OK maybe not AAAAALLL you need to know, but with everything I have seen and done with my mSR and problems many folks are having, including the owner of my LHS I feel that the info below is all you need to know to get going. Feel free to add more gotchas or call me out if I am way off. I only have my mSR and what I have seen folks going through online. I also posted this in another thread, but felt it was good enough to starts a new one. Thanks,

Hey guys I didn't have time to sit down and read every single post, but I had some goofy issues with the mSR after I started using it for a while. I have a DX6i, started a new Helicopter model and did the bind process.
First off it looks like this little FP likes to kind of swing back and fourth a little. I think it is a side effect of the stability of the heli. There are really only 3 things you need to be careful of.
1. If you have BNF, make sure you set it up as airplane and you only need to add a little trim with the trim buttons. No sub trim. All other settings are default. Throttle, rudder, everything DEFAULT.
2. Make sure the tail fan is perfectly aligned with the main shaft or it will not hover, it will start wanting to moved in big circles over and over getting worse and worse. It will be a PAIN to fly as well. I have only gotten a very close look at my mSR but the mainshaft on mine is slightly off by a few degrees. I think it did this so the heli does not lean to one side like most small heli's like to do, especially with electric tail fans.
3. Don't over tighten the blades. The heli will wobble terribly and be very hard to control. It also looks/sounds terrible.
Thats it. No tweaking is needed with this guy. It won't fly like your CP heli, but is still a LOT of fun to fly. Some other interesting flight characteristics. It seems to go backwards slowly but is quick to stop if you pull back on your cyclic. You can do a fun "slingshot" if you time it right. The heli likes to sort of swing forward and back a little like a Co-Ax but not as bad if you get the swing right, and have LOTS of room, you can go backward, then catch the swing, it subtle. Then give it full forward cyclic and some throttle to keep it up in the air and ZOOOOOOM off she goes REALLY fast, startlingly fast actually.
The mSR is better at responding to left anf right cyclic. I have no idea why. If you are having a little trouble getting her to go forward or backward, add a little left or right cyclic. Most spectators won't even notice. This is especially helpful in wind and she won't come back to you using forward, and especially backward cyclic. Turn her left or right facing and give strong left or right cyclic so she comes to you.
Another thing I noticed is breaking points. The tiny linkage rods that connect the fly-bar to the blade grips at the very top of the head move up and down through some guides. I took the linkage rods and used some fine sand paper to sanded down the little plastic nubs in the middle were the injection molding is put in. It was actually binding on the guides. This made a huge difference. Finally, the first place mine broke was the blade grips, they are screwed to each other and in a good crash they stripped apart. Some of the plastic around the screws is suuuuper thin and seems to crack easy. Add some plastic lock tight and mayne a tiny tab of rubber cement ware the pieces join under the screws. I ended up using CA, but I know it won't last for ever. I would rather replace the parts but I can't buy anything yet.
I am still a beginner with my TREX, but I think I am between beginner and intermediate with my mSR. Hope this info helps.
Note: I got home from work and realized the information I listed for the linkage arm from the fly-bar to the swash was wrong. It was the fly-bar to the blade grips. But it would not hurt to sand off the nubs in the middle of the linkage arms going from the fly-bar to the swash as well even though they don't need to mover as much. Hope this help and thanks for any feedback.
