I enjoyed the original review of the Sabre by Mr. Heer, by the way. Well done. I do have a few suggestions and comments of my own, if I may be so bold as to post them here...
First off, regarding the (almost perpetual) loss of the tail rotor and gear, I have found that using a longer grommit on the end of the shaft, or even using two grommits at the end, will usually secure the rotor in place through even the roughest "unexpected landings". Alternately, the little rubber slip prevention plugs from the bottom of a small plastic desktop drawer set (available at you favorite neighborhood retail megastore) work equally well, provided they have a hole in the end (you know...those little clear plastic sets of drawers we all use to hold spare parts, screws, glue, etc)
With regard to the cyclic sensitivity of the Sabre, which can be difficult to master in the early stages, I recommend inserting a small soft rubber O-ring on the shaft between the swashplate and the rotor head assembly. This will help to dampen the cyclic response, and make those large stick movements a little easier to recover from. My Brother-In-Law showed me this trick, and it helped me to get a handle on "easing" into cyclic movements, and controlling the heli was much easier. After a short time with the O-ring, I found that I was in a position where I had good control, but now wanted to regain some of that cyclic response to push the heli a bit more. Solution: remove the O-ring. I was quite surprised at how easy it was to maintain control of the heli after a few flights, even without the dampening effect of the O-ring.
Head Stiffener: The head connector supplied with the Sabre is decent for the first few flights, but then it tends to lose it's hold on the rotors. I went through about 6 of these things in a short time, either stripping the screws in an effort to re-tighten the rotors (again), or simply busting them through "unsolicited contact" with objects of various densities and monetary value Having those rotors flapping around all the time can get frustrating. I have switched over to an after-market head stiffener with a carbon-fiber support across the top, secured by screws with top and bottom mounted nuts. The blades can be tightened down quite easily, and they don't loosen up nearly as fast as with the factory head connector.
Sabre Frame: I have found, quite unfortunately, that the stock Sabre frame has a very annoying tendency to snap in half right at the juncture between the body and the tail boom mount (under the left-hand servo mount). I have gone through 2 of these so far, snapping one in the exact same place only hours after replacing it. Maybe I'm too hard on my frames, but I'd suggest switching over to a better frame as soon as possible. I'm using the HeliFever carbon frame right now, and it works pretty well. You just have to make sure you use LockTite on all of the little screws as you put them in, or you will forever be losing them (especially the servo mounting screws..which can have deleterious effects on your flight enjoyment if they happen to come loose mid-flight).
Rotor Head: The Sabre's plastic rotor head is notoriously fragile. My Brother-In_Law and I have gone through about a half dozen or so of these over the past 2 months or so. They have a nasty tendency to break right below the rotor bearings. We have both since switched over to aluminum head connectors, and I have not had to replace one yet. I strongly suggest switching to aluminum as soon as you can. We get our from a gentleman in Canada, who manufactures them. I will post his contact info after I get his permission.
Anyway, I have gotten countless hours of enjoyment out of my stock Sabre, and have continued to make this heli my workhorse even after a few minor modifications. The fixed-pitch rotor design is easy to learn, the heli is easy and economical to repair, but still rugged enough to take much of the punishment a first-time flyer (like myself) can dish out. I highly recommend the Sabre for anyone who wishes to get into the hobby, but doesn't have the immediate capital resources to go with the larger collective-pitch helis.
That's it. I think I've said enough for one day.

Gee I have one of those
My sabre is RTF or is that BCF (buy, charge, fly)
I had to have one of those air hogs (big mistake) they don't last long enuf.
So I did some research (thank god) and decided on the EF SABRE.
I still can't fly it but I had quite a bit of fun trying.
I tried chasing a cat and busted the rotorhead. And i got tired of waiting for the battery to charge so bought an extra. I've worn out the orange pingpong balls (starter kit) trying to get the hang of it but my reaction time is too slow.
They do get erratic outside in the breeze so I bet the security people at Target get lots of laffs on their underground parking cameras, probably thought it was some weird rc car till I went airborne with it.
I haven't found a LARGE enough indoor spot to practice in ( I need lots of room) so I fight the wind, trees, buildings, ground, etc.
This sabre is NOT really a beginners in a true sense of the word. It is truly a REAL RC helicopter and as I age I am getting slower and find flying (learning) harder. But alas The EF Sabre is forgiving and probably the cheapest to repair.
Gotta go, here comes that cat!
