| Aside from what Chuckie mentioned, there are a few popular (but largely unnecessary) upgrade parts:
* HyperHub or SE Hub: A redesign of the fan hub, one from Synergy, one aftermarket, both clamp to the shaft and reduce any fiddling required to dial indicate the engine. Only useful for people who don't like to or are bad at dial indicating.
* Hypercollar: This is the main mast collar, just below the bearing block. It's aftermarket, and is a clamp style, rather than set screw. The benefit is that it stays tight to the shaft instead of loosening up over time. Another advantage is that it doesn't gall up the main shaft - making replacing the shaft easier when the time comes.
* Hyperdrive: Again, aftermarket. This is a modification to the tail drive, and has a one-way bearing on it. It's supposed to run with less runout than the stock tail drive assembly. It's slick and elegant - but I have no idea if it's an improvement over the stock.
* Various main grips: The first plastic grips supposedly were a bit problematic for some. There are various metal 'upgrades', including the SE grips from Synergy. The "new" plastic grips fix the issues with the first plastic grip design.
* "Bonta Head": A flybarless head and grip set designed for the N9.
* Washout arms: Metal to replace plastic. Supposedly they develop slop slower than plastic arms.
* SE Bellcranks: Bling. I can't think of any real advantage to them.
* SE Head button: Bling. But I liked this one...
* SE anti-rotation guide: Not sure if it's bling or not, but I'm willing to bet that it is.
* SE thumbscrews: Smaller diameter, is supposed to be easier on canopies with holes that aren't perfectly centered.
* Tail grips: The stock plastic grips have been dinged for "coning" in flight, so various upgrade grips, including the SE grips, added an additional radial bearing to tighten the grips up.
* Tail hub: Longer tail hub is supposed to solve problems people were having with tail grips flying off of the hub mid-flight.
* Canopy: The first canopies didn't have a hole for the power switch. Newer canopies do.
* SE Engine Mount: 3 Parts, center, and 2 sides. Supposedly changes the harmonic of the engine to the frames, reducing fuel foaming. Also shiny.
EDIT: Added SE engine mount.
