showcase and Review of Xtreme Upgrades for the Blade 120 SR

I have once again been given the pleasure of being a test pilot for Xtreme – this time with the EFlite Blade 120 SR, which is great as I did likewise on its baby bother the MSR. I have started this thread to showcase and review the Xtreme upgrades for the Blade 120 SR. The first upgrades that I have tested are the blade grips, anti rotation collar and head.

See below of initial specs/review and of course pics


The Grips are made from aluminium and the top portion is one-piece graphite that clamps onto the aluminium lower piece and uses a screw and bolt to hold and pivot the blades.
The grips come with all hardware including screws, white delrin spindle collars which attach to blade grips allowing pivoting on the head.

The anti rotation collar is all aluminium construction with mounting screw included.

The head is also all aluminium construction, comes with button, and head dampening rubber o-rings. I did not use the bushings from the stock grips, BUT I did transfer over the feathering spindle.



Weights (all hardware per unit included and weights are in GRAMS)

Stock:

1. Blade Grips = 2.97
2. Head = 1.2
3. Anti –Rotation Collar = .42


Xtreme Productions Upgrades:

1. Blade Grips = 4.11
2. Head = 1.83
3. Anti –Rotation Collar = .73


Total Difference(s) in weight from stock to Xtreme upgrades

1. Blade Grips = 1.14
2. Head = . 63
3. Anti –Rotation Collar = .31

Total Difference of 2.08 Grams


First flight Impressions:

I have only had a few close quarter indoor flights and won’t get a chance to really test out these upgrades until my clubs indoor gym session on Wednesday night. I’ll report more then.

The first 30 seconds of flight I had very minor TBE at first as parts are getting worked in and the blades were little snug in the grips – this is to be expected. After some minor adjustment this quickly went away.

The cyclics were very smooth and precise and the grips allowed the blade to track very well when hovering and slow forward flight. The linkages moved great through the guides of the head and anti rotation collar. The head seems to have cured my previous wobbling of the heli at transition from FF to a hover. However – this could’ve been a coincidence.

The aluminum/graphite looks great in flight and even better stationary. As stated earlier, I haven’t flown them much yet, but this will quickly change.


More to come; stay tuned

On the fourth picture the finish on the metal part looks a bit rough. Is this a sample or production quality material?

The grips are a pre-production model sample and wont look rough like that when released to the public, as far as I am aware anyways. Part of the issue is the lighting in the picture as well.

Thought so much. The bottom side already looked shiny, so I have the same faith as you, that the final product will be even more polished.

Regrettably I wasnt able to attend the indoor flying session tonight so I didn't get a chance to test the upgrades on a more open air concept yet.

Perhaps if weather permitting I can get outdoors for some winter flying :P

I really wish the 120 SR flew better in colder temps - its been a solid -14 + C here lately and the 120 SR can't handle outdoor flights even with a lipo sock.

Well I have been trying to get outdoors for flight tests, but the weather has really not been cooperating.

Been, cold, windy and snowy

I really wish it was still Summer

Is that the reason you decided to resurrect your Solo Pro?

But I agree, there have been a few nice days here so I could take a quick flight outside, and the cold temps affect the motors on my helis positively, so I've noticed, but my hands like some warmer temps better, and you always feel the risk of having plastic parts getting shattered should you crash in these conditions. Haven't had any lipo problems related to the cold. I think the fact that on the Solo Pro the canopy shields the lipo from direct airflow may help a lot with this, or the lipos I use are not much affected. I recently flew a Thunder Power 160 outside at around 0 degrees centigrade, in a Bravo SX, which has the lipo more exposed to the cold, and could still fly 4 minutes with power to spare, since I still needed around 60% throttle for hover, 10% more than in the beginning of the flight.

No its just been down for a while is all.

Yes the cold can make plastic brittle for sure - especially the fuse which is not something I like to crack.

Gotta keep my babies looken good.

Amen to that. I once cracked up a canopy during my first FFF with the SP, and with the wind, so it lost lift fast, and went down nose in. Felt horrible. I kept the canopy on though, and only replaced it when I learned to fly better, than put a new one on.

Btw, perhaps a little offtopic, but plastic gets brittle, I know, but does the same apply to foam, like on the wings of the Champ? I'd love to get up with that plane again, but I keep thinking about the wings snapping off midair during a loop because of the cold. Is that possible?

Yes Foam can become brittle as well.

I dont think the wing would snap off in flight unless there were previous damage/stress cracks.

Foam will give less when cold.
