Review of Xtreme MSR Upgrades
I recently been given the chance to test some after market upgrades from Xtreme Productions that have been manufactured specifically for the EFlite Blade MSR. I received the parts today and upon initial inspection, they appear to be of great quality materials and the fit and finish is very nice as per Xtreme's reputation.
I received the following parts thus far:
1. Single Cell 3.7 V 15C 150 MAH Li-po battery
2. Aluminum Black Finish Anti-rotation collar
3. Aluminum with Black Finish Upper Head
4. Aluminum Swash Plate
(This tester is gold color, but final version should have black finish)
I have yet to outfit and test these parts on my MSR, but upon closer inspection of the parts, as said earlier, they are well made and are free of any burrs or any other manufacturing defect of quality control issue that might cause issues. The swash in particular, is very well made. while it is a bit heavier than stock, it is very well built and incorporates the use of a very smooth bearing system much like the larger swash plates Xtreme makes. The swash also has the dual swash settings much like the stock swash. Measurements are to come later.
Stock vs. Xtreme Weights of descripted parts (Grams) with difference in weights given to which is heavier.
1. Swash Plate
Stock = 1.17 Xtreme = 2.06 Difference of = .89 Xtreme
Stock Eflite 150 = 4.48 Xtreme = 4.30 Difference of = .18 EFlite
Stock = .30 Xtreme = .38 Difference of = .08 Xtreme
4. Anti-Rotation Collar
Stock = .12 Xtreme = .20 Difference of = .08 Xtreme
As displayed above, the Xtreme parts are a little heavier than the stock parts, in particular the Swash has a weight gain over stock of .89 grams. However, if the user were to use the EFlite 150 Li-Po, they would save .18 grams by using the Xtreme Battery, which I will add is also shorter and wider than the EFlite 150 Li-Po. The Xtreme Li-Po is tighter in the stock MSR battery tray vs the EFlite 120 or 150 Li-Po but it does fit. Its approximately the length of the EFlite 120 Li-Po.
While, I have not yet tested these parts; I am impressed with build quality, construction and fit and finish which I have become accustomed to with Xtreme Productions. Stay Tuned for installation and flight report.

Maybe just an optical illusion due to thicker arms, but looks like the swash might be shorter... Interested in your measurements here as if true that would be exactly what I was hoping for from xtreme all along! The helidirect swash is nice, but throws are exactly the same as stock... I would like a performance swash!
Need some new batts too so will pick up some of those if your review is positive.

Okay did some measurment on the swash and battery. Here are my findings
Stock swash arm length = 12.24 mm
Xtreme Swash Arm Length = 10.52 mm
length = 44.17 mm
width = 11.10 mm
thickness = 5.69 mm
length = 38.14 mm
width = 11.35
The swash due to shorter arms should have more or greater cyclic travle vs stock. I have since installed the parts and am using less aggressive awash settings. I haven't flown much yet, but I think I need new blade grips as it will hover briefly then go into TBE. I played with the blades and grips a little and got it to fly better BUT still a little TBE. So I will have to get more grips, install and retest later. I can say though that the parts were easily installed and fit perfectly. Despite my MSR still has TBE I do feel they the awash has more cyclic precesion over stock. I hope to upload pics ect later tonight.

Thanks for all the specs
Theres some good MSR specific TBE info here
And if you havent read this article yet, very good info on the cause, effects and removal of TBE here
Ive used this method on my heli fleet and none exhibit signs of TBE any more

I apologize and say that I would do as requested, BUT I am too afraid to take off the Xtreme swash as I have it flying well now and dont wish to jinx it.
The swash arms are shorter than stock

The Xtreme MSR upgrades are now installed and I have a few flights under my belt.
I managed to rid my MSR of the previous TBE, but replacing the rotor links, new grips (can't wait to test Xtreme ones) and the main shaft. I think the major problem was the main shaft had become worn and had elongated holes where anti rotation collar/head connected. Despite all of this, my heli has tail wag, which it has always had unfortunately and I wouldn't be surprised if it was the gyro causing this. With some tinkering, I now have the heli flying GREAT even with manageable tail wag.
I find the MSR now more responsive and precise with the Xtreme swash and even on the lower swash settings, it still gets up and goes when its told to do so. I have only flown indoors thus far and haven't let it loose yet - waiting for gym time, but I have no doubt the more aggressive swash settings will make this a rocket heli.
I have one flight on the Xtreme 150 Li-Po and it is very comparable in regards to power and flight times of EFlite's 150 Li-Po; mind you I have only one flight thus far and this could change. The benefits of this battery are that it is basically the same length of the EFlite 120 Li-Po, save for the fact that its tighter in the battery tray. Now, this should be a benefit in my opinion because if your like me and go from using EFlite 150 - 120 Li-Po's, you find yourself having to re-adjust trims for the difference in CG. With the Xtreme battery, you shouldn't have to adjust CG.
So far I am very happy with these upgrades, and look forward to testing the other upgrades to come.

Thanks for all the info
So very happy she is flying so wonderfully for you now
Love the new canopy Syma107 or S10?
|Mar 15, 2010, 11:38 PM|
The canopy is a Xtreme fuse for the MCX that I fitted to the MSR a while back. BUT apparently Xtreme is making a fuse specifically for the MSR, so I hope to get one of those to paint
