).

On a two magnet installation, be sure only ONE of the magnets give a reading.
