I've been advised to get a 90 SE and would like to know what upgrades or changes are a good idea in terms of making it as reliable as possible.
i'm thinking of the tail rotor hub, clutch, cooling duct and whether the carbon boom and tail drive are as good and as reliable as the alloy ones.
also does anyone know why the canopy has been changed, is it aesthetics or flight performance? is it availablein the UK yet?

My understanding is that the SE is the upgraded one. The carbon tail is great. I was going to get the SE but the shop only had the STD version in, so I got that and the aluminum head. The SE already has that upgrade. The SE should be good to go. Although the paddles could use an upgrade.

The 90 SE flys great in it's stock configuration with no upgrades necessary except the paddles if you want faster cyclics. The new tail hub is very nice and I have been flying it for a couple of weeks now but I never really had any issues with the older hub as long as you were careful during the installation. I prefer the aluminum boom but I use the carbon torque tube as a matter of personal preference. I have not had good luck with the TT HD clutch as mine broke after only 20 flights. I installed a Quick UK HD clutch and it has lasted me over 300 flights and still going strong.

The new canopy design should give better FF performance because of it's slimmer design and it also looks way cool .

Do a search and you will find many tips on setup of the Raptor 90 to suit your flying style.

Thanks guys, tell me led is the new hub you're using a TT part or the quick one?
Also if the clutch failed so soon is it worth putting a thicker liner to close the gap on the original unit.
Does anyone know if the quick clutch is just better materials and design or a wider diameter so the shoe doesn't have to spring open so far

The new one piece hub is a TT part and I do not know the difference in the material between the TT clutch and the Quick UK clutch but the diameter of them is the same.

I know a few guys that have used the TT clutch and have not had any issues and then there are some that have had them fail after a few dozen flights.

I always make sure my alignment is corect and that I have minimal gap between clutch and liner. I was not happy with the stock liner gap so I re did the clutch liner with some paper behind it to decrease the gap.

Is the new hub metal or still in alloy?
If they haven't made a grip design that now uses thrust races in the grips, it's still only half an upgrade IMO.
I've never really had any problems with the original alloy hubs on the Raptor 60/90.
Have had a Raptor 30 V1 hub that threw a tailgrip with blade once:-)
I'd liked to have seen a proper thrust raced tail grip setup more than anything,with a metal centre hub for the 90's

My understanding is that the new hub is a one piece aluminum bit. I wonder if anybody knows the part number? Also, what are the part numbers for the aluminum mixing arms in the head that everyone uses to replace the stock plastic ones (for more cyclic/collective), and what main gear/pinion to get 8 to1? (91 t main with 11t pinion?).

PV0499 is the new stainless steel hub, for all Raptors.

rchaas,

You can't get an 8 to 1 ratio on the 90 SE. You can have 8.27 to 1 with the 91t gear and 11t pinion or 7.91 to 1 with 95t gear and 12t pinion.

The part number for the mixing arm is PV0295 but these have the same geometry as the plastic ones and you will not get any additional cyclic/collective. The best way to get more cyclic and collective pitch is to shorten the arms from their stock 41mm length down to 39mm and make sure they are in the inner hole on the seasaw.

rchaas,

In my Raptor manual the part number for the upgrade mixing arms is PV0295 but I do not think this is a valid part number any longer.

The part number that you need is PV0437-L for the blue anodized arms and PV0437AL for the silver arms.
