If you are running the OMI C SPEC you already need the HD clutch.
The CNC gearboxes work fine, the open boxes are safe now, just had growing pains. It's not really necessary, but it is easier to check the lash by nature of being open. ( No more greasing either)
You can remove the bearing block on your older clutch and replace with the Tempest bearing block and re-use the old clutch if you choose.
The other thing that comes to mind id the tailrotor pinion block has changed since your model was released, it's now a one piece unit.
As far as pros and cons for the machine;
Yes, they are stiffer (pro) and transmit vibration from any unbalanced item (pro/con both)
It is all Carbon fiber, and hence conductive, RF can be an issue.
it's lighter by nearly a pound, makes the power appear amplified, but does not penetrate wind as well in an auto.
I wouldn't trade mine for ANYTHING!
If you can get the kit, you get all new parts. The conversion requires you to use your used bearings, head, and links from swashplate up.
If you replace any questionable parts, it will fly for a ling while.
